# n8n production webhook returns 200 but creates no execution

An HTTP response proves only that some HTTP layer answered. It does not prove
that n8n created an execution, a worker ran the workflow, or the intended
business outcome occurred.

The checker:

- requires an exact confirmation that no irreversible side effect can occur;
- sends a minimal synthetic GET or POST with one correlation ID;
- accepts no credential, token, cookie, query string, fragment, or customer
  payload;
- refuses cleartext remote HTTP and `/webhook-test/`;
- does not follow redirects; and
- omits the target URL and response body from its report.

Use a cloned or sandbox workflow, or disable every irreversible downstream side
effect before running:

```bash
bash n8n-webhook-ingress-check.sh \
  --confirm-no-irreversible-side-effects \
  https://n8n.example.com/webhook/your-safe-probe \
  POST
```

## Three diagnostic branches

1. **HTTP response, no n8n execution:** verify the exact production path and
   method, published or active state, webhook registration, receiving
   hostname, proxy rewrite, and queue-mode routing.
2. **Execution exists and fails:** inspect the first failed node, response
   mode, payload size, binary handling, worker availability, timeout, memory,
   and first divergent input shape.
3. **Execution succeeds but the outcome is missing:** trace the external state
   with the same idempotency key. A green run is not proof that a CRM record,
   message, file, booking, or payment changed.

If an imported or deployed workflow fires only after a re-save, preserve its
workflow ID, saved revision, published state, deployment timestamp, and startup
registration log before changing it. In n8n environments, source control moves
the saved workflow; the receiving production instance still requires a
separate publish step.
