This guide shows how to connect Google Calendar to Clarion. Once connected, Clarion automatically writes on-call shifts to a calendar you choose and keeps them updated as the rotation changes.
Estimated time: 2 minutes. You need access to:
  • A Clarion workspace with permission to manage integrations
  • A Google account with permission to authorize third-party apps for the calendar you want to use

​
Prerequisites

  • A Google account with access to the calendar you want Clarion to write to. Any Google account works — personal Gmail, Google Workspace, or a shared account.
  • An on-call rotation defined in Clarion under Settings → Notifications. If the rotation is empty, the connection is still allowed but no events appear until you add slots.

​
Step 1 - Connect Google Calendar

  1. In Clarion, open Integrations and find Google Calendar.
  2. Click Connect Google Calendar. You’ll be redirected to Google to authorize Clarion.
  3. Review the requested permissions in Google, then click Continue.
Google redirects you back to Clarion with the connection established. Clarion now needs one more choice: which calendar to write to.

​
Step 2 - Choose a target calendar

On the Google Calendar integration page, pick where Clarion should write the on-call shifts:
  • Create a new Clarion On-Call calendar (recommended): Clarion creates a dedicated calendar in the connected Google account named Clarion On-Call. Best for teams who want a clean, isolated view of the rotation.
  • Use an existing calendar: Pick any calendar you have write access to. Best when you already have a shared team calendar.
Click Save target calendar. Clarion runs an initial sync and writes the next 12 weeks of on-call shifts. Each shift is an all-day event titled with the on-call member’s name.
The on-call member is added as an attendee on their shift, so the event also appears on their personal calendar automatically. Google emails each new attendee once when Clarion first schedules them — subsequent edits (rotation reorders, description tweaks) stay quiet.

​
What Clarion syncs

Every event Clarion writes:
  • Is an all-day event covering the full length of the shift (7 days for weekly rotations, 14 days for biweekly).
  • Has the on-call member(s) as attendees, so shifts also appear on their personal calendars.
  • Sets a 24-hour popup reminder on the shared Clarion calendar. Each attendee’s personal copy uses their own Google Calendar default reminders — you can override per-event or globally in Google Calendar settings.
  • Includes a link back to the Clarion Settings → Notifications page for context.
When the rotation changes — new member added, slots reordered, cadence changed — Clarion patches the affected events on the next sync (immediately after you save the rotation, plus a daily background pass).

​
Manually resync

On the Google Calendar integration page, click Sync now to reconcile the calendar immediately. Useful when:
  • You just updated the rotation and don’t want to wait for the automatic sync.
  • Someone deleted a Clarion event manually — resync restores it.
  • The last-sync line shows an error.

​
Reconnecting after Google revokes access

If Google revokes Clarion’s access (for example, when the person who connected removes Clarion from their Google account), the integration surfaces a Reconnect Google Calendar button on the settings page. Clicking through the OAuth flow again restores the sync — the target calendar setting is remembered, so no manual re-picking is needed.

​
Disconnect

To stop syncing:
  1. Open the Google Calendar integration in Clarion.
  2. Click Disconnect.
  3. Confirm the dialog.
Behavior depends on the target calendar:
  • If Clarion created the calendar for you, that calendar is deleted from Google along with its events.
  • If you pointed Clarion at an existing calendar, only the events Clarion added are removed. Everything else on the calendar is left untouched.
