Webhook Tester

A webhook is an HTTP request that a server sends to a URL you specify when a particular event occurs. Unlike traditional APIs where your application polls for new data, webhooks push data to your endpoint the moment something happens — a payment is completed, a commit is pushed, or a form is submitted. This event-driven approach is more efficient and provides near real-time updates.

During development, testing webhooks can be tricky. You need to verify that your endpoint handles the correct HTTP method, parses the request body properly, validates authentication headers, and returns the right status code. This tool lets you craft a request with any method, headers, and body, then inspect the full response to diagnose issues quickly.

Common failure modes include timeouts when the receiving server takes too long to respond, sending the wrong Content-Type header (many endpoints expect application/json), CORS restrictions when testing from a browser, and missing or incorrect authentication tokens. Each of these problems produces different error signatures that this tool helps you identify.

In production, webhooks can fail silently. A server restart, a DNS change, or an expired certificate can cause deliveries to drop without anyone noticing. That is why monitoring matters. Once your endpoint is ready, schedule it to run on any cron schedule with Recuro — it handles execution, retries, alerting, and logging so you never miss a failure.
