title: Google CalDAV: access to shared calendars
body: <p>Suppose I have been granted access to some other user's calendar. I can successfully view that calendar in the Google Calendar web UI under "Other Calendars".</p>
  
  <p>Can that calendar be accessed via CalDAV? If so, how?</p>
  
  <p>My CalDAV client starts looking at <a href="https://apidata.googleusercontent.com/caldav/v2" rel="nofollow">https://apidata.googleusercontent.com/caldav/v2</a> and authenticates via OAuth2. It follows the current-user-principal URL and from there to the calendar-home-set. In the calendar-home-set resource collection are the main calendar of the user and some virtual calendars (birthday/anniversaries of contacts, public holidays) but not the shared calendar.</p>
