Ready to build a complete AI Receptionist? In this tutorial, we use Vapi and n8n to create an advanced, human-like voice AI that can schedule, reschedule, and delete appointments directly with your calendar and database.

✅ Full Appointment Management: Build the Vapi function calls and n8n workflows to schedule, reschedule (update), and delete appointments.
✅ Advanced Knowledge Base: Learn how to add a custom knowledge base to your Vapi assistant using external files (like PDFs or text) so it can answer specific questions about your business.
✅ Prompt Engineering: We'll write a robust system prompt with a defined personality (persona) and critical safety rules to set boundaries for the AI.
✅ Error Handling in n8n: See how to build reliable workflows that can handle errors gracefully as the AI talks to your APIs.
✅ Live Demo: Watch the AI receptionist handle a real call, schedule a meeting, and then reschedule it.
