How to Review Cybersecurity Before Connecting a Vendor to Internal APIs

A vendor integration can receive broad API access to internal systems even when it only needs a small set of records. Vendor credentials and permissions may persist after the project ends.

What to check

Identify the data requested, API scopes, authentication method, secret storage, vendor staff access, logging, retention, incident notice terms, and offboarding process. Confirm whether access can be limited to a test tenant or specific endpoints.

Recommended next step

Use a named integration identity with the minimum required scopes, an owner, and a review or expiry date. Monitor use and revoke credentials promptly when the integration is no longer needed.
