Our take on the AI Voice Receptionist with Vapi, Google Calendar & Twilio SMS

This is an n8n workflow template that connects a Vapi AI voice assistant to Google Calendar, Twilio SMS and Google Sheets so phone calls can book, reschedule and cancel appointments without a human. A webhook receives Vapi tool-call requests during a call, checks open slots against clinic hours and slot length, then writes the event and texts the caller a confirmation. It also looks up upcoming appointments by phone number and logs message-taking requests to a sheet. It suits clinics, salons and small service businesses already using Vapi and n8n; it is not a hosted product, so you supply the accounts, credentials and telephony.

About the AI Voice Receptionist with Vapi, Google Calendar & Twilio SMS

This is an n8n workflow that lets a Vapi AI voice assistant handle appointment calls. During a call, it receives Vapi tool-call requests through a webhook, normalizes the caller's phone number, and routes each request by tool name.

It checks availability by reading the selected day's Google Calendar events and returning open time slots based on clinic hours and slot length. It books appointments by creating a Google Calendar event and sending the caller a Twilio SMS confirmation. It can also look up a caller's upcoming events by phone number and return a formatted list that includes event IDs. To reschedule or cancel, it updates or deletes the event and texts the caller the update.

Message-taking and unknown requests are appended to Google Sheets, or return an error message. When Vapi sends its end-of-call report, the workflow detects missed calls and sends an SMS follow-up. Inbound Twilio SMS replies are answered with a fixed TwiML message through a webhook.

Questions and answers

Do I need a Vapi account to use this?
Yes. The workflow is built around Vapi tool-call requests arriving at a webhook, so you need a Vapi assistant configured with matching tools. n8n, Google Calendar and Twilio accounts are also required.
How does it decide which slots are open?
It reads the selected day's Google Calendar events and returns open slots based on the clinic hours and slot length set in the workflow. You edit those values to match your schedule.
Can callers reschedule or cancel by phone?
Yes. The workflow updates or deletes the matching Google Calendar event and texts the caller the outcome through Twilio. It finds the event by the caller's phone number and the event ID returned in the lookup.
Where do messages and call outcomes go?
Message-taking and unknown requests are appended to Google Sheets with caller details. Booking and change outcomes are returned to Vapi so the assistant can confirm them in the call.
Is this a hosted service or a template?
It is an n8n workflow you import and run on your own n8n instance. You own the setup, credentials and maintenance rather than paying a per-seat receptionist service.
