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 1000 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. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.
Directory buckets - S3 Versioning isn't enabled and supported for directory buckets.
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.
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.
Directory buckets - MFA delete is not supported by directory buckets.
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 versioning-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
.
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.
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com
.

This example shows how to delete multiple objects in a single request.
Note that the call may not delete all objects. In that case, an exception
will be thrown. This exception will contain the list of encountered
delete errors.
