Why is Google Calendar API (oauth2) responding with 'Insufficient Permission'?

Question

I\'m doing a get request to the following URL (with {id} replaced with the id from the web interface):

https://www.googleapis.com/calendar/v3/calendars/{id}
         


        

Answer 1

https://www.googleapis.com/auth/calendar
