I have checked every thing repeatedly and does not seem to have any issue in code or logic.



Here is the code:



var content = new FormUrlEncodedContent(new Dictionary<string, string>

"grant_type", "authorization_code",
"code", code,
"redirect_uri", redirectUri.ToString(),
"client_id", clientId,
"client_secret", clientSecret
);
string token = string.Empty;


using (var client = new HttpClient())

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
var response = client.PostAsync(tokenEndpoint, content);
var responseContent = response.Result.Content.ReadAsStringAsync();
token = responseContent.ToString();
if (!response.Result.IsSuccessStatusCode) ;


return token;


And i am getting error:



"error": "redirect_uri_mismatch",
"error_description": "Bad Request"


The Url of the above page is : http://localhost:62188/dashboard/googleSync.aspx



And in Google Console i have this Url as Authorized Return Url :



enter image description here



So what am i missing here?
