FAQ
- Is this just a JSON diff tool?
- No. APIDiffGuard monitors live endpoints, stores versioned baselines, schedules checks, and alerts on schema drift — the diff viewer is the signature surface, not the whole product.
- Can I ignore volatile fields?
- Yes. Ignore timestamps, UUIDs, request IDs, etags, and any custom JSON path per endpoint.
- Does the CLI use the same engine?
- Yes. apidiff check runs the same comparison logic and can fail CI on breaking severity.
- What auth types are supported?
- Bearer, API key, Basic, OAuth token, and custom headers.
