Google calendar api CalendarList List return empty element
google-api, google-calendar-api
Solution
The solution is to share the existing calendar with the service account
`<paste-your-account-here>@developer.gserviceaccount.com`
(You can find the account in question under the `credentials` tab in Google Developers Console, it's called 'EMAIL ADDRESS')
Problem
EDIT: The original poster asked this for `C#`, but the same problem occurs regardless of the library used, and its solution is language independent. Using C# lib, ``` string service_account = "myaccount@developer.gserviceaccount.com"; var certificate = new X509Certificate2(@"pathtomy-privatekey.p12", "notasecret", X509KeyStorageFlags.Exportable); ServiceAccountCredential credential = new ServiceAccountCredential( new ServiceAccountCredential.Initializer(service_account) { Scopes = new[] { CalendarService.Scope.Calendar } }.FromCertificate(certificate)); // Create the service. var service = new CalendarService(new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "My project name", }); var calendarList = service.CalendarList.List().Execute(); IList<CalendarListEntry> items = calendarList.Items; ``` items is empty. On https://developers.google.com/google-apps/calendar/v3/reference/calendarList/list, when I try the api, I get the good result. I really don't understand why I don't have any result : seems like if the service_account do not have the same calendar as my gmail account linked to. Any suggestion ? Thanks.
