Send HTTP requests to any endpoint from your browser. Test webhooks, debug APIs, inspect responses.
A webhook is an HTTP callback — when an event happens in one system, it sends an HTTP request to a URL you specify. Stripe sends payment events, GitHub sends push notifications, Slack sends message events. Your server receives these and acts on them.
Enter your webhook URL, choose the HTTP method, add headers and a request body, then hit Send. The response status, headers, and body are displayed below. Everything runs from your browser — we don't proxy or store your requests.
Webhooks need a publicly accessible URL. If you're building locally, you need a server to receive them.
