The problem

Manual permission updates on shared Drives and folders lag behind reality, leaving ex-members with access and new members blocked. Over time, this creates real data exposure and support noise.

How it works

  1. Maintain a source of truth for project roles (e.g., a spreadsheet or directory group).
  2. Fetch the current Drive permissions for the project folder using the Drive API.
  3. Compare assigned permissions to the source of truth to identify who needs to be added or removed.
  4. Automate permission changes: remove ex-members and add new members using the Drive API.
  5. Log every change and alert on failures.

What changes

Drive access matches current project membership, and onboarding or offboarding is reflected within minutes, not weeks.

The trap in this one. Drive API permission removals are eventually consistent. A user removed from a folder can still access it for up to several minutes, and re-adding before propagation completes can yield 'already has permission' errors or, in rare cases, leave the user with duplicate roles. Never assume immediate effect or rely on a single atomic revoke-add cycle per user.

Questions people ask

How do I handle nested folders in shared drives?

Inherited permissions make nested structures tricky. Always check and update permissions at the shared drive or root folder level, not per subfolder, unless you have a strong reason.

Can I batch permission changes?

You can, but the Drive API may throttle large batches. Stagger changes and watch for 403/quota errors to avoid partial updates.
