Webhook debugging: a production workflow
Webhook debugging is evidence correlation across the sender, network path, receiver, and downstream application. Checking only one log source usually leaves a gap.
The webhook failure path
| Stage | Question |
|---|---|
| Event creation | Did the provider create the expected event? |
| Delivery | Did it send to the intended URL, and what response did it receive? |
| Ingress | Did your infrastructure receive the same headers and body? |
| Authentication | Did signature or token verification pass? |
| Parsing and routing | Did the handler recognize the event type and schema? |
| Processing | Did queues, databases, and dependencies complete the intended action? |
Minimum evidence to collect
- Provider event or delivery ID.
- Destination URL, attempt time, response status, and response body.
- Request method, headers, query parameters, and raw body.
- Validation result and the exact failing stage.
- Application trace or log entries correlated to the same event.
- Retry and replay history.
Debugging procedure
- Start with one failed event rather than aggregate symptoms.
- Confirm the event was created and sent to the expected endpoint.
- Compare the sender record with the request captured at ingress.
- Resolve authentication and parsing before investigating business logic.
- Trace the event through queues and data stores using a stable correlation ID.
- Form one hypothesis, change one variable, and send a new event.
- Verify the user-visible or system-visible outcome, not only the HTTP response.
Avoid destructive debugging
When Hookmetry helps
Hookmetry provides the ingress-side request record, validation diagnostics, reconstruction steps, replay history, and controlled replay. Use it alongside the provider delivery record and application logs.
