Audit and report on third-party Workspace access

Track which third-party apps hold access to Workspace data and report on risky or unused authorisations.

The problem

Third-party OAuth apps accumulate over time, often left with unused or excessive access. Manual checks miss changes, and without reporting, nobody knows which apps are still in use or if access has grown riskier.

How it works

  1. Use a delegated service account to call the Admin SDK Reports API.
  2. Fetch OAuth token and authorisation events for all users.
  3. Aggregate app authorisation data and flag apps with broad or unused permissions.
  4. Generate and distribute periodic audit reports to stakeholders.

What changes

Admins receive regular, actionable reports on which third-party apps hold access and which authorisations can be revoked.

The trap in this one. The Reports API only logs app authorisations and revocations from the point audit logging was enabled; historic access before that is invisible. If audit logging is toggled off and on, the gap is permanent and undetectable in the export. Always check the audit log coverage window before relying on the completeness of your report.

Questions people ask

How recent is the audit data?

The Reports API returns events from when audit logging was first enabled; it does not backfill prior activity. Always verify the earliest available event date.

Can this catch apps authorised via SAML or other non-OAuth methods?

No, the audit covers OAuth-based authorisations; SAML and other federated access must be audited separately.
