Just got the first end-to-end reply from a WhatsApp AI agent I'm building in n8n, and I'm way too happy not to share. What I'm building: a hotel booking assistant on WhatsApp. A guest messages, and the agent (Gemini + n8n) is meant to handle new bookings, lookups and reschedules using Google Sheets. Today the greeting reply came through, and the rest of the flows are still to be tested. Why it took 2 weeks (in case you're stuck too): - The trigger showed no executions at all, even though the webhook was verified. - Subscribing to the messages field wasn't enough. I also had to subscribe my WhatsApp Business Account to the app via the subscribed_apps call. - Meta allows only one webhook subscription per app, so n8n refused to run my new trigger until I deleted the old one. - Testing a trigger node on its own only runs that one node. Run the whole workflow (or pin the trigger data) to see the full flow. Next up: publishing it and testing the booking flows end to end. If you're building WhatsApp automations, what's been your biggest roadblock?
