Review third-party app access across all users
Enumerate OAuth grants to external apps for every user, so you can spot risky or unwanted integrations before they cause trouble.
| Who it is for | Security and compliance teams responsible for Workspace tenant integrity. |
|---|---|
| APIs | Admin SDK |
| Typical scopes | admin.directory.user.security, admin.directory.user.readonly |
The problem
Users authorise third-party apps without oversight, risking data exposure or compliance breaches. Manual checks are incomplete and quickly outdated, especially at scale.
How it works
- List all users in the domain with the Admin SDK.
- For each user, impersonate them and retrieve their authorised third-party OAuth clients via the security API.
- Aggregate and classify the discovered apps by risk or business need.
- Report findings to IT, flagging unknown or high-risk integrations.
What changes
Admins gain a timely view of every app with access to Workspace data, enabling prompt investigation or revocation.

Questions people ask
Can I revoke app access automatically?
You can, but bulk revocation via API is not supported for all app types. Review findings with stakeholders first to avoid disrupting business processes.
How fresh is the data returned?
There may be a delay of several hours between a user granting access and the API reflecting the new authorisation, especially for accounts that are infrequently used.
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.
