Webhook Not Firing? A Cross-Platform Guide to Debugging Bot Webhooks

A debugging guide explains that 'my webhook is not firing' can stem from three separate failures: the platform never sending the request, the request being rejected by the receiving server, or the server accepting it without any downstream effect. It recommends first identifying which side is at fault, using a table that maps each symptom to its likely location and first check. The guide advises logging the raw incoming request before any framework middleware processes it, since this often exposes the problem immediately. A top-to-bottom checklist follows, starting with testing the URL from outside the network and interpreting common status codes such as 404, 405, 301/308, and 403. The steps are verified against the documentation of Meta, Telegram, Slack, Discord, and Stripe as of August 2026.
