DeleteObject - Amazon Simple Storage Service

DeleteObject

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects.

To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource 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. To see sample requests that use versioning, see Sample Request.

You can delete objects by explicitly calling the DELETE Object API or configure its lifecycle (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.

The following operation is related to DeleteObject:

Request Syntax

DELETE /Key+?versionId=VersionId HTTP/1.1 Host: Bucket.s3.amazonaws.com x-amz-mfa: MFA x-amz-request-payer: RequestPayer x-amz-bypass-governance-retention: BypassGovernanceRetention x-amz-expected-bucket-owner: ExpectedBucketOwner

URI Request Parameters

The request uses the following URI parameters.

Bucket

The bucket name of the bucket containing the object.

When using this API with an access point, 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 operation using 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 Simple Storage Service Developer Guide.

Required: Yes

Key

Key name of the object to delete.

Length Constraints: Minimum length of 1.

Required: Yes

versionId

VersionId used to reference a specific version of the object.

x-amz-bypass-governance-retention

Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation.

x-amz-expected-bucket-owner

The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

x-amz-mfa

The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.

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. For information about downloading objects from requester pays buckets, see Downloading Objects in Requestor Pays Buckets in the Amazon S3 Developer Guide.

Valid Values: requester
