Why did my webhook fail? Webhook failures usually come from one of these: - the endpoint was unreachable - the signing secret was wrong - the handler returned a non-2xx response - the handler took too long Fastest checks 1. confirm the signing secret 2. confirm the endpoint is public and reachable 3. inspect the exact response code 4. make sure heavy work happens after the request is acknowledged Read the fuller implementation guide at Webhooks and API Quickstart. If you need support, open the widget with the endpoint, status code, and approximate timestamp.
