I am using Google Calendar API to notify guest user from my own Google calender. I am adding events to my calendar with some guest user. But every time I make an event to that calendar with guest user, guest user have to accept invitation to get notification from that event. Is this possible to make a way so that a specific guest user need to accept invitation for the first time and then he don't need to get further invitation from that calendar??
For example: I have a calendar in my Google Calendar account named "FriendCollaboration". I may need to create 5 events today with two guest user. But I need to send them invitation maximum one time. When they accept that invitation they don't need to get further invitation from that calendar.
I am using latest Google Calendar Api.v3 with .net client. Any suggestion will be appreciable.
