title: Insert Calendar by URL, Google Calendar API
body: <p>According to <a href="https://developers.google.com/calendar/v3/reference/calendarList/insert" rel="nofollow noreferrer">this</a> documentation, you can insert a calendar into a users calendar list by a calendar id. However, what if the calendar is coming from a different endpoint? The endpoint we have downloads a <code>.ics</code> file. </p>
  
  <p>This can be achieved manually by going to <a href="https://calendar.google.com/calendar/r/settings/addbyurl" rel="nofollow noreferrer">https://calendar.google.com/calendar/r/settings/addbyurl</a> and pasting in the specified url. How can I achieve this using the API?</p>
