First working n8n WhatsApp AI receptionist for a dental clinic, with two snags
vxdant23 · reddit · 2026-09-25
A developer shares their first end-to-end working WhatsApp automation: a dental clinic AI receptionist built with n8n — WhatsApp Trigger → IF node to prevent loops → AI Agent (Gemini + Simple Memory) → tools (Google Sheets for clinic info, bookings, emergencies) → reply message.
They're stuck on two issues: whether the trigger is truly live since replies sometimes require clicking "Execute Workflow" on n8n Cloud, and why the AI verbally confirms bookings without any new row appearing in the Bookings sheet — likely a tool-calling reliability problem worth watching for anyone building agent workflows.
