Connecting Google Calendar lets your AI receptionist book a meeting for a caller during the call, straight onto the calendar you choose.

How to connect Google Calendar

Done

You’re redirected back to Allo. Allo reads your calendars, and your account appears in the connected list.

​
What your AI receptionist books

Google Calendar has no event types. Your AI receptionist creates the meeting directly on the calendar you pick for it, at the length you set:
  • Account: the Google account your agent books from. Any connected account in the workspace, including a teammate’s.
  • Calendar: which of that account’s calendars receives the events. Allo only shows calendars you can write to. If none is chosen, Allo books onto the account’s primary calendar.
  • Event duration: how long each booked meeting is. 30 minutes by default.

​
Who can connect and choose a calendar

Any team member can connect their own Google account, and any team member can pick any connected account in the workspace for their agent to book from, including a teammate’s. There’s no setup step to block on: unlike Cal.com or Calendly, a Google connection has no event type that can be left unconfigured. Picking which specific calendar within that account the agent uses, and setting the event duration, is more restricted: only the account’s owner, or an admin or manager, can change it. Everyone else sees the choice but can’t edit it.

​
Booking rules and blocked dates

Each connected Google Calendar account has its own business hours, timezone, and blocked dates, set on its integration page in Allo. Booking rules control when the agent can use them:
  • Buffer between meetings: on by default, 30 minutes.
  • Respect business hours: on by default.
  • Advance notice: on by default, 2 hours minimum before a meeting can be booked.
  • Booking window: off by default. Turn it on to cap how far out callers can book, 60 days by default.
These settings apply to the account you connect. If a teammate connects their own Google account, they set their own hours and rules independently.

​
Troubleshooting

Allo only shows calendars you have write access to in Google. Check your sharing permissions for that calendar, or use an account that owns it.
Only the account’s owner, or an admin or manager, can change which calendar an agent books into and how long its meetings are. Ask one of them to update it.
Only the person who connected a Google account can disconnect it in Allo. Ask them to disconnect it, or revoke Allo’s access directly in your Google account.
