Updated 2026-02-186 min read
Confirm API key scope
Ensure your key belongs to the intended organization and has not been revoked. Incorrect or stale keys are the most frequent auth issue.
Check auth header format
Use the exact Authorization header format expected by the API. Small formatting mistakes can trigger 401 responses.
Investigate environment mismatches
Verify you are calling the correct API base URL for your environment and that deployment variables are updated after key rotation.
