Buckets: update

Updates the metadata of a bucket. Changes to the bucket are readable immediately after writing, but configuration changes may take time to propagate.

Caution: You should generally use the PATCH method, which changes only metadata you define in the request. The UPDATE method might change certain metadata for the bucket even if that metadata is not specified in the request.

Required permissions

The authenticated user must have the storage.buckets.update IAM permission to use this method. To update public access prevention policies or access control lists (ACLs), the authenticated user must also have the storage.buckets.setIamPolicy permission. To return ACLs as part of the response, the authenticated user must also have the storage.buckets.getIamPolicy permission.

Request
