How to connect a Google Calendar to On-Call Optimizer

On-Call Optimizer can import availability from one or more Google calendars.

Connection process

To connect a Google Calendar to your On-Call Optimizer account follow the connection instructions. In the Select calendar provider dialog, choose Google Calendar and click Begin connection. You are then asked to sign in to Google and grant On-Call Optimizer read-only access to your calendars.

You can connect any number of Google calendars (for example work and personal) to one On-Call Optimizer account, as long as you can sign in and authorize each Google account.

Updating calendar selection

To change which calendars supply availability, follow calendar configuration.

Disconnecting

To remove a Google Calendar connection:

  1. Click your avatar at the top right of the application and choose Calendars.
  2. Click the Disconnect icon (a circled cross) at the top right of the Google connection card.
  3. Click Disconnect in the Disconnect calendar dialog to confirm.

Disconnecting also removes all availability imported from the connection’s calendars.

Required permissions and data

On-Call Optimizer asks for the smallest OAuth permission set that works, and limits how much calendar data it reads and stores.

OAuth scopes requested

Data accessed

On-Call Optimizer filters events to minimize the amount of information processed and retained.
