Webhook Tester & Payload Simulator

Simulate webhook events from Stripe, GitHub and PayPal and inspect their payloads and headers in your browser. Useful for learning event shapes and drafting handler code — it does not receive live requests from real services.

Test Webhook Endpoint Without Server

Start a simulation session, then generate sample Stripe, GitHub or PayPal events to inspect. Sample URLs do not receive live requests.

Frequently Asked Questions

Everything you need to know about testing webhooks online

It is a webhook payload simulator that runs in your browser. Click a provider button (Stripe, GitHub or PayPal) and the tool creates a realistic sample event with headers, body and timestamp so you can study its structure, copy it into your own tests, and practise custom response codes. It does not host a live endpoint, so real services cannot send requests to it.

Yes, our webhook tester tool is completely free. You can generate unlimited sample events and inspect their payloads without any registration or payment. It's designed to help developers test webhooks quickly and efficiently.

No. The sample URL uses the reserved webhook.example domain and exists only as a placeholder in the simulated requests. To capture live traffic, point the service at an endpoint you run (for example a local server exposed with a tunnelling tool) or a dedicated request-capture service.

You can simulate typical Stripe payment_intent.succeeded, GitHub push and PayPal PAYMENT.CAPTURE.COMPLETED events and inspect their JSON and headers. The payloads are realistic samples, not signed events from those services, so signature checks in your code will not pass against them.

The simulated events are JSON POST requests with provider-style headers (Content-Type, User-Agent and, for Stripe, a sample Stripe-Signature header). You can also set a custom response body, status code and delay to see how your handler logic might react.

Yes. Everything is generated in your browser and nothing is sent to our servers. Refreshing the page clears the simulated requests.

Not for capturing live requests: webhook.site gives you a real public endpoint, while this tool only simulates payloads. Use it to learn event shapes and draft handler code; use a live capture service or your own endpoint for end-to-end tests.

Use our webhook tester to verify that your service is sending requests correctly. Check the request method, headers (especially authentication), payload format, and timing. The detailed inspection view helps identify common integration issues.

While this tool is designed to receive webhooks, you can use tools like curl, Postman, or any HTTP client to send test requests to your generated webhook URL and see how they appear in the interface.

Yes, our webhook tester is fully responsive and works perfectly on mobile devices, tablets, and desktops. You can generate URLs, receive webhooks, and inspect requests from any device with a web browser.
