Synchronise Google Groups membership from external sources

Keep Google Groups in sync with your HR or directory system by reconciling group membership via the Admin SDK.

The problem

Manual group updates drift out of sync with the real organisation, causing access gaps or lingering privileges. HR and directory systems are the real source of truth, but Workspace groups drift unless actively reconciled.

How it works

  1. Fetch the current group membership from the external directory or HR system.
  2. List current members of each Google Group via the Admin SDK.
  3. Calculate additions and removals needed to match the source.
  4. Apply changes using batch member insert and delete calls.
  5. Log the membership diff for audit and troubleshooting.

What changes

Group membership reliably matches the external source, reducing manual errors and access creep.

The trap in this one. The Admin SDK's group member deletion is eventually consistent. Removing and re-adding a user in rapid succession can silently fail or leave the user missing, as the API may return success before the backend state updates. Always allow for propagation delay, and never assume immediate consistency when reconciling memberships in a tight loop.

Questions people ask

How often should the sync run?

Hourly or daily is typical. More frequent runs risk hitting rate limits or clashing with propagation delays.

What happens if a user is already in the group?

Adding an existing member is idempotent and safe, but removing and immediately re-adding in the same batch can trip eventual consistency issues.

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.
