The Google Calendar extension syncs calendar events with PagerDuty. The extension integrates with Shift Agent to detect scheduling conflicts before they impact coverage, and it operates independently to support standalone scheduling needs. This integration reduces manual availability updates and maintains operational continuity while respecting scheduled commitments.

Permission Scope Details

• The Google Calendar integration connects at an account level. PagerDuty reads Out of Office events only for Google Calendar accounts with a corresponding PagerDuty user. PagerDuty identifies users by matching email addresses.
• The scope https://www.googleapis.com/auth/calendar.events.freebusy does not enable PagerDuty to view all calendar events or user data.
• PagerDuty does not store data unrelated to Out of Office events. PagerDuty stores and displays Out of Office dates and times for specific users on the PagerDuty schedule page to determine conflicts.
• PagerDuty cannot read event titles, view users on events, or write to calendars.

Calendar Event Limit

A limit of 1,000 total future calendar events exists per calendar.

Google Calendar Update Schedule

Shift Agent ingests Google Calendar data once per hour and does not immediately detect recent conflicts. Manually share out-of-office information with Shift Agent (for example, I am going to be on vacation June 13) to immediately include recent availability updates.

Use Focus Time to Block Meetings

The Focus Time event type blocks your calendar for lunch or other times to prevent meetings. This event type auto-declines events without triggering PagerDuty conflict detection.

Configure Account-Level Notification Settings

Navigate to Integrations Extensions Google Calendar to adjust notification settings.

When enabled, you can suppress Slack conflict alerts that occur during your Google Calendar Out of Office (OOO) event. Alerts outside the OOO window deliver normally. This configuration reduces noise from last‑minute OOO blocks added to schedules.
