Facebook Messenger Automation Bot built with n8n + AI

I’ve recently built a Facebook Messenger automation workflow that helps service-based businesses handle customer conversations automatically — from answering queries to booking appointments and sending confirmation emails.

🔧 What this automation does:

💬 Instantly responds to customer queries about services via Messenger
📅 Books appointments automatically with real-time availability checks
📧 Sends confirmation emails to customers after successful booking
🧠 AI-powered agent understands user intent and routes actions accordingly
🔄 Webhook-based architecture for fast and reliable message handling

Behind the scenes, the workflow uses:

An AI Agent connected with tools (calendar, email, data lookup)

Conditional logic to decide when to respond or take action

External API calls for dynamic operations

Memory and embeddings to provide better, context-aware responses

🎯 Who this is for:

✔️ Clinics & healthcare providers
✔️ Consultants & coaches
✔️ Salons & local service businesses
✔️ Any appointment-based or inquiry-driven business

🔧 Fully customizable
The workflow can be tailored based on a client’s business logic — services offered, booking rules, response tone, notification channels, or CRM integration.

This kind of automation helps businesses:
✅ Respond faster
✅ Reduce manual work
✅ Avoid missed inquiries
✅ Improve overall customer experience
