The problem

Manually updating permissions for Shared Drives is slow and error-prone when hundreds are involved. Scripts must handle inherited permissions, group memberships, and avoid partial updates that leave access inconsistent.

How it works

  1. Enumerate all Shared Drives via the Drive API with the delegated service account.
  2. For each drive, list current permissions and identify the required changes.
  3. Apply add, update, or remove actions using the permissions.create, permissions.update, and permissions.delete endpoints.
  4. Implement retry logic for 403 and 429 errors, and verify post-update permissions to confirm changes.

What changes

Drive access is updated consistently and quickly, with full auditability and no missed Shared Drives.

The trap in this one. Drive API permission changes on Shared Drives can silently succeed without propagating to all files, especially if files were previously moved in from other Drives or have custom permissions. Bulk updates must always include a pass to 'fix inheritance' (permissions.update with supportsAllDrives=true and transferOwnership=false) or some files will retain stale access, which is not visible from the drive-level permissions list.

Questions people ask

Why can't I just update the Shared Drive's permissions and be done?

Files with custom permissions (often due to move operations) retain their settings until explicitly reset. The Drive-level update does not override these.

What about API rate limits?

Bulk operations will hit 429 errors; you need exponential backoff and batching to avoid partial updates.

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
