S3 / Client / delete_object

delete_object#

S3.Client.delete_object(**kwargs)#

Removes an object from a bucket. The behavior depends on the bucket’s versioning state. For more information, see Best practices to consider before deleting an object.

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 and to see example requests, see Using MFA delete and Sample request in the Amazon S3 User Guide.

Note

  • 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.

  • 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.

  • MFA delete is not supported by directory buckets.

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.

    Note

    You can also use PutBucketLifecycle to delete objects in Amazon S3.

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

    • 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 permissions.

  • Directory buckets 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.

    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:

See also: AWS API Documentation

Request Syntax

response = client.delete_object(
    Bucket='string',
    Key='string',
    MFA='string',
    VersionId='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string'
)
Parameters:

  • Bucket (string) –

    [REQUIRED]

    The bucket name of the bucket containing the object.

    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 Amazon Web Services 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 Amazon Web Services 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.

  • Key (string) –

    [REQUIRED]

    Key name of the object to delete.

  • MFA (string) –

    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.

    Note

    This functionality is not supported for directory buckets.

  • VersionId (string) –

    Version ID used to reference a specific version of the object.

    Note

    For directory buckets in this API operation, only the null value of the version ID is supported.

  • RequestPayer (string) –

    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.

  • BypassGovernanceRetention (boolean) –

    Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation. To use this header, you must have the s3:BypassGovernanceRetention permission.

    Note

    This functionality is not supported for directory buckets.

  • ExpectedBucketOwner (string) – 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).

Return type:

dict

Returns:

Response Syntax

{
    'DeleteMarker': True|False,
    'VersionId': 'string',
    'RequestCharged': 'requester'
}

Response Structure

  • (dict) –

    • DeleteMarker (boolean) –

      Indicates whether the specified object version that was permanently deleted was (true) or was not (false) a delete marker before deletion. In a simple DELETE, this header indicates whether (true) or not (false) the current version of the object is a delete marker.

      Note

      This functionality is not supported for directory buckets.

    • VersionId (string) –

      Returns the version ID of the delete marker created as a result of the DELETE operation.

      Note

      This functionality is not supported for directory buckets.

    • RequestCharged (string) –

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

      Note

      This functionality is not supported for directory buckets.

Examples

The following example deletes an object from an S3 bucket.

response = client.delete_object(
    Bucket='examplebucket',
    Key='objectkey.jpg',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}

The following example deletes an object from a non-versioned bucket.

response = client.delete_object(
    Bucket='ExampleBucket',
    Key='HappyFace.jpg',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
