Amazon.S3.Model

Container for the parameters to the AbortMultipartUpload operation. This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty.

For information about permissions required to use the multipart upload, see Multipart Upload and Permissions.

The following operations are related to AbortMultipartUpload:

• CreateMultipartUpload

• UploadPart

• CompleteMultipartUpload

• ListParts

• ListMultipartUploads

Returns information about the AbortMultipartUpload response metadata. The AbortMultipartUpload operation has a void result type.

Bucket accelerate configuration.

A container for information about access control for replicas.

Class for AnalyticsAndOperator

A conjunction (logical AND) of predicates, which is used in evaluating a metrics filter. The operator must have at least two predicates, and an object must match all of the predicates in order for the filter to apply.

Class for AnalyticsConfiguration

Class for AnalyticsExportDestination

Filter class for Metrics.

Filter Predicate abstract class for specific filter types to be derived from.

Abstract class that can be used over logical filter predicates,i.e. AND/OR.

Class for AnalyticsPrefixPredicate

The prefix used when evaluating a metrics filter.

Class for AnalyticsS3BucketDestination

Class for MetricsTagPredicate

The tag used when evaluating a metrics filter.

The requested bucket name is not available. The bucket namespace is shared by all users of the system. Select a different name and try again.

The bucket you tried to create already exists, and you own it. Amazon S3 returns this error in all Amazon Web Services Regions except in the North Virginia Region. For legacy compatibility, if you re-create an existing bucket that you already own in the North Virginia Region, Amazon S3 returns 200 OK and resets the bucket access control lists (ACLs).

Contains information about the Bucket

This class represents the byte range for a range GET from S3.

Contains all the possible checksum or digest values for an object.

Container for the parameters to the CompleteMultipartUpload operation. Completes a multipart upload by assembling previously uploaded parts.

You first initiate the multipart upload and then upload all parts using the UploadPart operation or the UploadPartCopy operation. After successfully uploading all relevant parts of an upload, you call this CompleteMultipartUpload operation to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the CompleteMultipartUpload request, you must provide the parts list and ensure that the parts list is complete. The CompleteMultipartUpload API operation concatenates the parts that you provide in the list. For each part in the list, you must provide the PartNumber value and the ETag value that are returned after that part was uploaded.

The processing of a CompleteMultipartUpload request could take several minutes to finalize. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. A request could fail after the initial 200 OK response has been sent. This means that a 200 OK response can contain either a success or an error. The error response might be embedded in the 200 OK response. If you call this API operation directly, make sure to design your application to parse the contents of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throw an exception (or, for the SDKs that don't use exceptions, they return an error).

Note that if CompleteMultipartUpload fails, applications should be prepared to retry any failed requests (including 500 error responses). For more information, see Amazon S3 Error Best Practices.

For more information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Special errors

• Error Code: EntityTooSmall

  • Description: Your proposed upload is smaller than the minimum allowed object size. Each part must be at least 5 MB in size, except the last part.

  • HTTP Status Code: 400 Bad Request

• Error Code: InvalidPart

  • Description: One or more of the specified parts could not be found. The part might not have been uploaded, or the specified ETag might not have matched the uploaded part's ETag.

  • HTTP Status Code: 400 Bad Request

• Error Code: InvalidPartOrder

  • Description: The list of parts was not in ascending order. The parts list must be specified in order by part number.

  • HTTP Status Code: 400 Bad Request

• Error Code: NoSuchUpload

  • Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.

  • HTTP Status Code: 404 Not Found

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

The following operations are related to CompleteMultipartUpload:

• CreateMultipartUpload

• UploadPart

• AbortMultipartUpload

• ListParts

• ListMultipartUploads

Returns information about the CompleteMultipartUpload response and response metadata.

The Continuation Event.

Container for the parameters to the CopyObject operation. Creates a copy of an object that is already stored in Amazon S3.

You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API.

You can copy individual objects between general purpose buckets, between directory buckets, and between general purpose buckets and directory buckets.

Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.

Authentication and authorization

All CopyObject requests must be authenticated and signed by using IAM credentials (access key ID and secret access key for the IAM identities). All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. For more information, see REST Authentication.

Directory buckets - You must use the IAM credentials to authenticate and authorize your access to the CopyObject API operation, instead of using the temporary security credentials through the CreateSession API operation.

Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.

Permissions

You must have read access to the source object and write access to the destination bucket.

• General purpose bucket permissions - You must have permissions in an IAM policy based on the source and destination bucket types in a CopyObject operation.

  • If the source object is in a general purpose bucket, you must have s3:GetObject permission to read the source object that is being copied.

  • If the destination bucket is a general purpose bucket, you must have s3:PutObject permission to write the object copy to the destination bucket.

• Directory bucket permissions - You must have permissions in a bucket policy or an IAM identity-based policy based on the source and destination bucket types in a CopyObject operation.

  • If the source object that you want to copy is in a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to read the object. By default, the session is in the ReadWrite mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode condition key to ReadOnly on the copy source bucket.

  • If the copy destination is a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to write the object to the destination. The s3express:SessionMode condition key can't be set to ReadOnly on the copy destination bucket.

  For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.

Response and special errors

When the request is an HTTP 1.1 request, the response is chunk encoded. When the request is not an HTTP 1.1 request, the response would not contain the Content-Length. You always need to read the entire response body to check if the copy succeeds. to keep the connection alive while we copy the data.

• If the copy is successful, you receive a response with information about the copied object.

• A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. A 200 OK response can contain either a success or an error.

  • If the error occurs before the copy action starts, you receive a standard Amazon S3 error.

  • If the error occurs during the copy operation, the error response is embedded in the 200 OK response. For example, in a cross-region copy, you may encounter throttling and receive a 200 OK response. For more information, see Resolve the Error 200 response when copying objects to Amazon S3. The 200 OK status code means the copy was accepted, but it doesn't mean the copy is complete. Another example is when you disconnect from Amazon S3 before the copy is complete, Amazon S3 might cancel the copy and you may receive a 200 OK response. You must stay connected to Amazon S3 until the entire response is successfully received and processed.

    If you call this API operation directly, make sure to design your application to parse the content of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throw an exception (or, for the SDKs that don't use exceptions, they return an error).

Charge

The copy request charge is based on the storage class and Region that you specify for the destination object. The request can also result in a data retrieval charge for the source if the source storage class bills for data retrieval. If the copy source is in a different region, the data transfer is billed to the copy source account. For pricing information, see Amazon S3 pricing.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

The following operations are related to CopyObject:

• PutObject

• GetObject

Returns information about the CopyObject response and response metadata.

Container for the parameters to the CopyPart operation. Uploads a part by copying data from an existing object as data source. To specify the data source, you add the request header x-amz-copy-source in your request. To specify a byte range, you add the request header x-amz-copy-source-range in your request.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide.

You must initiate a multipart upload before you can upload any part. In response to your initiate request, Amazon S3 returns the upload ID, a unique identifier that you must include in your upload part request.

For conceptual information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide. For information about copying objects using a single atomic action vs. a multipart upload, see Operations on Objects in the Amazon S3 User Guide.

Authentication and authorization

All UploadPartCopy requests must be authenticated and signed by using IAM credentials (access key ID and secret access key for the IAM identities). All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. For more information, see REST Authentication.

Directory buckets - You must use IAM credentials to authenticate and authorize your access to the UploadPartCopy API operation, instead of using the temporary security credentials through the CreateSession API operation.

Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.

Permissions

You must have READ access to the source object and WRITE access to the destination bucket.

• General purpose bucket permissions - You must have the permissions in a policy based on the bucket types of your source bucket and destination bucket in an UploadPartCopy operation.

  • If the source object is in a general purpose bucket, you must have the s3:GetObject permission to read the source object that is being copied.

  • If the destination bucket is a general purpose bucket, you must have the s3:PutObject permission to write the object copy to the destination bucket.

  For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.

• Directory bucket permissions - You must have permissions in a bucket policy or an IAM identity-based policy based on the source and destination bucket types in an UploadPartCopy operation.

  • If the source object that you want to copy is in a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to read the object . By default, the session is in the ReadWrite mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode condition key to ReadOnly on the copy source bucket.

  • If the copy destination is a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to write the object to the destination. The s3express:SessionMode condition key cannot be set to ReadOnly on the copy destination.

  For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.

Encryption

• General purpose buckets - For information about using server-side encryption with customer-provided encryption keys with the UploadPartCopy operation, see CopyObject and UploadPart.

• Directory buckets - For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

Special errors

Container for the parameters to the DeleteBucketIntelligentTieringConfiguration operation. Deletes the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the DeleteBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

To ensure that bucket owners don't inadvertently lock themselves out of their own buckets, the root principal in a bucket owner's Amazon Web Services account can perform the GetBucketPolicy, PutBucketPolicy, and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal's access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

• General purpose bucket permissions - The s3:DeleteBucketPolicy permission is required in a policy. For more information about general purpose buckets bucket policies, see Using Bucket Policies and User Policies in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation, you must have the s3express:DeleteBucketPolicy permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

Container for the parameters to the DeleteBucketReplication operation. Deletes the replication configuration from the bucket.

To use this operation, you must have permissions to perform the s3:PutReplicationConfiguration action. The bucket owner has these permissions by default and can grant it to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

For information about replication configuration, see Replication in the Amazon S3 User Guide.

The following operations are related to DeleteBucketReplication:

• PutBucketReplication

• GetBucketReplication

Returns information about the DeleteBucketReplication response metadata. The DeleteBucketReplication operation has a void result type.

Container for the parameters to the DeleteBucket operation. Deletes the S3 bucket. All objects (including all object versions and delete markers) in the bucket must be deleted before the bucket itself can be deleted.

• Directory buckets - If multipart uploads in a directory bucket are in progress, you can't delete the bucket until all the in-progress multipart uploads are aborted or completed.

• Directory buckets - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format https://s3express-control.region_code.amazonaws.com/bucket-name. Virtual-hosted-style requests aren't supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - You must have the s3:DeleteBucket permission on the specified bucket in a policy.

• Directory bucket permissions - You must have the s3express:DeleteBucket permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is s3express-control.region.amazonaws.com.

The following operations are related to DeleteBucket:

• CreateBucket

• DeleteObject

Returns information about the DeleteBucket response metadata. The DeleteBucket operation has a void result type.

The parameters to request deletion of a tag set from a bucket.

Returns information about the DeleteBucketTagging response metadata. The DeleteBucketTagging operation has a void result type.

Container for the parameters to the DeleteLifecycleConfiguration operation.

This operation is not supported by directory buckets.

Deletes the lifecycle configuration from the specified bucket. Amazon S3 removes all the lifecycle configuration rules in the lifecycle subresource associated with the bucket. Your objects never expire, and Amazon S3 no longer automatically deletes any objects on the basis of rules contained in the deleted lifecycle configuration.

To use this operation, you must have permission to perform the s3:PutLifecycleConfiguration action. By default, the bucket owner has this permission and the bucket owner can grant this permission to others.

There is usually some time lag before lifecycle configuration deletion is fully propagated to all the Amazon S3 systems.

For more information about the object expiration, see Elements to Describe Lifecycle Actions.

Related actions include:

• PutBucketLifecycleConfiguration

• GetBucketLifecycleConfiguration

Returns information about the DeleteLifecycleConfiguration response metadata. The DeleteLifecycleConfiguration operation has a void result type.

Specifies whether Amazon S3 replicates delete markers. If you specify a Filter in your replication configuration, you must also include a DeleteMarkerReplication element. If your Filter includes a Tag element, the DeleteMarkerReplicationStatus must be set to Disabled, because Amazon S3 does not support replicating delete markers for tag-based rules. For an example configuration, see Basic Rule Configuration.

For more information about delete marker replication, see Basic Rule Configuration.

Container for the parameters to the DeleteObject operation. Removes an object from a bucket. The behavior depends on the bucket's versioning state:

• If bucket versioning is not enabled, the operation permanently deletes the object.

• If bucket versioning is enabled, the operation inserts a delete marker, which becomes the current version of the object. To permanently delete an object in a versioned bucket, you must include the object’s versionId in the request. For more information about versioning-enabled buckets, see Deleting object versions from a versioning-enabled bucket.

• If bucket versioning is suspended, the operation removes the object that has a null versionId, if there is one, and inserts a delete marker that becomes the current version of the object. If there isn't an object with a null versionId, and all versions of the object have a versionId, Amazon S3 does not remove the object and only inserts a delete marker. To permanently delete an object that has a versionId, you must include the object’s versionId in the request. For more information about versioning-suspended buckets, see Deleting objects from versioning-suspended buckets.

To remove a specific version, you must use the versionId query parameter. Using this query parameter permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header x-amz-delete-marker to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS. For more information about MFA Delete, see Using MFA Delete in the Amazon S3 User Guide. To see sample requests that use versioning, see Sample Request.

You can delete objects by explicitly calling DELETE Object or calling (PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions.

Permissions

• General purpose bucket permissions - The following permissions are required in your policies when your DeleteObjects request includes specific headers.

  • s3:DeleteObject - To delete an object from a bucket, you must always have the s3:DeleteObject permission.

  • s3:DeleteObjectVersion - To delete a specific version of an object from a versioning-enabled bucket, you must have the s3:DeleteObjectVersion permission.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

The following action is related to DeleteObject:

• PutObject

Returns information about the DeleteObject response and response metadata.

Container for the parameters to the DeleteObjects operation. This operation enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this operation provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request can contain a list of up to 1,000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete operation and returns the result of that delete, success or failure, in the response. If the object specified in the request isn't found, Amazon S3 confirms the deletion by returning the result as deleted.

The operation supports two modes for the response: verbose and quiet. By default, the operation uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete operation encountered an error. For a successful deletion in a quiet mode, the operation does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - The following permissions are required in your policies when your DeleteObjects request includes specific headers.

  • s3:DeleteObject - To delete an object from a bucket, you must always specify the s3:DeleteObject permission.

  • s3:DeleteObjectVersion - To delete a specific version of an object from a versiong-enabled bucket, you must specify the s3:DeleteObjectVersion permission.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Content-MD5 request header

• General purpose bucket - The Content-MD5 request header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

• Directory bucket - The Content-MD5 request header or a additional checksum request header (including x-amz-checksum-crc32, x-amz-checksum-crc32c, x-amz-checksum-sha1, or x-amz-checksum-sha256) is required for all Multi-Object Delete requests.

• GetBucketPolicyStatus

This is the response object from the DeletePublicAccessBlock operation.

Specifies encryption-related information for an Amazon S3 bucket that is a destination for replicated objects.

Encryption type mismatch exception.

The End Event.

If the CreateBucketMetadataTableConfiguration request succeeds, but S3 Metadata was unable to create the table, this structure contains the error code and error message.

A container for specifying the configuration for Amazon EventBridge.

Optional configuration to replicate existing source bucket objects.

Defines the expiration policy for a given object.

Bucket Represents a set of filter criteria that limits the objects that can trigger event notifications

Specifies the Amazon S3 object key name to filter on. An object key name is the name assigned to an object in your Amazon S3 bucket. You specify whether to filter on the suffix or prefix of the object key name. A prefix is a specific string of characters at the beginning of an object key name, which you can use to organize objects. For example, you can start the key names of related objects with a prefix, such as 2023- or engineering/. Then, you can use FilterRule to find objects in a bucket with key names that have the same prefix. A suffix is similar to a prefix, but it is at the end of the object key name instead of at the beginning.

Container for the parameters to the GetACL operation.

This operation is not supported by directory buckets.

This implementation of the GET action uses the acl subresource to return the access control list (ACL) of a bucket. To use GET to return the ACL of the bucket, you must have the READ_ACP access to the bucket. If READ_ACP permission is granted to the anonymous user, you can return the ACL of the bucket without using an authorization header.

When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.

When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes.

The following operations are related to GetBucketAcl:

This operation is not supported by directory buckets.

Gets the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have GetBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

To ensure that bucket owners don't inadvertently lock themselves out of their own buckets, the root principal in a bucket owner's Amazon Web Services account can perform the GetBucketPolicy, PutBucketPolicy, and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal's access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

• General purpose bucket permissions - The s3:GetBucketPolicy permission is required in a policy. For more information about general purpose buckets bucket policies, see Using Bucket Policies and User Policies in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation, you must have the s3express:GetBucketPolicy permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

GetObjectAttributes combines the functionality of HeadObject and ListParts. All of the data returned with each of those individual calls can be returned with a single call to GetObjectAttributes.

Permissions

• General purpose bucket permissions - To use GetObjectAttributes, you must have READ access to the object. The permissions that you need to use this operation with depend on whether the bucket is versioned. If the bucket is versioned, you need both the s3:GetObjectVersion and s3:GetObjectVersionAttributes permissions for this operation. If the bucket is not versioned, you need the s3:GetObject and s3:GetObjectAttributes permissions. For more information, see Specifying Permissions in a Policy in the Amazon S3 User Guide. If the object that you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found ("no such key") error.

  • If you don't have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Forbidden ("access denied") error.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Encryption

Encryption request headers, like x-amz-server-side-encryption, should not be sent for HEAD requests if your object uses server-side encryption with Key Management Service (KMS) keys (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or server-side encryption with Amazon S3 managed encryption keys (SSE-S3). The x-amz-server-side-encryption header is used when you PUT an object to S3 and want to specify the encryption method. If you include this header in a GET request for an object that uses these types of keys, you’ll get an HTTP 400 Bad Request error. It's because the encryption method can't be changed when you retrieve the object.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers to provide the encryption key for the server to be able to retrieve the object's metadata. The headers are:

• x-amz-server-side-encryption-customer-algorithm

• x-amz-server-side-encryption-customer-key

• x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.

Directory bucket permissions - For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

Versioning

Directory buckets - S3 Versioning isn't enabled and supported for directory buckets. For this API operation, only the null value of the version ID is supported by directory buckets. You can only specify null to the versionId query parameter in the request.

Conditional request headers

Consider the following when using request headers:

• If both of the If-Match and If-Unmodified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 200 OK and the data requested:

  • If-Match condition evaluates to true.

  • If-Unmodified-Since condition evaluates to false.

  For more information about conditional requests, see RFC 7232.

• If both of the If-None-Match and If-Modified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 304 Not Modified:

  • If-None-Match condition evaluates to false.

  • If-Modified-Since condition evaluates to true.

  For more information about conditional requests, see RFC 7232.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

The following actions are related to GetObjectAttributes:

• GetObject

• GetObjectAcl

• GetObjectLegalHold

• GetObjectLockConfiguration

• GetObjectRetention

• GetObjectTagging

• HeadObject

• ListParts

This is the response object from the GetObjectAttributes operation.

Container for the parameters to the GetObjectLegalHold operation.

This operation is not supported by directory buckets.

Gets an object's current legal hold status. For more information, see Locking Objects.

This functionality is not supported for Amazon S3 on Outposts.

The following action is related to GetObjectLegalHold:

• GetObjectAttributes

This is the response object from the GetObjectLegalHold operation.

Container for the parameters to the GetObjectLockConfiguration operation.

This operation is not supported by directory buckets.

Gets the Object Lock configuration for a bucket. The rule specified in the Object Lock configuration will be applied by default to every new object placed in the specified bucket. For more information, see Locking Objects.

The following action is related to GetObjectLockConfiguration:

• GetObjectAttributes

This is the response object from the GetObjectLockConfiguration operation.

Container for the parameters to the GetObjectMetadata operation. The HEAD operation retrieves metadata from an object without returning the object itself. This operation is useful if you're interested only in an object's metadata.

A HEAD request has the same options as a GET operation on an object. The response is identical to the GET response except that there is no response body. Because of this, if the HEAD request generates an error, it returns a generic code, such as 400 Bad Request, 403 Forbidden, 404 Not Found, 405 Method Not Allowed, 412 Precondition Failed, or 304 Not Modified. It's not possible to retrieve the exact exception of these error codes.

Request headers are limited to 8 KB in size. For more information, see Common Request Headers.

Permissions

• General purpose bucket permissions - To use HEAD, you must have the s3:GetObject permission. You need the relevant read object (or version) permission for this operation. For more information, see Actions, resources, and condition keys for Amazon S3 in the Amazon S3 User Guide. For more information about the permissions to S3 API operations by S3 resource types, see Required permissions for Amazon S3 API operations in the Amazon S3 User Guide.

  If the object you request doesn't exist, the error that Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found error.

  • If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Forbidden error.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Encryption

Encryption request headers, like x-amz-server-side-encryption, should not be sent for HEAD requests if your object uses server-side encryption with Key Management Service (KMS) keys (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or server-side encryption with Amazon S3 managed encryption keys (SSE-S3). The x-amz-server-side-encryption header is used when you PUT an object to S3 and want to specify the encryption method. If you include this header in a HEAD request for an object that uses these types of keys, you’ll get an HTTP 400 Bad Request error. It's because the encryption method can't be changed when you retrieve the object.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers to provide the encryption key for the server to be able to retrieve the object's metadata. The headers are:

• x-amz-server-side-encryption-customer-algorithm

• x-amz-server-side-encryption-customer-key

• x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.

Directory bucket permissions - For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

Versioning

• If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.

• If the specified version is a delete marker, the response returns a 405 Method Not Allowed error and the Last-Modified: timestamp response header.

• Directory buckets - Delete marker is not supported by directory buckets.

• Directory buckets - S3 Versioning isn't enabled and supported for directory buckets. For this API operation, only the null value of the version ID is supported by directory buckets. You can only specify null to the versionId query parameter in the request.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

The following actions are related to HeadObject:

• GetObject

• GetObjectAttributes

Returns information about the HeadObject response and response metadata.

Container for the parameters to the GetObject operation. Retrieves an object from Amazon S3.

In the GetObject request, specify the full key name for the object.

General purpose buckets - Both the virtual-hosted-style requests and the path-style requests are supported. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the object key name as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named amzn-s3-demo-bucket, specify the object key name as /amzn-s3-demo-bucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification in the Amazon S3 User Guide.

Directory buckets - Only virtual-hosted-style requests are supported. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named amzn-s3-demo-bucket--use1-az5--x-s3, specify the object key name as /photos/2006/February/sample.jpg. Also, when you make requests to this API operation, your requests are sent to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - You must have the required permissions in a policy. To use GetObject, you must have the READ access to the object (or version). If you grant READ access to the anonymous user, the GetObject operation returns the object without using an authorization header. For more information, see Specifying permissions in a policy in the Amazon S3 User Guide.

  If you include a versionId in your request header, you must have the s3:GetObjectVersion permission to access a specific version of an object. The s3:GetObject permission is not required in this scenario.

  If you request the current version of an object without a specific versionId in the request header, only the s3:GetObject permission is required. The s3:GetObjectVersion permission is not required in this scenario.

  If the object that you request doesn’t exist, the error that Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found error.

  • If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Access Denied error.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Storage classes

If the object you are retrieving is stored in the S3 Glacier Flexible Retrieval storage class, the S3 Glacier Deep Archive storage class, the S3 Intelligent-Tiering Archive Access tier, or the S3 Intelligent-Tiering Deep Archive Access tier, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this operation returns an InvalidObjectState error. For information about restoring archived objects, see Restoring Archived Objects in the Amazon S3 User Guide.

Directory buckets - For directory buckets, only the S3 Express One Zone storage class is supported to store newly created objects. Unsupported storage class values won't write a destination object and will respond with the HTTP status code 400 Bad Request.

Encryption

Encryption request headers, like x-amz-server-side-encryption, should not be sent for the GetObject requests, if your object uses server-side encryption with Amazon S3 managed encryption keys (SSE-S3), server-side encryption with Key Management Service (KMS) keys (SSE-KMS), or dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS). If you include the header in your GetObject requests for the object that uses these types of keys, you’ll get an HTTP 400 Bad Request error.

Overriding response header values through the request

There are times when you want to override certain response header values of a GetObject response. For example, you might override the Content-Disposition response header value through your GetObject request.

You can override values for a set of response headers. These modified response header values are included only in a successful response, that is, when the HTTP status code 200 OK is returned. The headers you can override using the following query parameters in the request are a subset of the headers that Amazon S3 accepts when you create an object.

The response headers that you can override for the GetObject response are Cache-Control, Content-Disposition, Content-Encoding, Content-Language, Content-Type, and Expires.

To override values for a set of response headers in the GetObject response, you can use the following query parameters in the request.

• response-cache-control

• response-content-disposition

• response-content-encoding

• response-content-language

• response-content-type

• response-expires

When you use these parameters, you must sign the request by using either an Authorization header or a presigned URL. These parameters cannot be used with an unsigned (anonymous) request.

HTTP Host header syntax

Container for the parameters to the GetObjectTagging operation.

This operation is not supported by directory buckets.

Returns the tag-set of an object. You send the GET request against the tagging subresource associated with the object.

To use this operation, you must have permission to perform the s3:GetObjectTagging action. By default, the GET action returns information about current version of an object. For a versioned bucket, you can have multiple versions of an object in your bucket. To retrieve tags of any other version, use the versionId query parameter. You also need permission for the s3:GetObjectVersionTagging action.

By default, the bucket owner has this permission and can grant this permission to others.

For information about the Amazon S3 object tagging feature, see Object Tagging.

The following actions are related to GetObjectTagging:

• DeleteObjectTagging

• GetObjectAttributes

• PutObjectTagging

Returns information about the GetObjectTagging response and response metadata.

Container for the parameters to the GetObjectTorrent operation.

This operation is not supported by directory buckets.

Returns torrent files from a bucket. BitTorrent can save you bandwidth when you're distributing large files.

To use GET, you must have READ access to the object.

This functionality is not supported for Amazon S3 on Outposts.

The following action is related to GetObjectTorrent:

• GetObject

Returns information about the GetObjectTorrent response and response metadata.

The parameters to create a pre-signed URL to a bucket or object.

The parameters for a pre-signed URL to a bucket or object as a string.

Container for the parameters to the GetPublicAccessBlock operation.

This operation is not supported by directory buckets.

Retrieves the PublicAccessBlock configuration for an Amazon S3 bucket. To use this operation, you must have the s3:GetBucketPublicAccessBlock permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy.

For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public".

The following operations are related to GetPublicAccessBlock:

• Using Amazon S3 Block Public Access

• PutPublicAccessBlock

• GetPublicAccessBlock

• DeletePublicAccessBlock

This is the response object from the GetPublicAccessBlock operation.

Container for the parameters to the HeadBucket operation. You can use this operation to determine if a bucket exists and if you have permission to access it. The action returns a 200 OK if the bucket exists and you have permission to access it.

If the bucket does not exist or you do not have permission to access it, the HEAD request returns a generic 400 Bad Request, 403 Forbidden or 404 Not Found code. A message body is not included, so you cannot determine the exception beyond these HTTP response codes.

Authentication and authorization

All HeadBucket requests must be authenticated and signed by using IAM credentials (access key ID and secret access key for the IAM identities). All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. For more information, see REST Authentication.

Directory bucket - You must use IAM credentials to authenticate and authorize your access to the HeadBucket API operation, instead of using the temporary security credentials through the CreateSession API operation.

Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.

Permissions

• General purpose bucket permissions - To use this operation, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Managing access permissions to your Amazon S3 resources in the Amazon S3 User Guide.

• Directory bucket permissions - You must have the s3express:CreateSession permission in the Action element of a policy. By default, the session is in the ReadWrite mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode condition key to ReadOnly on the bucket.

  For more information about example bucket policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

Returns information about the HeadBucket response metadata. The HeadBucket operation has a void result type.

This class contains the headers for an S3 object.

Container for the parameters to the InitiateMultipartUpload operation. This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart). You also include this upload ID in the final request to either complete or abort the multipart upload request. For more information about multipart uploads, see Multipart Upload Overview in the Amazon S3 User Guide.

After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stops charging you for storing them only after you either complete or abort a multipart upload.

If you have configured a lifecycle rule to abort incomplete multipart uploads, the created multipart upload must be completed within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Configuration.

Request signing

For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - For information about the permissions required to use the multipart upload API, see Multipart upload and permissions in the Amazon S3 User Guide.

  To perform a multipart upload with encryption by using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions and Protecting data using server-side encryption with Amazon Web Services KMS in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Encryption

• General purpose buckets - Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. Amazon S3 automatically encrypts all new objects that are uploaded to an S3 bucket. When doing a multipart upload, if you don't specify encryption information in your request, the encryption setting of the uploaded parts is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the uploaded parts. When you perform a CreateMultipartUpload operation, if you want to use a different type of encryption setting for the uploaded parts, you can request that Amazon S3 encrypts the object with a different encryption key (such as an Amazon S3 managed key, a KMS key, or a customer-provided key). When the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the CreateMultipartUpload request.

  • Use KMS keys (SSE-KMS) that include the Amazon Web Services managed key (aws/s3) and KMS customer managed keys stored in Key Management Service (KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.

    • x-amz-server-side-encryption

    • x-amz-server-side-encryption-aws-kms-key-id

    • x-amz-server-side-encryption-context

    • If you specify x-amz-server-side-encryption:aws:kms, but don't provide x-amz-server-side-encryption-aws-kms-key-id, Amazon S3 uses the Amazon Web Services managed key (aws/s3 key) in KMS to protect the data.

    • To perform a multipart upload with encryption by using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions and Protecting data using server-side encryption with Amazon Web Services KMS in the Amazon S3 User Guide.

    • If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role is in a different account from the key, then you must have the permissions on both the key policy and your IAM user or role.

    • All GET and PUT requests for an object protected by KMS fail if you don't make them by using Secure Sockets Layer (SSL), Transport Layer Security (TLS), or Signature Version 4. For information about configuring any of the officially supported Amazon Web Services SDKs and Amazon Web Services CLI, see Specifying the Signature Version in Request Authentication in the Amazon S3 User Guide.

    For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys in the Amazon S3 User Guide.

  • Use customer-provided encryption keys (SSE-C) – If you want to manage your own encryption keys, provide all the following headers in the request.

    • x-amz-server-side-encryption-customer-algorithm

    • x-amz-server-side-encryption-customer-key

    • x-amz-server-side-encryption-customer-key-MD5

    For more information about server-side encryption with customer-provided encryption keys (SSE-C), see Protecting data using server-side encryption with customer-provided encryption keys (SSE-C) in the Amazon S3 User Guide.

• Directory buckets -For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

This is the response object from the ListDirectoryBuckets operation.

Container for the parameters to the ListMultipartUploads operation. This operation lists in-progress multipart uploads in a bucket. An in-progress multipart upload is a multipart upload that has been initiated by the CreateMultipartUpload request, but has not yet been completed or aborted.

Directory buckets - If multipart uploads in a directory bucket are in progress, you can't delete the bucket until all the in-progress multipart uploads are aborted or completed.

The ListMultipartUploads operation returns a maximum of 1,000 multipart uploads in the response. The limit of 1,000 multipart uploads is also the default value. You can further limit the number of uploads in a response by specifying the max-uploads request parameter. If there are more than 1,000 multipart uploads that satisfy your ListMultipartUploads request, the response returns an IsTruncated element with the value of true, a NextKeyMarker element, and a NextUploadIdMarker element. To list the remaining multipart uploads, you need to make subsequent ListMultipartUploads requests. In these requests, include two query parameters: key-marker and upload-id-marker. Set the value of key-marker to the NextKeyMarker value from the previous response. Similarly, set the value of upload-id-marker to the NextUploadIdMarker value from the previous response.

For more information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Sorting of multipart uploads in response

• General purpose bucket - In the ListMultipartUploads response, the multipart uploads are sorted based on two criteria:

  • Key-based sorting - Multipart uploads are initially sorted in ascending order based on their object keys.

  • Time-based sorting - For uploads that share the same object key, they are further sorted in ascending order based on the upload initiation time. Among uploads with the same key, the one that was initiated first will appear before the ones that were initiated later.

• Directory bucket - In the ListMultipartUploads response, the multipart uploads aren't sorted lexicographically based on the object keys.

Amazon S3 keys for log objects are partitioned in the following format:

[DestinationPrefix][SourceAccountId]/[SourceRegion]/[SourceBucket]/[YYYY]/[MM]/[DD]/[YYYY]-[MM]-[DD]-[hh]-[mm]-[ss]-[UniqueString]

PartitionedPrefix defaults to EventTime delivery when server access logs are delivered.

The container element for this bucket's public-policy status.

The Progress event details.

The Progress Event.

The container element for all Public Access Block configuration options. You can enable the configuration options in any combination.

Amazon S3 considers a bucket policy public unless at least one of the following conditions is true:

1. The policy limits access to a set of CIDRs using aws:SourceIp. For more information on CIDR, see http://www.rfc-editor.org/rfc/rfc4632.txt

2. The policy grants permissions, not including any "bad actions," to one of the following:

   • A fixed AWS principal, user, role, or service principal

   • A fixed aws:SourceArn

   • A fixed aws:SourceVpc

   • A fixed aws:SourceVpce

   • A fixed aws:SourceOwner

   • A fixed aws:SourceAccount

   • A fixed value of s3:x-amz-server-side-encryption-aws-kms-key-id

   • A fixed value of aws:userid outside the pattern "AROLEID:*"

"Bad actions" are those that could expose the data inside a bucket to reads or writes by the public. These actions are s3:Get*, s3:List*, s3:AbortMultipartUpload, s3:Delete*, s3:Put*, and s3:RestoreObject.

The star notation for bad actions indicates that all matching operations are considered bad actions. For example, because s3:Get* is a bad action, s3:GetObject, s3:GetObjectVersion, and s3:GetObjectAcl are all bad actions.

Container for the parameters to the PutACL operation.

This operation is not supported by directory buckets.

Sets the permissions on an existing bucket using access control lists (ACL). For more information, see Using ACLs. To set the ACL of a bucket, you must have the WRITE_ACP permission.

You can use one of the following two ways to set a bucket's permissions:

• Specify the ACL in the request body

• Specify permissions using request headers

Depending on your application needs, you may choose to set the ACL on a bucket using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, then you can continue to use that approach.

Permissions

You can set access permissions by using one of the following methods:

• Specify a canned ACL with the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-acl. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL.

• Specify access permissions explicitly with the x-amz-grant-read, x-amz-grant-read-acp, x-amz-grant-write-acp, and x-amz-grant-full-control headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use the x-amz-acl header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.

  You specify each grantee as a type=value pair, where the type is one of the following:

  • id – if the value specified is the canonical user ID of an Amazon Web Services account

  • uri – if you are granting permissions to a predefined group

  • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)

    • US West (N. California)

    • US West (Oregon)

    • Asia Pacific (Singapore)

    • Asia Pacific (Sydney)

    • Asia Pacific (Tokyo)

    • Europe (Ireland)

    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

  For example, the following x-amz-grant-write header grants create, overwrite, and delete objects permission to LogDelivery group predefined by Amazon S3 and two Amazon Web Services accounts identified by their email addresses.

  x-amz-grant-write: uri="http://acs.amazonaws.com/groups/s3/LogDelivery", id="111122223333",
              id="555566667777" 
  

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

• By the person's ID:

  <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName>
              </Grantee>
  

  DisplayName is optional and ignored in the request

• By URI:

  <>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<>

• By Email address:

  <>Grantees@email.com<>&

  The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

  Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)

  • US West (N. California)

  • US West (Oregon)

  • Asia Pacific (Singapore)

  • Asia Pacific (Sydney)

  • Asia Pacific (Tokyo)

  • Europe (Ireland)

  • South America (São Paulo)

  For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

The following operations are related to PutBucketAcl:

• CreateBucket

• DeleteBucket

• GetObjectAcl

Returns information about the PutObjectAcl response metadata. The PutAcl operation has a void result type.

Container for the parameters to the PutBucketAccelerateConfiguration operation.

This operation is not supported by directory buckets.

Sets the accelerate configuration of an existing bucket. Amazon S3 Transfer Acceleration is a bucket-level feature that enables you to perform faster data transfers to Amazon S3.

To use this operation, you must have permission to perform the s3:PutAccelerateConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

The Transfer Acceleration state of a bucket can be set to one of the following two values:

• Enabled � Enables accelerated data transfers to the bucket.

• Suspended � Disables accelerated data transfers to the bucket.

The GetBucketAccelerateConfiguration action returns the transfer acceleration state of a bucket.

After setting the Transfer Acceleration state of a bucket to Enabled, it might take up to thirty minutes before the data transfer rates to the bucket increase.

The name of the bucket used for Transfer Acceleration must be DNS-compliant and must not contain periods (".").

For more information about transfer acceleration, see Transfer Acceleration.

The following operations are related to PutBucketAccelerateConfiguration:

• GetBucketAccelerateConfiguration

• CreateBucket

The response for the PutBucketAccelerateConfiguration operation.

Adds an object to a bucket.

Container for the parameters to the PutBucketAnalyticsConfiguration operation.

This operation is not supported by directory buckets.

Sets an analytics configuration for the bucket (specified by the analytics configuration ID). You can have up to 1,000 analytics configurations per bucket.

You can choose to have storage class analysis export analysis reports sent to a comma-separated values (CSV) flat file. See the DataExport request element. Reports are updated daily and are based on the object filters that you configure. When selecting data export, you specify a destination bucket and an optional destination prefix where the file is written. You can export the data to a destination bucket in a different account. However, the destination bucket must be in the same Region as the bucket that you are making the PUT analytics configuration to. For more information, see Amazon S3 Analytics – Storage Class Analysis.

To use this operation, you must have permissions to perform the s3:PutAnalyticsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

Returns information about the PutBucketAnalyticsConfigurationResponse response metadata. The PutBucketAnalyticsConfigurationResponse operation has a void result type.

The configuration information for a bucket

Container for the parameters to the PutBucketEncryption operation.

This operation is not supported by directory buckets.

This action uses the encryption subresource to configure default encryption and Amazon S3 Bucket Keys for an existing bucket.

By default, all buckets have a default encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). You can optionally configure default encryption for a bucket by using server-side encryption with Key Management Service (KMS) keys (SSE-KMS) or dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS). If you specify default encryption by using SSE-KMS, you can also configure Amazon S3 Bucket Keys. If you use PutBucketEncryption to set your default bucket encryption to SSE-KMS, you should verify that your KMS key ID is correct. Amazon S3 does not validate the KMS key ID provided in PutBucketEncryption requests.

To use this operation, you must have permission to perform the s3:PutEncryptionConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

The following operations are related to PutBucketEncryption:

• GetBucketEncryption

• DeleteBucketEncryption

Container for the parameters to the PutBucketIntelligentTieringConfiguration operation.

This operation is not supported by directory buckets.

Puts a S3 Intelligent-Tiering configuration to the specified bucket. You can have up to 1,000 S3 Intelligent-Tiering configurations per bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

Operations related to PutBucketIntelligentTieringConfiguration include:

• DeleteBucketIntelligentTieringConfiguration

• GetBucketIntelligentTieringConfiguration

• ListBucketIntelligentTieringConfigurations

PutBucketIntelligentTieringConfiguration has the following special errors:

HTTP 400 Bad Request Error

Code: InvalidArgument

Cause: Invalid Argument

HTTP 400 Bad Request Error

Code: TooManyConfigurations

Cause: You are attempting to create a new configuration but have already reached the 1,000-configuration limit.

HTTP 403 Forbidden Error

Cause: You are not the owner of the specified bucket, or you do not have the s3:PutIntelligentTieringConfiguration bucket permission to set the configuration on the bucket.

Returns information about the PutBucketIntelligentTieringConfiguration response metadata. The PutBucketIntelligentTieringConfiguration operation has a void result type.

Container for the parameters to the PutBucketInventoryConfiguration operation.

This operation is not supported by directory buckets.

This implementation of the PUT action adds an inventory configuration (identified by the inventory ID) to the bucket. You can have up to 1,000 inventory configurations per bucket.

Amazon S3 inventory generates inventories of the objects in the bucket on a daily or weekly basis, and the results are published to a flat file. The bucket that is inventoried is called the source bucket, and the bucket where the inventory flat file is stored is called the destination bucket. The destination bucket must be in the same Amazon Web Services Region as the source bucket.

When you configure an inventory for a source bucket, you specify the destination bucket where you want the inventory to be stored, and whether to generate the inventory daily or weekly. You can also configure what object metadata to include and whether to inventory all object versions or only current versions. For more information, see Amazon S3 Inventory in the Amazon S3 User Guide.

Permissions

To use this operation, you must have permission to perform the s3:PutInventoryConfiguration action. The bucket owner has this permission by default and can grant this permission to others.

The s3:PutInventoryConfiguration permission allows a user to create an S3 Inventory report that includes all object metadata fields available and to specify the destination bucket to store the inventory. A user with read access to objects in the destination bucket can also access all object metadata fields that are available in the inventory report.

To restrict access to an inventory report, see Restricting access to an Amazon S3 Inventory report in the Amazon S3 User Guide. For more information about the metadata fields available in S3 Inventory, see Amazon S3 Inventory lists in the Amazon S3 User Guide. For more information about permissions, see Permissions related to bucket subresource operations and Identity and access management in Amazon S3 in the Amazon S3 User Guide.

Returns information about the PutInventoryConfigurationResponse response metadata. The PutInventoryConfigurationResponse operation has a void result type.

Container for the parameters to the PutBucketLogging operation.

This operation is not supported by directory buckets.

Set the logging parameters for a bucket and to specify permissions for who can view and modify the logging parameters. All logs are saved to buckets in the same Amazon Web Services Region as the source bucket. To set the logging status of a bucket, you must be the bucket owner.

The bucket owner is automatically granted FULL_CONTROL to all logs. You use the Grantee request element to grant access to other people. The Permissions request element specifies the kind of access the grantee has to the logs.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (by using request elements) in the following ways:

• By the person's ID:

  <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName>
              </Grantee>
  

  DisplayName is optional and ignored in the request.

• By Email address:

  <>Grantees@email.com<>

  The grantee is resolved to the CanonicalUser and, in a response to a GETObjectAcl request, appears as the CanonicalUser.

• By URI:

  <>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<>

To enable logging, you use LoggingEnabled and its children request elements. To disable logging, you use an empty BucketLoggingStatus request element:

For more information about server access logging, see Server Access Logging in the Amazon S3 User Guide.

For more information about creating a bucket, see CreateBucket. For more information about returning the logging status of a bucket, see GetBucketLogging.

The following operations are related to PutBucketLogging:

• GetBucketLogging

Returns information about the PutBucketLogging response metadata. The EnableBucketLogging operation has a void result type.

Container for the parameters to the PutBucketMetricsConfiguration operation.

This operation is not supported by directory buckets.

Sets a metrics configuration (specified by the metrics configuration ID) for the bucket. You can have up to 1,000 metrics configurations per bucket. If you're updating an existing metrics configuration, note that this is a full replacement of the existing metrics configuration. If you don't include the elements you want to keep, they are erased.

To use this operation, you must have permissions to perform the s3:PutMetricsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

For information about CloudWatch request metrics for Amazon S3, see Monitoring Metrics with Amazon CloudWatch.

The following operations are related to PutBucketMetricsConfiguration:

• GetBucketMetricsConfiguration

• ListBucketMetricsConfigurations

PutBucketMetricsConfiguration has the following special error:

• Error code: TooManyConfigurations

  • Description: You are attempting to create a new configuration but have already reached the 1,000-configuration limit.

  • HTTP Status Code: HTTP 400 Bad Request

Returns information about the PutBucketMetricsConfiguration response metadata. The PutBucketMetricsConfiguration operation has a void result type.

Container for the parameters to the PutBucketNotification operation.

This operation is not supported by directory buckets.

Enables notifications of specified events for a bucket. For more information about event notifications, see Configuring Event Notifications.

Using this API, you can replace an existing notification configuration. The configuration is an XML file that defines the event types that you want Amazon S3 to publish and the destination where you want Amazon S3 to publish an event notification when it detects an event of the specified type.

By default, your bucket has no event notifications configured. That is, the notification configuration will be an empty NotificationConfiguration.

This action replaces the existing notification configuration with the configuration you include in the request body.

After Amazon S3 receives this request, it first verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner has permission to publish to it by sending a test notification. In the case of Lambda destinations, Amazon S3 verifies that the Lambda function permissions grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For more information, see Configuring Notifications for Amazon S3 Events.

You can disable notifications by adding the empty NotificationConfiguration element.

For more information about the number of event notification configurations that you can create per bucket, see Amazon S3 service quotas in Amazon Web Services General Reference.

By default, only the bucket owner can configure notifications on a bucket. However, bucket owners can use a bucket policy to grant permission to other users to set this configuration with the required s3:PutBucketNotification permission.

If the configuration in the request body includes only one TopicConfiguration specifying only the s3:ReducedRedundancyLostObject event type, the response will also include the x-amz-sns-test-message-id header containing the message ID of the test notification sent to the topic.

The following action is related to PutBucketNotificationConfiguration:

• GetBucketNotificationConfiguration

Returns information about the PutBucketNotification response metadata. The PutBucketNotification operation has a void result type.

Container for the parameters to the PutBucketOwnershipControls operation.

This operation is not supported by directory buckets.

Creates or modifies OwnershipControls for an Amazon S3 bucket. To use this operation, you must have the s3:PutBucketOwnershipControls permission. For more information about Amazon S3 permissions, see Specifying permissions in a policy.

For information about Amazon S3 Object Ownership, see Using object ownership.

The following operations are related to PutBucketOwnershipControls:

• GetBucketOwnershipControls

• DeleteBucketOwnershipControls

Returns information about the PutBucketOwnershipControls response metadata. The PutBucketOwnershipControls operation has a void result type.

Container for the parameters to the PutBucketPolicy operation. Applies an Amazon S3 bucket policy to an Amazon S3 bucket.

Directory buckets - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format https://s3express-control.region_code.amazonaws.com/bucket-name. Virtual-hosted-style requests aren't supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the PutBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have PutBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

To ensure that bucket owners don't inadvertently lock themselves out of their own buckets, the root principal in a bucket owner's Amazon Web Services account can perform the GetBucketPolicy, PutBucketPolicy, and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal's access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

• General purpose bucket permissions - The s3:PutBucketPolicy permission is required in a policy. For more information about general purpose buckets bucket policies, see Using Bucket Policies and User Policies in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation, you must have the s3express:PutBucketPolicy permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

The following operations are related to PutBucketPolicy:

• CreateBucket

• DeleteBucket

Returns information about the PutBucketPolicy response metadata. The PutBucketPolicy operation has a void result type.

Container for the parameters to the PutBucketReplication operation.

This operation is not supported by directory buckets.

Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 User Guide.

Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket or buckets where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information. You can invoke this request for a specific Amazon Web Services Region by using the aws:RequestedRegion condition key.

A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset.

To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements: DeleteMarkerReplication, Status, and Priority.

For information about enabling versioning on a bucket, see Using Versioning.

Handling Replication of Encrypted Objects

By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with KMS keys. To replicate Amazon Web Services KMS-encrypted objects, add the following: SourceSelectionCriteria, SseKmsEncryptedObjects, Status, EncryptionConfiguration, and ReplicaKmsKeyID. For information about replication configuration, see Replicating Objects Created with SSE Using KMS keys.

For information on PutBucketReplication errors, see List of replication-related error codes

Permissions

To create a PutBucketReplication request, you must have s3:PutReplicationConfiguration permissions for the bucket.

By default, a resource owner, in this case the Amazon Web Services account that created the bucket, can perform this operation. The resource owner can also grant others permissions to perform the operation. For more information about permissions, see Specifying Permissions in a Policy and Managing Access Permissions to Your Amazon S3 Resources.

To perform this operation, the user or role performing the action must have the iam:PassRole permission.

The following operations are related to PutBucketReplication:

• GetBucketReplication

• DeleteBucketReplication

Returns information about the PutBucketReplicationConfiguration response metadata. The PutBucketReplicationConfiguration operation has a void result type.

Container for the parameters to the PutBucket operation.

This action creates an Amazon S3 bucket. To create an Amazon S3 on Outposts bucket, see CreateBucket.

Creates a new S3 bucket. To create a bucket, you must set up Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.

There are two types of buckets: general purpose buckets and directory buckets. For more information about these bucket types, see Creating, configuring, and working with Amazon S3 buckets in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - In addition to the s3:CreateBucket permission, the following permissions are required in a policy when your CreateBucket request includes specific headers:

  • Access control lists (ACLs) - In your CreateBucket request, if you specify an access control list (ACL) and set it to public-read, public-read-write, authenticated-read, or if you explicitly specify any other custom ACLs, both s3:CreateBucket and s3:PutBucketAcl permissions are required. In your CreateBucket request, if you set the ACL to private, or if you don't specify any ACLs, only the s3:CreateBucket permission is required.

  • Object Lock - In your CreateBucket request, if you set x-amz-bucket-object-lock-enabled to true, the s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.

  • S3 Object Ownership - If your CreateBucket request includes the x-amz-object-ownership header, then the s3:PutBucketOwnershipControls permission is required.

    To set an ACL on a bucket as part of a CreateBucket request, you must explicitly set S3 Object Ownership for the bucket to a different value than the default, BucketOwnerEnforced. Additionally, if your desired bucket ACL grants public access, you must first create the bucket (without the bucket ACL) and then explicitly disable Block Public Access on the bucket before using PutBucketAcl to set the ACL. If you try to create a bucket with a public ACL, the request will fail.

    For the majority of modern use cases in S3, we recommend that you keep all Block Public Access settings enabled and keep ACLs disabled. If you would like to share data with users outside of your account, you can use bucket policies as needed. For more information, see Controlling ownership of objects and disabling ACLs for your bucket and Blocking public access to your Amazon S3 storage in the Amazon S3 User Guide.

  • S3 Block Public Access - If your specific use case requires granting public access to your S3 resources, you can disable Block Public Access. Specifically, you can create a new bucket with Block Public Access enabled, then separately call the DeletePublicAccessBlock API. To use this operation, you must have the s3:PutBucketPublicAccessBlock permission. For more information about S3 Block Public Access, see Blocking public access to your Amazon S3 storage in the Amazon S3 User Guide.

• Directory bucket permissions - You must have the s3express:CreateBucket permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

  The permissions for ACLs, Object Lock, S3 Object Ownership, and S3 Block Public Access are not supported for directory buckets. For directory buckets, all Block Public Access settings are enabled at the bucket level and S3 Object Ownership is set to Bucket owner enforced (ACLs disabled). These settings can't be modified.

  For more information about permissions for creating and working with directory buckets, see Directory buckets in the Amazon S3 User Guide. For more information about supported S3 features for directory buckets, see Features of S3 Express One Zone in the Amazon S3 User Guide.

Container for the parameters to the PutBucketTagging operation.

This operation is not supported by directory buckets.

Sets the tags for a bucket.

Use tags to organize your Amazon Web Services bill to reflect your own cost structure. To do this, sign up to get your Amazon Web Services account bill with tag key values included. Then, to see the cost of combined resources, organize your billing information according to resources with the same tag key values. For example, you can tag several resources with a specific application name, and then organize your billing information to see the total cost of that application across several services. For more information, see Cost Allocation and Tagging and Using Cost Allocation in Amazon S3 Bucket Tags.

To use this operation, you must have permissions to perform the s3:PutBucketTagging action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

PutBucketTagging has the following special errors. For more Amazon S3 errors see, Error Responses.

• InvalidTag - The tag provided was not a valid tag. This error can occur if the tag did not pass input validation. For more information, see Using Cost Allocation in Amazon S3 Bucket Tags.

• MalformedXML - The XML provided does not match the schema.

• OperationAborted - A conflicting conditional action is currently in progress against this resource. Please try again.

• InternalError - The service was unable to apply the provided tag to the bucket.

The following operations are related to PutBucketTagging:

• GetBucketTagging

• DeleteBucketTagging

Returns information about the PutBucketTagging response metadata. The PutBucketTagging operation has a void result type.

Container for the parameters to the PutBucketVersioning operation.

This operation is not supported by directory buckets.

Sets the versioning state of an existing bucket.

You can set the versioning state with one of the following values:

Enabled�Enables versioning for the objects in the bucket. All objects added to the bucket receive a unique version ID.

Suspended�Disables versioning for the objects in the bucket. All objects added to the bucket receive the version ID null.

If the versioning state has never been set on a bucket, it has no versioning state; a GetBucketVersioning request does not return a versioning state value.

In order to enable MFA Delete, you must be the bucket owner. If you are the bucket owner and want to enable MFA Delete in the bucket versioning configuration, you must include the x-amz-mfa request header and the Status and the MfaDelete request elements in a request to set the versioning state of the bucket.

The following operations are related to PutBucketVersioning:

• CreateBucket

• DeleteBucket

• GetBucketVersioning

Returns information about the PutBucketVersioning response metadata. The PutBucketVersioning operation has a void result type.

Container for the parameters to the PutBucketWebsite operation.

This operation is not supported by directory buckets.

Sets the configuration of the website that is specified in the website subresource. To configure a bucket as a website, you can add this subresource on the bucket with website configuration information such as the file name of the index document and any redirect rules. For more information, see Hosting Websites on Amazon S3.

This PUT action requires the S3:PutBucketWebsite permission. By default, only the bucket owner can configure the website attached to a bucket; however, bucket owners can allow other users to set the website configuration by writing a bucket policy that grants them the S3:PutBucketWebsite permission.

To redirect all website requests sent to the bucket's website endpoint, you add a website configuration with the following elements. Because all requests are sent to another website, you don't need to provide index document name for the bucket.

• WebsiteConfiguration

• RedirectAllRequestsTo

• HostName

• Protocol

If you want granular control over redirects, you can use the following elements to add routing rules that describe conditions for redirecting requests and information about the redirect destination. In this case, the website configuration must provide an index document for the bucket, because some requests might not be redirected.

• WebsiteConfiguration

• IndexDocument

• Suffix

• ErrorDocument

• Key

• RoutingRules

• RoutingRule

• Condition

• HttpErrorCodeReturnedEquals

• KeyPrefixEquals

• Redirect

• Protocol

• HostName

• ReplaceKeyPrefixWith

• ReplaceKeyWith

• HttpRedirectCode

Amazon S3 has a limitation of 50 routing rules per website configuration. If you require more than 50 routing rules, you can use object redirect. For more information, see Configuring an Object Redirect in the Amazon S3 User Guide.

The maximum request length is limited to 128 KB.

Returns information about the PutBucketWebsite response metadata. The PutBucketWebsite operation has a void result type.

Container for the parameters to the PutCORSConfiguration operation.

This operation is not supported by directory buckets.

Sets the cors configuration for your bucket. If the configuration exists, Amazon S3 replaces it.

To use this operation, you must be allowed to perform the s3:PutBucketCORS action. By default, the bucket owner has this permission and can grant it to others.

You set this configuration on a bucket so that the bucket can service cross-origin requests. For example, you might want to enable a request whose origin is http://www.example.com to access your Amazon S3 bucket at amzn-s3-demo-bucket by using the browser's XMLHttpRequest capability.

To enable cross-origin resource sharing (CORS) on a bucket, you add the cors subresource to the bucket. The cors subresource is an XML document in which you configure rules that identify origins and the HTTP methods that can be executed on your bucket. The document is limited to 64 KB in size.

When Amazon S3 receives a cross-origin request (or a pre-flight OPTIONS request) against a bucket, it evaluates the cors configuration on the bucket and uses the first CORSRule rule that matches the incoming browser request to enable a cross-origin request. For a rule to match, the following conditions must be met:

• The request's Origin header must match AllowedOrigin elements.

• The request method (for example, GET, PUT, HEAD, and so on) or the Access-Control-Request-Method header in case of a pre-flight OPTIONS request must be one of the AllowedMethod elements.

• Every header specified in the Access-Control-Request-Headers request header of a pre-flight request must match an AllowedHeader element.

For more information about CORS, go to Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide.

The following operations are related to PutBucketCors:

• GetBucketCors

• DeleteBucketCors

• RESTOPTIONSobject

Returns information about the PutCORSConfiguration response metadata. The PutCORSConfiguration operation has a void result type.

Container for the parameters to the PutLifecycleConfiguration operation.

This operation is not supported by directory buckets.

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. Keep in mind that this will overwrite an existing lifecycle configuration, so if you want to retain any configuration details, they must be included in the new lifecycle configuration. For information about lifecycle configuration, see Managing your storage lifecycle.

Rules

You specify the lifecycle configuration in your request body. The lifecycle configuration is specified as XML consisting of one or more rules. An Amazon S3 Lifecycle configuration can have up to 1,000 rules. This limit is not adjustable. Each rule consists of the following:

• A filter identifying a subset of objects to which the rule applies. The filter can be based on a key name prefix, object tags, object size, or any combination of these.

• A status indicating whether the rule is in effect.

• One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.

For more information, see Object Lifecycle Management and Lifecycle Configuration Elements.

Permissions

By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the s3:PutLifecycleConfiguration permission.

You can also explicitly deny permissions. An explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

• s3:DeleteObject

• s3:DeleteObjectVersion

• s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources.

The following operations are related to PutBucketLifecycleConfiguration:

• Examples of Lifecycle Configuration

• GetBucketLifecycleConfiguration

• DeleteBucketLifecycle

Returns information about the PutLifecycleConfiguration response metadata. The PutLifecycleConfiguration operation has a void result type.

Container for the parameters to the PutObjectLegalHold operation.

This operation is not supported by directory buckets.

Applies a legal hold configuration to the specified object. For more information, see Locking Objects.

This functionality is not supported for Amazon S3 on Outposts.

This is the response object from the PutObjectLegalHold operation.

Container for the parameters to the PutObjectLockConfiguration operation.

This operation is not supported by directory buckets.

Places an Object Lock configuration on the specified bucket. The rule specified in the Object Lock configuration will be applied by default to every new object placed in the specified bucket. For more information, see Locking Objects.

This is the response object from the PutObjectLockConfiguration operation.

Container for the parameters to the PutObject operation. Adds an object to a bucket.

• Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket. You cannot use PutObject to only update a single piece of metadata for an existing object. You must put the entire object with updated metadata if you want to update some values.

• If your bucket uses the bucket owner enforced setting for Object Ownership, ACLs are disabled and no longer affect permissions. All objects written to the bucket by any account will be owned by the bucket owner.

• Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. However, Amazon S3 provides features that can modify this behavior:

• S3 Object Lock - To prevent objects from being deleted or overwritten, you can use Amazon S3 Object Lock in the Amazon S3 User Guide.

  This functionality is not supported for directory buckets.

• S3 Versioning - When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all versions of the objects. For each write request that is made to the same object, Amazon S3 automatically generates a unique version ID of that object being stored in Amazon S3. You can retrieve, replace, or delete any version of the object. For more information about versioning, see Adding Objects to Versioning-Enabled Buckets in the Amazon S3 User Guide. For information about returning the versioning state of a bucket, see GetBucketVersioning.

  This functionality is not supported for directory buckets.

Permissions

• General purpose bucket permissions - The following permissions are required in your policies when your PutObject request includes specific headers.

  • s3:PutObject - To successfully complete the PutObject request, you must always have the s3:PutObject permission on a bucket to add an object to it.

  • s3:PutObjectAcl - To successfully change the objects ACL of your PutObject request, you must have the s3:PutObjectAcl.

  • s3:PutObjectTagging - To successfully set the tag-set with your PutObject request, you must have the s3:PutObjectTagging.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Data integrity with Content-MD5

• General purpose bucket - To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, Amazon S3 returns an error. Alternatively, when the object's ETag is its MD5 digest, you can calculate the MD5 while putting the object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

• Directory bucket - This functionality is not supported for directory buckets.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

For more information about related Amazon S3 APIs, see the following:

• CopyObject

• DeleteObject

Returns information about the PutObject response and response metadata.

Container for the parameters to the PutObjectRetention operation.

This operation is not supported by directory buckets.

Places an Object Retention configuration on an object. For more information, see Locking Objects. Users or accounts require the s3:PutObjectRetention permission in order to place an Object Retention configuration on objects. Bypassing a Governance Retention configuration requires the s3:BypassGovernanceRetention permission.

This functionality is not supported for Amazon S3 on Outposts.

This is the response object from the PutObjectRetention operation.

Container for the parameters to the PutObjectTagging operation.

This operation is not supported by directory buckets.

Sets the supplied tag-set to an object that already exists in a bucket. A tag is a key-value pair. For more information, see Object Tagging.

You can associate tags with an object by sending a PUT request against the tagging subresource that is associated with the object. You can retrieve tags by sending a GET request. For more information, see GetObjectTagging.

For tagging-related restrictions related to characters and encodings, see Tag Restrictions. Note that Amazon S3 limits the maximum number of tags to 10 tags per object.

To use this operation, you must have permission to perform the s3:PutObjectTagging action. By default, the bucket owner has this permission and can grant this permission to others.

To put tags of any other version, use the versionId query parameter. You also need permission for the s3:PutObjectVersionTagging action.

PutObjectTagging has the following special errors. For more Amazon S3 errors see, Error Responses.

• InvalidTag - The tag provided was not a valid tag. This error can occur if the tag did not pass input validation. For more information, see Object Tagging.

• MalformedXML - The XML provided does not match the schema.

• OperationAborted - A conflicting conditional action is currently in progress against this resource. Please try again.

• InternalError - The service was unable to apply the provided tag to the object.

The following operations are related to PutObjectTagging:

• GetObjectTagging

• DeleteObjectTagging

Returns information about the PutObjectTagging response and response metadata.

Container for the parameters to the PutPublicAccessBlock operation.

This operation is not supported by directory buckets.

Creates or modifies the PublicAccessBlock configuration for an Amazon S3 bucket. To use this operation, you must have the s3:PutBucketPublicAccessBlock permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy.

For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public".

The following operations are related to PutPublicAccessBlock:

• GetPublicAccessBlock

• DeletePublicAccessBlock

• GetBucketPolicyStatus

• Using Amazon S3 Block Public Access

This is the response object from the PutPublicAccessBlock operation.

Base class for put operations that can also put an ACL.

This class contains the configuration Amazon S3 uses to figure out what events you want to listen and send the event to an Amazon SQS queue.

The queue's policy must allow S3 to send messages to it. The utility method Amazon.SQS.AmazonSQSClient.AuthorizeS3ToSendMessage(string,string) can be used to help setup the queue policy.

The Records Event

A filter that you can specify for selection for modifications on replicas. Amazon S3 doesn't replicate replica modifications by default. In the latest version of replication configuration (when Filter is specified), you can specify this element and set the status to Enabled to replicate modifications on replicas.

This class defines the configuration for replication.

Specifies information about where to publish analysis or configuration results for an Amazon S3 bucket and S3 Replication Time Control (S3 RTC).

Rule that specifies the replication configuration.

Filter that identifies subset of objects to which the replication rule applies. A Filter must specify exactly one Prefix, Tag, or an And child element.

Container for values of the response headers that will be set on a response from a GetObject request. These values override any headers that were set when the object was uploaded to S3.

Container for the parameters to the RestoreObject operation.

This operation is not supported by directory buckets.

Restores an archived copy of an object back into Amazon S3

This functionality is not supported for Amazon S3 on Outposts.

This action performs the following types of requests:

• restore an archive - Restore an archived object

For more information about the S3 structure in the request body, see the following:

• PutObject

• Managing Access with ACLs in the Amazon S3 User Guide

• Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide

Permissions

To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

Restoring objects

Objects that you archive to the S3 Glacier Flexible Retrieval Flexible Retrieval or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, are not accessible in real time. For objects in the S3 Glacier Flexible Retrieval Flexible Retrieval or S3 Glacier Deep Archive storage classes, you must first initiate a restore request, and then wait until a temporary copy of the object is available. If you want a permanent copy of the object, create a copy of it in the Amazon S3 Standard storage class in your S3 bucket. To access an archived object, you must restore the object for the duration (number of days) that you specify. For objects in the Archive Access or Deep Archive Access tiers of S3 Intelligent-Tiering, you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier.

To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.

When restoring an archived object, you can specify one of the following data access tier options in the Tier element of the request body:

• Expedited - Expedited retrievals allow you to quickly access your data stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering Archive tier when occasional urgent requests for restoring archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals is typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.

• Standard - Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for retrieval requests that do not specify the retrieval option. Standard retrievals typically finish within 3–5 hours for objects stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.

• Bulk - Bulk retrievals free for objects stored in the S3 Glacier Flexible Retrieval and S3 Intelligent-Tiering storage classes, enabling you to retrieve large amounts, even petabytes, of data at no cost. Bulk retrievals typically finish within 5–12 hours for objects stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering Archive tier. Bulk retrievals are also the lowest-cost retrieval option when restoring objects from S3 Glacier Deep Archive. They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.

For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon S3 User Guide.

You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide.

To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon S3 User Guide.

After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.

If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon S3 User Guide.

Responses

A successful action returns either the 200 OK or 202 Accepted status code.

• If the object is not previously restored, then Amazon S3 returns 202 Accepted in the response.

• If the object is previously restored, Amazon S3 returns 200 OK in the response.

• Special errors:

  • Code: RestoreAlreadyInProgress

  • Cause: Object restore is already in progress.

  • HTTP Status Code: 409 Conflict

  • SOAP Fault Code Prefix: Client

• • Code: GlacierExpeditedRetrievalNotAvailable

  • Cause: expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to S3 Standard or Bulk retrievals.)

  • HTTP Status Code: 503

  • SOAP Fault Code Prefix: N/A

The following operations are related to RestoreObject:

• PutBucketLifecycleConfiguration

• GetBucketNotificationConfiguration

Returns information about the RestoreObject response metadata. The RestoreObject operation has a void result type.

Specifies the restoration status of an object. Objects in certain storage classes must be restored before they can be retrieved. For more information about these storage classes and how to work with archived objects, see Working with archived objects in the Amazon S3 User Guide.

This functionality is not supported for directory buckets. Only the S3 Express One Zone storage class is supported by directory buckets to store objects.

Routing Rule

A container for describing a condition that must be met for the specified redirect to apply. For example, 1. If request is for pages in the /docs folder, redirect to the /documents folder. 2. If request results in HTTP error 4xx, redirect request to another host where you might process the error.

Container for redirect information. You can redirect requests to another host, to another page, or with another protocol. In the event of an error, you can can specify a different error code to return.

Represents an access control list (ACL) for S3. An AccessControlList is represented by an Owner, and a List of Grants, where each Grant is a Grantee and a Permission.

In terms of implementation, a Bucket is a resource. An Amazon S3 bucket name is globally unique, and the namespace is shared by all Amazon Web Services accounts.

Describes where logs are stored and the prefix that Amazon S3 assigns to all log object keys for a bucket. For more information, see PUT Bucket logging in the Amazon S3 API Reference.

Describes the versioning state of an Amazon S3 bucket. For more information, see PUT Bucket versioning in the Amazon S3 API Reference.

Describes the server-side encryption that will be applied to the restore results.

Modeled Exception that either comes over the stream from the service model, or wraps other exceptions for the purpose of raising events. If it is modelled, it will be a subclass.

Container for granting information.

Buckets that use the bucket owner enforced setting for Object Ownership don't support target grants. For more information, see Permissions server access log delivery in the Amazon S3 User Guide.

Grantee

Filter criteria that allows for event notification filtering based on an S3 Object's key name.

The specified metadata table name must be unique within the aws_s3_metadata namespace in the destination table bucket.

The destination information for the metadata table configuration. The destination table bucket must be in the same Region and Amazon Web Services account as the general purpose bucket. The specified metadata table name must be unique within the aws_s3_metadata namespace in the destination table bucket.

Specifies the byte range of the object to get the records from. A record is processed when its first byte is contained by the range.

A Stream of Events returned by the SelectObjectContent operation. Events can be retrieved from this stream by either attaching handlers to listen events, and then call StartProcessing orenumerating over the events.

These options should be treaded as mutually exclusive.

Container for the parameters to the SelectObjectContent operation.

This operation is not supported by directory buckets.

This action filters the contents of an Amazon S3 object based on a simple structured query language (SQL) statement. In the request, along with the SQL expression, you must also specify a data serialization format (JSON, CSV, or Apache Parquet) of the object. Amazon S3 uses this format to parse object data into records, and returns only records that match the specified SQL expression. You must also specify the data serialization format for the response.

This functionality is not supported for Amazon S3 on Outposts.

For more information about Amazon S3 Select, see Selecting Content from Objects and SELECT Command in the Amazon S3 User Guide.

Permissions

You must have the s3:GetObject permission for this operation. Amazon S3 Select does not support anonymous access. For more information about permissions, see Specifying Permissions in a Policy in the Amazon S3 User Guide.

Object Data Formats

You can use Amazon S3 Select to query objects that have the following format properties:

• CSV, JSON, and Parquet - Objects must be in CSV, JSON, or Parquet format.

• UTF-8 - UTF-8 is the only encoding type Amazon S3 Select supports.

• GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP or BZIP2. GZIP and BZIP2 are the only compression formats that Amazon S3 Select supports for CSV and JSON files. Amazon S3 Select supports columnar compression for Parquet using GZIP or Snappy. Amazon S3 Select does not support whole-object compression for Parquet objects.

• Server-side encryption - Amazon S3 Select supports querying objects that are protected with server-side encryption.

  For objects that are encrypted with customer-provided encryption keys (SSE-C), you must use HTTPS, and you must use the headers that are documented in the GetObject. For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.

  For objects that are encrypted with Amazon S3 managed keys (SSE-S3) and Amazon Web Services KMS keys (SSE-KMS), server-side encryption is handled transparently, so you don't need to specify anything. For more information about server-side encryption, including SSE-S3 and SSE-KMS, see Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide.

Working with the Response Body

Given the response size is unknown, Amazon S3 Select streams the response as a series of messages and includes a Transfer-Encoding header with chunked as its value in the response. For more information, see Appendix: SelectObjectContent Response.

GetObject Support

The SelectObjectContent action does not support the following GetObject functionality. For more information, see GetObject.

• Range: Although you can specify a scan range for an Amazon S3 Select request (see SelectObjectContentRequest - ScanRange in the request parameters), you cannot specify the range of bytes of an object to return.

• The GLACIER, DEEP_ARCHIVE, and REDUCED_REDUNDANCY storage classes, or the ARCHIVE_ACCESS and DEEP_ARCHIVE_ACCESS access tiers of the INTELLIGENT_TIERING storage class: You cannot query objects in the GLACIER, DEEP_ARCHIVE, or REDUCED_REDUNDANCY storage classes, nor objects in the ARCHIVE_ACCESS or DEEP_ARCHIVE_ACCESS access tiers of the INTELLIGENT_TIERING storage class. For more information about storage classes, see Using Amazon S3 storage classes in the Amazon S3 User Guide.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without additional operational overhead.

Too many parts exception

This class contains the configuration Amazon S3 uses to figure out what events you want to listen and send the event to an Amazon SNS topic.

The topic's policy must allow S3 to publish messages to it. The utility method Amazon.SimpleNotificationService.AmazonSimpleNotificationServiceClient.AuthorizeS3ToPublish(string,string) can be used to help setup the topic policy.

Arguments containing event details for an in-flight transfer.

This Event is returned if an event is retrieved from the event stream, but a generator function for the event is not defined.

Container for the parameters to the UploadPart operation. Uploads a part in a multipart upload.

In this operation, you provide new data as a part of an object in your request. However, you have an option to specify your existing Amazon S3 object as a data source for the part you are uploading. To upload a part from an existing object, you use the UploadPartCopy operation.

You must initiate a multipart upload (see CreateMultipartUpload) before you can upload any part. In response to your initiate request, Amazon S3 returns an upload ID, a unique identifier that you must include in your upload part request.

Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being created. If you upload a new part using the same part number that was used with a previous part, the previously uploaded part is overwritten.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide.

For more information on multipart uploads, go to Multipart Upload Overview in the Amazon S3 User Guide .

Permissions

• General purpose bucket permissions - For information on the permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

Data integrity

General purpose bucket - To ensure that data is not corrupted traversing the network, specify the Content-MD5 header in the upload part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error. If the upload request is signed with Signature Version 4, then Amazon Web Services S3 uses the x-amz-content-sha256 header as a checksum instead of Content-MD5. For more information see Authenticating Requests: Using the Authorization Header (Amazon Web Services Signature Version 4).

Directory buckets - MD5 is not supported by directory buckets. You can use checksum algorithms to check object integrity.

Encryption

• General purpose bucket - Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You have mutually exclusive options to protect data using server-side encryption in Amazon S3, depending on how you choose to manage the encryption keys. Specifically, the encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS), and Customer-Provided Keys (SSE-C). Amazon S3 encrypts data with server-side encryption using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption with other key options. The option you use depends on whether you want to use KMS keys (SSE-KMS) or provide your own encryption key (SSE-C).

  Server-side encryption is supported by the S3 Multipart Upload operations. Unless you are using a customer-provided encryption key (SSE-C), you don't need to specify the encryption parameters in each UploadPart request. Instead, you only need to specify the server-side encryption parameters in the initial Initiate Multipart request. For more information, see CreateMultipartUpload.

  If you request server-side encryption using a customer-provided encryption key (SSE-C) in your initiate multipart upload request, you must provide identical encryption information in each part upload using the following request headers.

  • x-amz-server-side-encryption-customer-algorithm

  • x-amz-server-side-encryption-customer-key

  • x-amz-server-side-encryption-customer-key-MD5

• Directory bucket - For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

For more information, see Using Server-Side Encryption in the Amazon S3 User Guide.

Special errors

• Error Code: NoSuchUpload

  • Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.

  • HTTP Status Code: 404 Not Found

  • SOAP Fault Code Prefix: Client

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

The following operations are related to UploadPart:

• CreateMultipartUpload

• CompleteMultipartUpload

• AbortMultipartUpload

• ListParts

• ListMultipartUploads

Returns information about the UploadPart response and response metadata.

Website Configuration

Container for the parameters to the WriteGetObjectResponse operation.

This operation is not supported by directory buckets.

Passes transformed objects to a GetObject operation when using Object Lambda access points. For information about Object Lambda access points, see Transforming objects with Object Lambda access points in the Amazon S3 User Guide.

This operation supports metadata that can be returned by GetObject, in addition to RequestRoute, RequestToken, StatusCode, ErrorCode, and ErrorMessage. The GetObject response metadata is supported so that the WriteGetObjectResponse caller, typically an Lambda function, can provide the same metadata when it internally invokes GetObject. When WriteGetObjectResponse is called by a customer-owned Lambda function, the metadata returned to the end user GetObject call might differ from what Amazon S3 would normally return.

You can include any number of metadata headers. When including a metadata header, it should be prefaced with x-amz-meta. For example,

x-amz-meta-my-custom-header:
            MyCustomValue

Amazon Web Services provides some prebuilt Lambda functions that you can use with S3 Object Lambda to detect and redact personally identifiable information (PII) and decompress S3 objects. These Lambda functions are available in the Amazon Web Services Serverless Application Repository, and can be selected through the Amazon Web Services Management Console when you create your Object Lambda access point.

Example 1: PII Access Control - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically detects personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 2: PII Redaction - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically redacts personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is equipped to decompress objects stored in S3 in one of six compressed file formats including bzip2, gzip, snappy, zlib, zstandard and ZIP.

For information on how to view and use these functions, see Using Amazon Web Services built Lambda functions in the Amazon S3 User Guide.
