Overview
The Webhook Tester is a tool that generates unique URLs to receive, capture, and inspect HTTP requests in real-time. It works like a "mailbox for HTTP requests" — you create an endpoint, get a URL, and any request sent to that URL is recorded and displayed instantly.
What are Webhooks?
Webhooks are HTTP callbacks — automated messages sent from one system to another when an event occurs. For example:
- Payment processors (Stripe, PayPal) send a webhook when a payment succeeds or fails.
- Git platforms (GitHub, GitLab) send a webhook when code is pushed.
- Monitoring services send a webhook when an alert is triggered.
- Mail servers send a webhook for inbound emails or delivery status.
Why Use the Webhook Tester?
During development and integration work, you often need to:
- Inspect the exact payload a third-party service sends you.
- Debug webhook integrations without deploying your application.
- Test different responses — simulate errors, delays, or custom status codes.
- Verify header and authentication data sent by webhook providers.
- Share webhook data with team members for collaborative debugging.
