A webhook integration is only as trustworthy as what actually gets sent and received, and neither side of that exchange is visible without a real endpoint to point the request at and a way to inspect what came back, the payload, the headers, the exact response time, rather than assuming it worked because nothing crashed. This tool provides a live endpoint that accepts a webhook payload and shows the full response along with its timing, letting an integration be tested against something real rather than guessed at. Useful for verifying what payload a payment provider or a CI system actually sends before writing code to handle it, confirming a server's webhook response looks correct before going live, or diagnosing a slow webhook by seeing its actual response timing.
