How to use

  1. Generate an endpoint

    Click 'Generate endpoint' to get a unique URL. Copy it to your clipboard.

  2. Send requests to the URL

    Configure your webhook source (Stripe, GitHub, Zapier, etc.) to send to the generated URL. Or test with curl.

  3. Inspect requests

    Incoming requests appear in the log in real time. Click any request to expand and see method, headers, and body (JSON pretty-printed).

  4. Clear or regenerate

    Click 'Clear log' to reset the log, or 'New endpoint' to generate a fresh URL.

Common use cases

  • Testing Stripe or GitHub webhooks — Generate a temporary endpoint to receive and inspect webhook payloads from payment providers or CI systems during integration.
  • Debugging webhook payload structure — Inspect real webhook requests to understand the exact headers and body format before writing webhook handler code.
  • Verifying webhook delivery — Confirm that a third-party service is successfully delivering webhooks to your endpoint during integration testing.

Examples

  • Test a Stripe webhook

    Set the webhook URL in your Stripe dashboard to the generated endpoint and trigger a payment event

    Output
    POST request with Stripe-Signature header and JSON body showing the event payload

Frequently asked questions

How long does the endpoint last?
Endpoints expire after 60 minutes. After expiry, requests to the URL will not be logged. Generate a new endpoint when needed.
Is data stored after the endpoint expires?
No. Request data is stored in server memory only and is cleared when the endpoint expires or when you click 'Clear log'. Nothing is written to disk or a database.
How many requests can I receive?
Each endpoint stores the last 20 requests. Older requests are automatically dropped when the limit is reached.

Key concepts

Webhook
An HTTP callback that sends data to a URL when an event occurs — used by services like Stripe, GitHub, and Slack to notify systems of changes.
Payload
The data body of a webhook request, typically JSON, describing the event that triggered it.
Endpoint
A URL that receives HTTP requests — in webhook testing, a temporary endpoint captures incoming requests for inspection.
