Survey Monkey is Giving me an Invalid Authorization in Request Header Error

I am using the .NET HttpClient in xamarin forms to try to connect to survey monkey. I am new to HttpClient, Xamarin, REST, and survey monkey so I could be making mistakes anywhere or everywhere.

I've had some success using the survey monkey examples with curl and I am trying to convert that to C# code with HttpClient.

I have some "test code" like

HttpClient httpClient = new HttpClient();
Uri        uri        = new Uri("https://api.surveymonkey.net/v2/surveys/get_survey_list?api_key=humkanu389g5dp9tvsdrh8fv");
HttpContent content = new StringContent(String.Empty,Encoding.UTF8,"application/json");

httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization","Bearer XXXXXXXXX");
httpClient.Timeout = TimeSpan.FromSeconds(10);

HttpResponseMessage response = Task.Run(() => httpClient.PostAsync(uri,content)).Result;

String responseContent = Task.Run(() => response.Content.ReadAsStringAsync()).Result;

In my code, I have replaced the XXXXXXX's with my authorization token.

But I am getting a response like

{"status":1,"errmsg":"Invalid \"Authorization\" data in request header"}

I am wondering if I am handling the AuthenticationHeaderValue() part wrong. Or something else?

General Kandalaft really pointed out the problem--which in retrospect was obvious, but I want to post the final code here in case someone else is trying this.

I ended up fixing the AuthenticationHeaderValue as pointed out above. Then I ran into a problem because my request content was an empty string. I put in some json text from an example and it worked. So the final code

HttpClient httpClient = new HttpClient();
Uri        uri        = new Uri("https://api.surveymonkey.net/v2/surveys/get_survey_list?api_key=humkanu389g5dp9tvsdrh8fv");
HttpContent content = new StringContent ("{ \"fields\": [ \"title\", \"date_modified\" ] }",Encoding.UTF8,"application/json");
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer","XXXXXX");
httpClient.Timeout = TimeSpan.FromSeconds(10);

HttpResponseMessage response = Task.Run(() => httpClient.PostAsync(uri,content)).Result;

String responseContent = Task.Run(() => response.Content.ReadAsStringAsync()).Result;

Your header is not in the correct format, you have "Authorization bearer XXXXX" as the value. So it looks like this:

Authorization: Authorization bearer XXXXX

I'm not sure why based on your code, you should debug and see the value you are sending out. But it should be:

Authorization: bearer XXXXX

My assumption is AuthenticationHeaderValue is doing something you're not expecting. Searching the docs it looks like you're doing it right - so I'm not sure exactly what's wrong with the C# code, just that the header you're sending out is not correct.
