I can perfectly add an event with Google Calendar API V3 as described in https://developers.google.com/google-apps/calendar/recurringevents but I can't figure how to start on the update event process.
I guess I have to select the event (I do have the event ID stored on my DB) and then set the parameters and call an update event. But don't know where to start...
There seems to be very few tutorials around. Any ideas please?
