AI Voice Receptionist Backend for Vapi - Book, Reschedule & Cancel Appointments (n8n Workflow)

Give your voice AI real power. This is the backend that lets a Vapi voice assistant manage appointments on its own.

WHAT THE VOICE AI CAN DO

- Check free time slots from your Google Calendar

- Book appointments and email a confirmation with an ID

- Reschedule and cancel by appointment ID, phone or email

- Look up and save patient/client details in Google Sheets

You control opening hours, days, slot length and time zone from one settings node. Double-booking is prevented by checking the calendar.

WHAT YOU GET

- Ready-to-import n8n workflow (.json)

- PDF guide including the 6 Vapi tool definitions and a starter voice prompt

- Google Sheet templates (Patients, Appointments)

- Credentials removed - you connect your own

YOU NEED

n8n, a Vapi account and a Google account (Calendar, Sheets, Gmail).

PERFECT FOR

Clinics, salons, dental offices, consultants, law firms and any appointment-based business - or agencies building voice AI for clients.

Note: this is the backend; you create the voice assistant in Vapi following the guide. Setup about 60-90 minutes. Need the ready-made Google Sheet or help? Message on WhatsApp 08083696435 or email [email protected]. Digital product: no refunds after download.
