Google Calendar connector

Appointments booked over the phone land in your Google Calendar.

Cantya answers, checks your free slots, offers a time and adds the appointment to your calendar while you are busy elsewhere. Nothing to copy out by hand.

  1. Good evening, I’d like an appointment this week, ideally in the morning.
  2. Let me check the calendar. Thursday at 9:30 or Friday at 10:00, which suits you?
  3. Thursday at 9:30 is perfect.
  4. You’re booked: Thursday at 9:30, under Mrs Laurent. See you Thursday!

What does Cantya’s Google Calendar connector do?

The Google Calendar connector links Cantya’s AI phone answering to the primary calendar of your Google account. During a call, Cantya checks your busy times so it only offers free slots, then adds the agreed appointment to the calendar with the caller’s name and the reason for the visit.

Without a connector, an appointment taken over the phone goes through a note, a message or a sticky label, and then gets typed in by hand. That is where double bookings and forgotten appointments come from.

With it, the calendar you already check on your phone fills up call after call. If a customer calls back to move or cancel, Cantya updates the event in the same way.

What Cantya reads

  • Busy and free, nothing elseCantya asks for your primary calendar’s availability each time it looks for a slot. The title, description and guests of your events are not read.
  • At the time of the callThe check happens live, call by call. An appointment you have just added by hand already blocks the slot.
  • Combined with your rulesCantya matches the calendar against your opening hours, your exceptional closures, the length of each appointment type, the buffer between two appointments and the minimum notice before an appointment (two hours by default). Offers cover the next fourteen days.

What Cantya writes

  • One event per appointmentTitled « Type: Caller’s name », for example « Consultation: Mrs Laurent ». In the description, « Appointment booked via Cantya » and the reason given on the phone.
  • The slot marked as busyThe event blocks the time, for Cantya as well as for you and the colleagues who share the calendar.
  • Changes asked for on the phoneA customer who calls back to move or cancel: the event is moved or deleted in Google Calendar.

Setup

Connecting it takes two minutes.

  1. 01Open your settings

    In your Cantya workspace, under Integrations. Only the account owner can connect a calendar.

  2. 02Connect Google Calendar

    You grant access on Google’s own sign-in page. Cantya never sees your password.

  3. 03Set your appointment types

    Length, buffer, opening hours: these decide which slots are offered. The calendar only says what is already taken.

  4. 04Make a test call

    Call your number, ask for an appointment, and watch it appear in your calendar.

Worth knowing before you connect

  • One calendar per account

    Cantya reads and writes the primary calendar of the connected Google account. Secondary calendars and one calendar per practitioner are not supported today.

  • Appointments flow one way

    What you add in Google blocks slots. However, a Cantya appointment that you delete or move directly in Google is not updated in your Cantya workspace.

  • If access is cut off

    Access revoked or expired on Google’s side: you get an e-mail and reconnect in one click. Until then, Cantya offers slots based on your opening hours alone.

Frequently asked questions

Page updated on October 6, 2026

Can Cantya read what is in my appointments?
No. Cantya asks Google which times on your primary calendar are busy and which are free. The title, description and guests of your events are not passed on.
What happens if I add an appointment myself in Google Calendar?
The slot is blocked from the very next call: Cantya reads your calendar live each time it looks for a slot and never offers a time that is already taken.
Can a customer move or cancel their appointment over the phone?
Yes. If they call back, Cantya finds their appointment, offers a new slot or cancels it, and updates the event in Google Calendar.
Can we connect several calendars, one per practitioner?
Not today. Cantya works with the primary calendar of a single Google account. For a practice with several practitioners, the simplest option is a shared Google account whose primary calendar serves as the common schedule.
Does the Google Calendar connector cost extra?
No, it is included in every plan at no extra cost. You connect and remove it whenever you like from your settings.
Where are the permissions to my calendar stored?
With Composio, our integration subprocessor, bound by the European Commission’s standard contractual clauses. Cantya only keeps the ID of the event it created, so it can move or cancel it.
What if I use Outlook rather than Google?
Cantya also connects to the Outlook calendar of a Microsoft 365 work account, on the same principle: it reads the busy slots, then writes the appointment.

Your calendar fills up while you work.

Create your account, connect Google Calendar, and make the first test call straight away.
