Sync Scheduler with Google Calendar

Hello
I need to sync my users data with their Google account’s Calendar.

The GoogleCalendarHelper class needs the login credentials of the user.
How can I do the same using OAuth, beacuse there is no way users are going to share their gmail credentials.

Thanks

Hello,
currently we don’t have ready solution for sharing google calendars using OAuth autorization(GoogleCalendarHelper works with old GData protocol)
You’ll have to do authorization and retrieving data via google calendar API manually.
The best thing I can suggest at the moment is to refer to this article
