AI Appointment Scheduler (n8n + Twilio + Cal.com + Airtable)

This workflow builds an AI agent that handles appointment scheduling via SMS. It receives customer enquiries, checks availability, and confirms bookings. If no booking is made, it sends personalized follow-ups. Once booked, it can reschedule or cancel appointments without human input. The system uses Twilio for messaging and Airtable to track leads, with daily triggers to re-engage prospects and manage communication history.
