How to Add an Event in Google Calendar

var GoogleAuthenticationURL = 'https://accounts.google.com/o/oauth2/v2/auth?';
var ClientId = '353218417589-g8dsj3ras5t93fav4bt2mqucltfsdbj8.apps.googleusercontent.com';
var GoogleScope = 'https://www.googleapis.com/auth/calendar https://www.googleapis.com/auth/calendar.events https://www.googleapis.com/auth/userinfo.email';
var GoogleRedirectURL = 'https://schedulingwebapp.azurewebsites.net/Vendor/VendorSetting';
var FinalURL = GoogleAuthenticationURL + "client_id=" + ClientId + "&redirect_uri=" + GoogleRedirectURL + "&scope=" + GoogleScope + "&response_type=code&access_type=offline&prompt=consent";
if (!window.sessionStorage.getItem("historyCount"))
window.sessionStorage.setItem("historyCount", history.length);
window.location.href = FinalURL;

I have done the same task in mvc :

follow this url instruction : https://developers.google.com/calendar/v3/reference/events/insert

Follow this steps :

1) pass paramer into this method :

public Task> insertEventToVendorAccount(string AccessToken, GoogleCalendarInsertEventRequestModel model)
{
string client_id = System.Configuration.ConfigurationManager.AppSettings["client_id"];
string client_secret = System.Configuration.ConfigurationManager.AppSettings["client_secret"];
string GoogleCalendarInsertEvent = System.Configuration.ConfigurationManager.AppSettings["GoogleCalendarInsertEvent"];
string GoogleReminderTimeInMinutes = System.Configuration.ConfigurationManager.AppSettings["GoogleReminderTimeInMinutes"];
if (!String.IsNullOrEmpty(GoogleReminderTimeInMinutes))
{
int ReminderMin = Convert.ToInt32(GoogleReminderTimeInMinutes);
foreach (var item in model.reminders.overrides)
{
item.minutes = ReminderMin;
}
}
BaseDrive baseDrive = new BaseDrive();
var bsresult = baseDrive.APICallGoogleCalendarPostAsync(GoogleCalendarInsertEvent, AccessToken, model);
return bsresult;
}

2) Call api using httpclient :

public async Task> APICallGoogleCalendarPostAsync(string ApiEndPoint, string token, object model, bool IsDeSerialize = true) where T : class, new()
{
var blresult = new BLResult();
var json = JsonConvert.SerializeObject(model);
var modelobject = new StringContent(json, UnicodeEncoding.UTF8, "application/json");
try
{
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, ApiEndPoint);
request.Content = modelobject;
request.Headers.TryAddWithoutValidation("Content-Type", "application/json");
Client.DefaultRequestHeaders.Accept.Clear();
//client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
if (token != string.Empty)
{
Client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
}
var result = await Client.SendAsync(request).ConfigureAwait(false);
if (result.IsSuccessStatusCode)
{
blresult.Success = true;
if (IsDeSerialize)
blresult.Value = JsonConvert.DeserializeObject(
await result.Content.ReadAsStringAsync());
}
else
{
//ErrorLogService.WriteLog("Response From API:" + ApiEndPoint + Environment.NewLine + await result.Content.ReadAsStringAsync());
blresult.Success = false;
blresult.ResultMessage = result.ReasonPhrase;
}
}
catch (WebException wex)
{
var errorResponse = new StreamReader(wex.Response.GetResponseStream()).ReadToEnd();
var jsonErrorResponse = JObject.Parse(errorResponse);
var errorCode = jsonErrorResponse["error"].ToString();
}
catch (Exception ex)
{
throw;
}
return blresult;
}

Sorry for late reply
Pass this request parameter while then you will get access token.
Thanks
