GetObjectAcl

Returns the access control list (ACL) of an object

To use this operation, you must have s3:GetObjectAcl permissions or READ_ACP access to the object.

By default, GET returns ACL information about the current version of an object. To return ACL information about a different version, use the versionId subresource.

Note

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket.
