Major highlight — Stuck on Webhooks + HTTP Requests (WhatsApp AI Automation)

OP is troubleshooting a WhatsApp AI automation where webhooks and subsequent HTTP requests are failing. Community responses focus on debugging the integration layer rather than the AI itself.

Top recommended debugging steps

  • Confirm the webhook receives the exact WhatsApp payload (no transformations).
  • Log the outbound request body right before the HTTP node so you see what n8n is sending.
  • Replay the exact request in Postman or curl until the external endpoint accepts it.
  • Consider a cleaner pattern: use a chat-data layer to handle webhook + reply logic, and let n8n run behind it for workflow logic.

If you want a cleaner pattern, chat data handles the webhook plus reply layer pretty well and lets n8n sit behind it for the actual workflow logic." 1 upvote

Quick updates

  • Checklist: Validate incoming webhook payload → Inspect n8n node input/output → Reproduce request externally.
  • If you're using unofficial WhatsApp libraries (baileys, wasender, etc.), expect different payload shapes and delivery behaviors than the official Business API.
  • Tip: Add a "Set" or "Function" node to stringify and log the outgoing body for easy copy/paste into Postman.
  • Want help? Paste a sanitized sample payload and the HTTP node body and someone will likely point out the mismatch.
