Indie Dev Gets WhatsApp AI Dental Clinic Receptionist Working End-to-End in n8n

An indie developer got their n8n-built WhatsApp AI receptionist for a dental clinic fully working, sharing key fixes: a Meta/n8n webhook verification mismatch, and — crucially — pulling Google Sheets out of the AI agent's tool list entirely, having the agent output structured JSON (bookingready, isemergency, unanswered flags) with downstream IF nodes deciding sheet writes before any reply is sent, which killed the "AI lying about doing something" problem.
Flow: WhatsApp Trigger → IF (filter status loops) → AI Agent (Groq + Structured Output Parser + clinic info/services/datetime tools) → IF booking → IF emergency → append to matching sheet → send message.
They're now asking the community about stress-testing before client demos and going live with a real business number.
