PutObject - Amazon Simple Storage Service

PutObject

Adds an object to a bucket.

Note
  • 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.

    Note

    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.

    Note

    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. AWS 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.

URI Request Parameters

The request uses the following URI parameters.

Bucket

The bucket name to which the PUT action was initiated.

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.

Note

Access points and Object Lambda access points are not supported by directory buckets.

S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the AWS SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

Required: Yes

Cache-Control

Can be used to specify caching behavior along the request/reply chain. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.

Content-Disposition

Specifies presentational information for the object. For more information, see https://www.rfc-editor.org/rfc/rfc6266#section-4.

Content-Encoding

Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#field.content-encoding.

Content-Language

The language the content is in.

Content-Length

Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-length.

Content-MD5

The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see REST Authentication.

Note

The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide.

Note

This functionality is not supported for directory buckets.

Content-Type

A standard MIME type describing the format of the contents. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-type.

Expires

The date and time at which the object is no longer cacheable. For more information, see https://www.rfc-editor.org/rfc/rfc7234#section-5.3.

Key

Object key for which the PUT action was initiated.

Length Constraints: Minimum length of 1.

Required: Yes

x-amz-acl

The canned ACL to apply to the object. For more information, see Canned ACL in the Amazon S3 User Guide.

When adding a new object, you can use headers to grant ACL-based permissions to individual AWS accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. By default, all objects are private. Only the owner has full access control. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API in the Amazon S3 User Guide.

If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain AWS accounts) fail and return a 400 error with the error code AccessControlListNotSupported. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

Note
  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

Valid Values: private | public-read | public-read-write | authenticated-read | aws-exec-read | bucket-owner-read | bucket-owner-full-control

x-amz-checksum-crc32

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

x-amz-checksum-crc32c

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32C checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

x-amz-checksum-sha1

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

x-amz-checksum-sha256

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

x-amz-expected-bucket-owner

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

x-amz-grant-full-control

Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

Note
  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

x-amz-grant-read

Allows grantee to read the object data and its metadata.

Note
  • This functionality is not supported for directory buckets.

Note
  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

x-amz-object-lock-legal-hold

Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see Object Lock in the Amazon S3 User Guide.

Note

This functionality is not supported for directory buckets.

Valid Values: ON | OFF

x-amz-object-lock-mode

The Object Lock mode that you want to apply to this object.

Note

This functionality is not supported for directory buckets.

Valid Values: GOVERNANCE | COMPLIANCE

x-amz-object-lock-retain-until-date

The date and time when you want this object's Object Lock to expire. Must be formatted as a timestamp parameter.

Note

This functionality is not supported for directory buckets.

x-amz-request-payer

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

Note

This functionality is not supported for directory buckets.

Valid Values: requester

x-amz-sdk-checksum-algorithm

Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum-algorithm or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request.

For the x-amz-checksum-algorithm header, replace algorithm with the supported algorithm from the following list:

  • CRC32

  • CRC32C

  • SHA1

  • SHA256

For more information, see Checking object integrity in the Amazon S3 User Guide.

If the individual checksum value you provide through x-amz-checksum-algorithm doesn't match the checksum algorithm you set through x-amz-sdk-checksum-algorithm, Amazon S3 ignores any provided ChecksumAlgorithm parameter and uses the checksum algorithm that matches the provided value in x-amz-checksum-algorithm .

Note

For directory buckets, when you use AWS SDKs, CRC32 is the default checksum algorithm that's used for performance.

Valid Values: CRC32 | CRC32C | SHA1 | SHA256

x-amz-server-side-encryption

The server-side encryption algorithm that was used when you store this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse).

General purpose buckets - You have four 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), AWS KMS keys (SSE-KMS or DSSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at rest by using server-side encryption with other key options. For more information, see Using Server-Side Encryption in the Amazon S3 User Guide.

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

Valid Values: AES256 | aws:kms | aws:kms:dsse

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

If x-amz-server-side-encryption has a valid value of aws:kms or aws:kms:dsse, this header specifies the ID (Key ID, Key ARN, or Key Alias) of the AWS Key Management Service (AWS KMS) symmetric encryption customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms or x-amz-server-side-encryption:aws:kms:dsse, but do not provide x-amz-server-side-encryption-aws-kms-key-id, Amazon S3 uses the AWS managed key (aws/s3) to protect the data. If the KMS key does not exist in the same account that's issuing the command, you must use the full ARN and not just the ID.

Note

This functionality is not supported for directory buckets.

x-amz-server-side-encryption-bucket-key-enabled

Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS Key Management Service (AWS KMS) keys (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

Note

This functionality is not supported for directory buckets.

x-amz-server-side-encryption-context

Specifies the AWS KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value is stored as object metadata and automatically gets passed on to AWS KMS for future GetObject or CopyObject operations on this object. This value must be explicitly added during CopyObject operations.

Note

This functionality is not supported for directory buckets.

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

Specifies the algorithm to use when encrypting the object (for example, AES256).

Note

This functionality is not supported for directory buckets.

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

Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.

Note

This functionality is not supported for directory buckets.

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

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

Note

This functionality is not supported for directory buckets.

x-amz-storage-class

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide.

Note
  • For directory buckets, only the S3 Express One Zone storage class is supported to store newly created objects.

  • Amazon S3 on Outposts only uses the OUTPOSTS Storage Class.

Valid Values: STANDARD | REDUCED_REDUNDANCY | STANDARD_IA | ONEZONE_IA | INTELLIGENT_TIERING | GLACIER | DEEP_ARCHIVE | OUTPOSTS | GLACIER_IR | SNOW | EXPRESS_ONEZONE

x-amz-tagging

The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, "Key1=Value1")

Note

This functionality is not supported for directory buckets.

x-amz-website-redirect-location

If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata in the Amazon S3 User Guide.

In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

x-amz-website-redirect-location: /anotherPage.html

In the following example, the request header sets the object redirect to another website:

x-amz-website-redirect-location: http://www.example.com/

For more information about website hosting in Amazon S3, see Hosting Websites on Amazon S3 and How to Configure Website Page Redirects in the Amazon S3 User Guide.

Note

This functionality is not supported for directory buckets.

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The response returns the following HTTP headers.

ETag

Entity tag for the uploaded object.

General purpose buckets - To ensure that data is not corrupted traversing the network, for objects where the ETag is the MD5 digest of the object, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

Directory buckets - The ETag for the object in a directory bucket isn't the MD5 digest of the object.

x-amz-checksum-crc32

The base64-encoded, 32-bit CRC32 checksum of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

x-amz-checksum-crc32c

The base64-encoded, 32-bit CRC32C checksum of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

x-amz-checksum-sha1

The base64-encoded, 160-bit SHA-1 digest of the object. This will only be present if it was uploaded with the object. When you use the API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

x-amz-checksum-sha256

The base64-encoded, 256-bit SHA-256 digest of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

x-amz-expiration

If the expiration is configured for the object (see PutBucketLifecycleConfiguration) in the Amazon S3 User Guide, the response includes this header. It includes the expiry-date and rule-id key-value pairs that provide information about object expiration. The value of the rule-id is URL-encoded.

Note

This functionality is not supported for directory buckets.

x-amz-request-charged

If present, indicates that the requester was successfully charged for the request.

Note

This functionality is not supported for directory buckets.

Valid Values: requester

x-amz-server-side-encryption

Note

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

Valid Values: AES256 | aws:kms | aws:kms:dsse

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

If x-amz-server-side-encryption has a valid value of aws:kms or aws:kms:dsse, this header indicates the ID of the AWS Key Management Service (AWS KMS) symmetric encryption customer managed key that was used for the object.

Note

This functionality is not supported for directory buckets.

x-amz-server-side-encryption-bucket-key-enabled

Indicates whether the uploaded object uses an S3 Bucket Key for server-side encryption with AWS Key Management Service (AWS KMS) keys (SSE-KMS).

Note

This functionality is not supported for directory buckets.

x-amz-server-side-encryption-context

If present, indicates the AWS KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value is stored as object metadata and automatically gets passed on to AWS KMS for future GetObject or CopyObject operations on this object.

Note

This functionality is not supported for directory buckets.

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

If server-side encryption with a customer-provided encryption key was requested, the response will include this header to confirm the encryption algorithm that's used.

Note

This functionality is not supported for directory buckets.

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

If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide the round-trip message integrity verification of the customer-provided encryption key.

Note

This functionality is not supported for directory buckets.

x-amz-version-id

Version ID of the object.

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects. 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.

Note

This functionality is not supported for directory buckets.

Example 5 for general purpose buckets: Upload an object (Request server-side encryption using a customer-provided encryption key)

This example of an upload object requests server-side encryption and provides an encryption key.

PUT /example-object HTTP/1.1 Host: example-bucket.s3.<Region>.amazonaws.com Accept: */* Authorization:authorization string Date: Wed, 28 May 2014 19:31:11 +0000 x-amz-server-side-encryption-customer-key:g0lCfA3Dv40jZz5SQJ1ZukLRFqtI5WorC/8SEEXAMPLE x-amz-server-side-encryption-customer-key-MD5:ZjQrne1X/iTcskbY2example x-amz-server-side-encryption-customer-algorithm:AES256

Sample Response for general purpose buckets

In the response, Amazon S3 returns the encryption algorithm and MD5 of the encryption key that you specified when uploading the object. The ETag that is returned is not the MD5 of the object.

HTTP/1.1 200 OK x-amz-id-2: 7qoYGN7uMuFuYS6m7a4lszH6in+hccE+4DXPmDZ7C9KqucjnZC1gI5mshai6fbMG x-amz-request-id: 06437EDD40C407C7 Date: Wed, 28 May 2014 19:31:12 GMT x-amz-server-side-encryption-customer-algorithm: AES256 x-amz-server-side-encryption-customer-key-MD5: ZjQrne1X/iTcskbY2example ETag: "ae89237c20e759c5f479ece02c642f59"

Example 6 for general purpose buckets: Upload an object and specify tags

This example of an upload object request specifies the optional x-amz-tagging header to add tags to the object.

After the object is created, Amazon S3 stores the specified object tags in the tagging subresource that is associated with the object. For more information about tagging, see Object Tagging and Access Control Policies in the Amazon S3 User Guide.

PUT /example-object HTTP/1.1 Host: example-bucket.s3.<Region>.amazonaws.com Accept: */* Authorization:authorization string Date: Thu, 22 Sep 2016 21:58:13 GMT x-amz-tagging: tag1=value1&tag2=value2 [... bytes of object data]
