Automate Workspace group membership from external data

Synchronise Google Group memberships with an external source, updating group lists dynamically via delegated service account.

The problem

Access groups drift from the external source over time, causing users to retain or lack permissions they shouldn't. Manual updates are error-prone and slow, especially in large or multi-source environments.

How it works

  1. Extract the desired group memberships from your external source.
  2. Fetch the current group members using the Admin SDK as a delegated service account.
  3. Compute the add/remove delta for each group.
  4. Call Admin SDK to add or remove members as needed.
  5. Log and reconcile any errors or discrepancies after each batch.

What changes

Workspace group membership reflects the authoritative external system, reducing access creep and manual intervention.

The trap in this one. The Admin SDK's group membership changes can take several minutes to propagate, but the API responds immediately as if the change succeeded. If you re-read membership to validate or sequence changes in the same run, you will see stale data and may re-issue conflicting or duplicate operations. Always batch and checkpoint changes, and allow for propagation delay before verification or subsequent dependent actions.

Questions people ask

How many members can I add or remove in one batch?

The Admin SDK enforces API quotas and rate limits. For large groups, expect to handle 429 errors and implement exponential backoff.

Does this approach handle nested groups?

No, the Admin SDK only manages direct memberships. If your model relies on nested groups, you must reconcile them separately.
