In this detailed video, I demonstrate how to build the most advanced AI appointment setter from the ground up using Vapi AI, Make.com, Airtable, Twilio, and Cal.com. This tutorial focuses on creating a transient agent capable of picking up calls, booking appointments, updating conversation logs, and providing an in-depth custom dashboard. You'll learn how to set up the Vapi environment, buy and import a Twilio number, create a successful make router scenario, and use advanced memory and tools for appointment setting. This guide also covers how to effectively handle call data in an Airtable interface and automate booking through the cal.com API, ensuring seamless appointment management.
