Implement dynamic access expiry for Shared Drives

A delegated service account reviews and revokes Shared Drive membership on a schedule, enforcing time-based access for external or internal users.

Who it is forIT administrators managing time-limited access to Shared Drives for contractors, projects, or rotating teams.

The problem

Temporary collaboration often outlives its intended window, leaving Shared Drives accessible to users who no longer need them. Manual review is unreliable and doesn't scale, especially across dozens or hundreds of drives and group memberships.

How it works

  1. A delegated service account enumerates Shared Drives and their memberships on a regular schedule.
  2. It cross-references each member against an expiry policy, which may be set by group membership, custom attributes, or external records.
  3. For members whose access has expired, it calls the Drive API to remove them from the Shared Drive.
  4. It logs every removal, including the membership and drive identifiers, for audit and troubleshooting.
  5. Optionally, it notifies affected users or administrators of upcoming or completed revocations.

What changes

Access windows are enforced without manual effort, reducing risk from orphaned permissions and making audits straightforward.

The trap in this one. Drive API membership removals are eventually consistent. If you remove a user and immediately re-enumerate, the membership may still appear for several seconds — so a naive script can mistakenly treat removals as failures and retry, leading to spurious errors or excessive API calls. Batch jobs that process drives in rapid succession are especially prone to this, and error logs will reflect removals that actually succeeded.

Questions people ask

Can I set expiry natively in Google Drive?

Drive supports expiry for file and folder sharing with individuals, but not for Shared Drive memberships. Automating removals is the only way to enforce true membership expiry.

How do I avoid removing the wrong user?

Always track removals by both user email and role, and avoid wildcard deletions. Logging every action with identifiers is essential for later audit.
