What is Webhook Tester?

The Webhook Tester is a developer tool that provides you with a unique, temporary HTTP endpoint. Any payload sent to this URL (via POST, GET, PUT, etc.) will be caught and instantly displayed in your browser. It acts as an easy "catch-all" bucket for debugging APIs and third-party webhook integrations.

How to Use Webhook Tester

1. When the page loads, a unique Endpoint URL is automatically generated for you. 2. Click the "Copy URL" button to save it to your clipboard. 3. Paste this URL into the service you want to test (e.g., Stripe, GitHub, Shopify, or a custom script). 4. Trigger an event in that service. The incoming request (including Method, Headers, Query Parameters, and Body) will instantly appear in the logs below. 5. You can clear the logs or generate a fresh URL at any time.

Common Use Cases

  • Testing ecommerce payment gateways (Stripe, PayPal) to see exactly what payload they send when a purchase succeeds.
  • Debugging GitHub/GitLab repository webhooks on push or merge events.
  • Verifying that your own backend code is sending outbound HTTP requests with the correct headers and formatted JSON body.
  • Acting as a temporary mock endpoint during frontend development.

Frequently Asked Questions

Are my webhook payloads saved permanently?

No. This is a temporary, in-memory demo tool. All received requests are stored strictly in server memory and are automatically wiped if the server restarts or if you close the session. Never send sensitive data (like real passwords or production API keys) to this tool.

Which HTTP methods are supported?

The endpoint accepts all standard HTTP methods: GET, POST, PUT, PATCH, DELETE, OPTIONS, and HEAD.

What content types does it parse?

It will automatically attempt to parse JSON (`application/json`) and Form Data (`application/x-www-form-urlencoded`). For any other content type, it will display the raw text body.

Is there a limit on the number of requests?

To prevent abuse, each unique endpoint ID will only cache the 50 most recent requests.
