How long does a session last?

A session and its captured requests expire 24 hours after creation, and the last 100 requests are kept per session.

Is the URL guessable by someone else?

Session IDs are generated with a cryptographically random UUID, not a sequential counter, so they aren't practically guessable. Even so, treat the URL like any endpoint that might receive real data: don't route anything sensitive through it.

Webhook Echo & Logger

Generate unique webhook URLs to capture and inspect HTTP requests in real-time. Perfect for debugging webhooks and testing API integrations.

Generate a unique webhook URL to start capturing HTTP requests. Your webhook URL will be active for 24 hours and can receive unlimited requests.

About this tool

Generates a unique, temporary URL you can point any HTTP integration at, then shows the requests as they arrive: method, headers, and body, logged in near real time.

When you’d use it

Inspecting exactly what payload a third-party webhook (a payment provider, a CRM, a CI system) actually sends, before you write a handler for it.
Debugging why an integration you're building isn't receiving what you expect.
