WATCH A WEBHOOK MOVE

From external event to your development server.

A webhook is an HTTP request sent automatically when something happens. Localmachine gives that request a public place to land, makes it readable, and lets you send it again.

  1. 01
    Capture

    Add your unique public URL to the webhook provider.

  2. 02
    Inspect

    See exactly what arrived, including JSON, headers and query parameters.

  3. 03
    Forward or replay

    Resend to your Localmachine tunnel or any custom HTTPS URL while debugging.

Online webhook testing

Test, inspect and replay webhooks from one inbox

Use a temporary public HTTPS endpoint to capture real webhook deliveries, inspect every request, and replay the original payload while you debug an integration.

Receive webhooks at a public URL

Create an inbox URL for GitHub, Stripe, Razorpay, Shopify or any service that sends HTTP callbacks.

Inspect headers and JSON payloads

Review the HTTP method, path, query string, content type, request headers and syntax-highlighted body in one view.

Replay the exact webhook request

Forward a captured delivery to your development endpoint without waiting for the provider to trigger the event again.

Debug safely with short retention

Sensitive headers are redacted, private network destinations are blocked and captured events expire automatically.

  1. Create an inbox and copy its URL.
  2. Send a webhook and inspect the delivery.
  3. Replay it to an HTTPS endpoint or Localmachine tunnel.

Webhook testing questions

What is a webhook testing tool?

A webhook testing tool gives you a public endpoint that records incoming HTTP requests so you can inspect and troubleshoot webhook integrations.

Can I replay a captured webhook?

Yes. Select a delivery and replay the same method, headers and body to an allowed HTTPS development endpoint.

Can I test webhooks on localhost?

Yes. Create a Localmachine tunnel for your local server, then choose that tunnel as the webhook replay destination.

Which webhook providers can I test?

You can receive standard HTTP webhooks from GitHub, Stripe, Razorpay, Shopify and other providers that accept a public HTTPS callback URL.

How long are webhook events stored?

Webhook deliveries use short automatic retention, and the current retention period is shown in the inbox.
