Bulk update Drive permissions via delegation

Apply or remove sharing permissions across large sets of files using a delegated service account, avoiding manual intervention.

The problem

Manually adjusting sharing on hundreds or thousands of files is slow and error-prone, especially after an organisational change or access review. Delegated automation can enforce new policies quickly, but must handle complex sharing states and edge cases.

How it works

  1. Impersonate each file owner or use the service account with domain-wide delegation.
  2. Enumerate target files and current permissions in batches.
  3. Apply permission changes (add, remove, or modify) using batched Drive API calls.
  4. Log all actions and re-check for any permissions that failed to update.
  5. Repeat for all affected users or shared drives.

What changes

Access changes are applied consistently and auditable, reducing risk of missed or inconsistent permissions.

The trap in this one. Drive API batch updates are not atomic: if one permission change in the batch fails (e.g. due to a transient backend error or a revoked user), the API returns a partial success without rolling back prior changes. This leaves files in a mixed state, and unless you re-read permissions after each batch and reconcile, your automation will report 'success' while actual sharing diverges from policy.

Questions people ask

Can I update permissions on files not owned by users in my domain?

No, delegated service accounts cannot modify permissions on externally owned files; those calls return 403 errors even if the file is shared into your domain.

How should I handle partial failures in bulk updates?

Always re-fetch permissions after each batch and retry failed changes. Log each result and reconcile at the end to catch silent mismatches.
