Webhook Catch & Inspect

Generate temporary endpoints to catch, inspect, and debug incoming HTTP webhooks.

Privacy: Server-Assisted. This tool calls /api/* for CORS proxies or TLS inspection. Payloads are not retained.

Create a temporary catch URL, point a webhook at it, and inspect method, headers, and body in real time (SSE). In-memory — resets on server restart.

What is a webhook catcher?

When integrating Stripe, GitHub, Slack, or custom callbacks, you need a public URL that records inbound HTTP requests so you can verify signatures, headers, and payloads.

This tool issues a temporary endpoint and shows captured requests for short-lived debugging.

How to use this tool

  1. Create a temporary webhook endpoint and copy the URL into your provider or app.
  2. Trigger the webhook and open the captured request list.
  3. Inspect method, headers, and body, then discard the endpoint when you are done.

Frequently asked questions

How long are webhook payloads kept?

Endpoints and captures are temporary debugging aids and are not intended as long-term storage for production secrets.

Is my data sent to a server?

Webhook Catch & Inspect is hybrid: browser-first where possible, with short-lived server assistance (for example CORS proxies or TLS inspection) processed in memory and not retained as payload logs.
