Error 404 when creating a calendar with Google Calendar Api v3 using c# .net - http-status-code-404

Question

I am trying to create a calendar using Google Calendar API v3 if it does not already exist. My implementation successfully retrieves all my calendars and events and can change calendars, but I am struggling with adding a new calendar. This is what I do in order to try to add a new calendar for the user:
...
var calendarService = new CalendarService(_authenticator);
var calendarId = "com.somedomain.somename.1234"; // Some random ID
try {
calendarManager.GetCalendar(calendarId); // No calandar found
} catch(GoogleCalandarServiceProxyException e){
// Ok, so far so good, calendar not found (that is correct) and I am here
var someCalendar = new Google.Apis.Calendar.v3.Data.CalendarListEntry {
Summary = "Some summary!",
Description = "A calendar descr.",
AccessRole = "writer",
BackgroundColor = "#E7323C",
Id = calendarId
};
calendarService.CalendarList.Insert(someCalendar).Fetch(); // Fetch to execute
}
Request generated:
insert # https://www.googleapis.com/calendar/v3/users/me/calendarList?alt=json&prettyPrint=true
RequestError:
Google.Apis.Request.RequestErrorNotFound[404]Errors [Message[Not Found]Location[-] Reason[notFound] Domain[global]]]
Weird thing is that doing a GET at https://www.googleapis.com/calendar/v3/users/me/calendarList?alt=json&prettyPrint=true does not return something, so it should be there.
I hope that there is some awesome guy/girl out there which knows what to do! I'm completely stuck.
Update
Seems like I am receiving the same 404 error on CalendarList Google Api Explorer also:
Url:
https://developers.google.com/google-apps/calendar/v3/reference/calendarList/insert
Request:
POST https://www.googleapis.com/calendar/v3/users/me/calendarList?key={YOUR_API_KEY}

Response:

- Show headers - { "error": { "errors": [ {
"domain": "global",
"reason": "notFound",
"message": "Not Found" } ], "code": 404, "message": "Not Found" } }
Does anyone know whether Google have changed the URL for this resource? And if yes, how I change the Google Calendar Api v3 to use the updated url ...?

Answer 1

Okey, my bad:
You can't create a calendar with your own identifier, the purpose of CalendarListEntry.Insert() is to insert a created Calendar into the list of calendars
So to create a new calendar one has to:
Insert a new Calendar: https://developers.google.com/google-apps/calendar/v3/reference/calendars/insert
(DO NOT add id as paramater, this will be automatically created)
Insert the ID of the calendar created in step 1 and insert it into the calendarList: https://developers.google.com/google-apps/calendar/v3/reference/calendarList/insert

Answer 2

I'm still totally confused as to Google's distinction between a Calendar and a CalendarList since the data seems to overlap. Why is a calendar considered a "secondary" calendar.

Answer 3

The next code dit the trick for me, The mentioned reference is Java not .Net and, as usual ther e are some anoying differences...
private bool createCalendar()
{
// use Google.Apis.Calendar
Calendar calendar = new Calendar();
calendar.Summary = "MyNewCalendar";
calendar.Description = "Your new Calendar";
calendar.Location = "Aadorp";
calendar.TimeZone = "Europe/Amsterdam";
try
{
// Not inserting in CalendarList but in Calendar!
calendarService.Calendars.Insert(calendar).Execute();
}
catch (Exception exception)
{
MessageBox.Show(exception.Message);
return false;
}
return true;
}
