Troubleshooting

Common errors and how to resolve them.

401 Unauthorized

The API-Key is missing, wrong, or doesn't match the environment you're targeting. Check the authentication header and that the key belongs to the right environment.

403 Forbidden on an action

A policy denied the call, or default-deny on writes blocked a write with no allowing policy. Use the dry-run check to see which policy applies:

POST /api/v1/actions/{provider}/{action_name}/policy-check

A 403 on an approval means separation of duties blocked a self-approval.

202 Accepted instead of a result

The action needs approval. It's held with an approval_id until a different person approves it; it hasn't run yet.

404 on a connection

Either the connection doesn't exist, or it belongs to a different environment — cross-environment lookups return 404 by design. Confirm provider_config_key and connection_id, and that you're using the matching key.

Connection status is expired or error

The stored credentials are no longer valid. Re-run the connect flow or update the credentials. Use the /test endpoint to check health.

429 Too Many Requests

You've hit a monthly quota. Honor the Retry-After header; check the X-RateLimit-* headers for remaining headroom.

A webhook isn't arriving

Verify the subscription matches the event type and provider, that the inbound signature verifies, and inspect the event's status (it may be in dead_letter after failed forwarding).
