Webhook Debugging

A webhook debugger built for real integration work

HookNexus helps you debug live webhook deliveries with request history, replay dispatch, full payload inspection, WebSocket updates, and CLI forwarding to localhost.

See every request

Capture headers, query parameters, raw bodies, timestamps, and request size in one dashboard instead of checking scattered provider logs.

Replay to live clients

Plus can dispatch saved requests to an online CLI or API key client so you can retest downstream handlers without retriggering the provider.

Forward to localhost

Use the HookNexus CLI to pipe captured traffic into your local app with a full URL target, no inbound tunnel setup in your framework.

When HookNexus fits best

  • You are integrating Stripe, GitHub, Shopify, Slack, or another webhook-heavy API and want request history without standing up a public callback.
  • You need to compare provider deliveries against what your app receives before or after code changes.
  • You want a lighter workflow than combining a request bin, tunnel, and custom debug logging.
  • You searched for a request inspector or webhook viewer, but you really need the full debugging path after the request is visible.

Before you change code

Check whether the provider actually sent the event, what headers arrived, and whether the body shape matches your handler expectations.

Before you blame retries

Look at repeated deliveries, request timing, and the captured body first. Many webhook bugs are payload or routing issues before they are retry issues.

Before you add more tools

If you are combining a request bin, a tunnel, and custom logs, a webhook debugger is usually the simpler place to start.

FAQ

Can I use HookNexus without forwarding to localhost?

Yes. Many teams start by capturing and inspecting requests in the dashboard, then add localhost forwarding only when they want to test local handler changes.

Is this only useful for Stripe or payment webhooks?

No. The same workflow works for GitHub, Shopify, Slack, and generic HTTP callbacks. The value comes from seeing the real request and deciding what to do next.

When does replay matter most?

Replay is most useful when the original event is expensive, slow, or inconvenient to trigger again. It gives you another pass with the same saved request.
