Synchronise Google Group memberships from your HR system

Drive Group membership from the HR source of truth, ensuring leavers and joiners are reflected in Workspace access within minutes.

The problem

Group memberships drift from HR status, so leavers retain access and joiners are blocked from resources. Manual updates are slow and error-prone, especially at scale or across multiple groups.

How it works

  1. Pull the current user-to-group mappings from the HR system.
  2. Fetch the authoritative Group membership lists via the Admin SDK.
  3. Calculate the diff: who needs to be added or removed from each Group.
  4. Apply the changes using the service account, impersonating an admin.
  5. Log all actions and surface errors for review.

What changes

Workspace Groups always mirror HR reality; access is granted and revoked on time, with an audit trail.

The trap in this one. Removing a user from a Group who is already pending removal (e.g. due to a prior API call or admin action) returns HTTP 200 with no change, but does not guarantee the user is actually out—membership can persist for minutes due to backend propagation. Blindly assuming a successful response means access is revoked leads to gaps, especially if you re-sync faster than Google’s eventual consistency window.

Questions people ask

How often should the sync run?

Every 10–30 minutes is typical, but avoid running more often than that—Google’s backend may not reflect recent changes instantly, and repeated removals can mask real errors.

Can we add or remove users in bulk?

The Admin SDK only supports single-member changes per request. Parallelise with care to avoid hitting rate limits.

Want this built?

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.
