🎙️ *Video Description: Voice AI Appointment Booking with Vapi & n8n*

In this comprehensive tutorial, I'll guide you step-by-step through setting up a powerful, custom voice assistant that can handle customer interactions, manage CRM data, and schedule appointments—all hands-free!

We use *Vapi* to create the voice agent and its conversational logic, and *n8n* as the powerful, low-code automation backbone to handle all the backend tasks.

**What You Will Learn: **

*Vapi Assistant Setup: ** Configure a new Voice AI Assistant in the Vapi console, including setting up the model (GPT 4.1 Mini) and defining the **System Prompt* for the agent's identity and communication style.
*n8n Workflow Integration (MCP Server Trigger):* See how to create a master n8n workflow using an *MCP Server Trigger* to orchestrate multiple sub-workflows for different agent tasks (like "Call Client Lookup," "Call Book Event," "Call Update Appointment," etc.).
*Vapi Tool Linking: ** Learn how to define and link the n8n workflow as a **Tool* inside the Vapi Assistant using the MCP URL, allowing the AI to call your custom backend logic.
**Phone Number Setup: ** Configure a phone number in Vapi and attach it to your Voice Assistant for inbound calls.
**Live Demonstration: ** Watch a live call where the Voice Assistant performs a full customer flow:
**CRM Lookup: ** Checking for an existing client profile by asking for an email address.
**Data Update: ** Updating the CRM (Google Sheet) with the client's full name and phone number.
**Appointment Booking/Rescheduling: ** Checking the Google Calendar for availability and then booking/rescheduling an "Interior Detailing" appointment.
**Real-time CRM & Calendar Updates: ** See the n8n workflows execute in real-time, instantly updating a Google Sheet (acting as the CRM/Appointment Log) and the Google Calendar, followed by a confirmation email sent to the user.

This "Unicorn Build" demonstrates the power of combining Vapi's advanced voice capabilities with n8n's robust automation to create sophisticated, real-world AI applications.
