Synchronise Google group memberships with your HR system

Keep mailing lists and permissions accurate by regularly syncing group memberships from your HR source of truth via a delegated service account.

The problem

Manual group management is error-prone and always lags behind reality. When people move teams or leave, permissions linger, and audits find inconsistent access.

How it works

  1. Export current group membership state from the HR system.
  2. Fetch existing group memberships from the Directory API using a delegated service account.
  3. Calculate the required additions and removals to match the HR state.
  4. Apply changes via the Directory API, handling paging and batching for large groups.
  5. Log every change and alert on failures or unexpected deltas.

What changes

Group memberships directly reflect HR records, reducing manual effort and audit exceptions.

The trap in this one. The Directory API applies changes asynchronously: removals may not be visible immediately, and re-adding a user too quickly after removal can silently fail or result in transient inconsistencies. Scripts that do not account for propagation delay between operations—especially in loops—produce mismatched group states and confusing audit logs.

Questions people ask

How often should the sync run?

Synchronising once or twice daily is common, but frequency should match how often group-critical HR changes occur. Avoid running too frequently to reduce the risk of hitting propagation issues.

What if the HR system and Google group disagree?

The HR system should be treated as authoritative. Always reconcile by making Google match HR, and alert if unexpected discrepancies persist after sync.
