Note: Providers can only connect their accounts and select the calendar for syncing. They cannot modify the mapped fields.

 

Set up Google Calendar for Staff Members

Staff members can use Google Calendar only if they can edit Apps and Integrations. The syncing of bookings to a staff member’s Google Calendar is also dependent on their permissions, such as the ability to view upcoming bookings and job history.   

 

Stop Syncing on Google Calendar

To stop syncing on Google Calendar:

  1. Disable Google Calendar to stop syncing for all users.

Image
  1. Remove the Google account from “Settings > Apps & Integrations > Google Calendar Integration > Google Calendar”. Syncing will stop once the account is removed.

You can change your Google account at any time by following the steps to connect to a new account.

Handling Sync Errors

If any syncing errors occur:

  1. Error Notification: You will receive an email notification detailing the error.

  2. Retry Sync: Inside the notification, click the “Retry Sync” button. You will be redirected to the bulk sync page with the dates of the failed events.

  3. Error Messages: If the error persists, error messages will appear in the error toaster.

You can manage these notifications in Settings > Notifications > Emails > Admin > General. Additionally, SMS notifications are available under Settings > Notifications > SMS > Admin > General.   

Image

For staff, the failed event notification is given under “Settings > Notifications > Emails > Staff > General”.

Staff members will also be notified about any provider syncing failures.
