Why this tool is safe

This page does not send HTTP requests to user-provided URLs. It only creates sample JSON and curl commands, which avoids turning the service into an open webhook sender.

Webhook testing checklist

Accept JSON with the expected content type.
Log event IDs for idempotency checks.
Return a fast 2xx response after validation.
Retry safely when downstream systems fail.
Never log verification codes or secrets unnecessarily.
