What webhook testing is for
Webhooks are server-to-server messages triggered by events. A payment event, form submission, deployment, or automation can send a request to your endpoint. A webhook inbox helps you inspect what was actually sent before you wire it into production logic.
What to inspect
- HTTP method and request path.
- Headers used for signatures, content type, and sender identification.
- Raw body and parsed body.
- Timestamp and retry behavior.
- Whether the sender expects a specific response code.
Common mistakes
Do not test with live secrets unless the inbox is protected and you understand retention. Also remember that many webhook providers retry failed deliveries, so your endpoint should be idempotent.
FAQ
Should webhook payloads be stored forever?
No. Keep retention short unless there is a clear operational reason.
What is the first thing to check?
Confirm the sender, signature header, content type, and response code.
