Obtaining the Default WORM Policy of a Bucket

Functions

This operation returns the default WORM policy of a bucket.

To perform this operation, you must have the GetBucketObjectLockConfiguration permission. The bucket owner can perform this operation by default and can grant this permission to others by using a bucket policy or a user policy.

If you have never configured the default bucket-level retention policy after you enable WORM for a bucket, you can still use this API to check whether WORM is enabled.
