Every webhook integration starts the same way: you paste a URL into a provider's dashboard and hope your endpoint handles whatever they send. The problem is that most of the debugging you need to do — checking headers, confirming the signature format, seeing what a retry looks like — has nothing to do with your endpoint code yet. You just need to see the request.
Pointing the provider straight at a local dev server means either tunneling traffic in (a separate tool, another thing that can go stale) or deploying half-finished handler code just to find out what shape the payload is. Neither is really about testing your integration logic.
A temporary inspection URL solves the first half of that problem on its own: give the provider a URL that just shows you every request as it lands — method, headers, body, timing — and you can confirm the provider's behavior before your handler exists at all. Once you know the shape of what's coming, writing the actual handler is the easy part.
That's what the Webhook here is for: a temporary URL, live delivery inspection, and a session that expires automatically so nothing lingers after the integration is done. Nothing about it requires an account, and secrets like Authorization headers get redacted on arrival.
