Delete an Object ACL

Last updated February 10, 2026

What this operation supports in Google Cloud Storage

Removes a specific ACL entry from an individual object, revoking that grantee's object-level permission.

After removal, the object falls back to whatever the bucket's default object ACL (or IAM policy, if using uniform access) otherwise grants.

This only applies to buckets using fine-grained access control rather than uniform bucket-level access.
