PeopleAPI Ошибка 403 Google глючит или нет

Question

Я пробовал CreateContact после PeopleAPI, например https://developers.google.com/people/v1/write-people, но всегда получал ошибку 403 Недостаточные области проверки подлинности. Я уже установил область действия PeopleServiceService.Scope.Contacts

Ниже мой полный код

                string[] Scopes = new string[] { PeopleServiceService.Scope.Contacts }; 

            UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
            new ClientSecrets
            {
                ClientId = "xxxxxxx.apps.googleusercontent.com",
                ClientSecret = "xxxxx"
            },
            Scopes,
            "me",
            System.Threading.CancellationToken.None).Result;

         var peopleService = new Google.Apis.PeopleService.v1.PeopleServiceService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = "Test1"
        });

        try
        {
            //Create New COntact
            Person contactToCreate = new Person();

            List<Name> names = new List<Name>();
            names.Add(new Name() { GivenName = "a1test1", FamilyName = "zzz" });
            contactToCreate.Names = names;

            Google.Apis.PeopleService.v1.PeopleResource.CreateContactRequest request =
             new Google.Apis.PeopleService.v1.PeopleResource.CreateContactRequest(peopleService, contactToCreate);
            Person createdContact = request.Execute();

        }
        catch (Exception merr)
        {
            MessageBox.Show(merr.Message);                
        }

Любая помощь, пожалуйста?
