I'm currently having issues with a HttpWebRequest/Response when I'm trying to make calls to an API.
The API use JSON/Ajax to make calls, but I need to make the calls through HttpWebRequest/Response which I don't fully understand and I think I'm passing the wrong access token.
Here's my current code, which I got from a tutorial:
byte[] buffer = Encoding.ASCII.GetBytes("username=User&password=Password");
HttpWebRequest WebReq =(HttpWebRequest)WebRequest.Create("http://api40.maildirect.se/User/Authorize");
WebReq.Method = "POST";
WebReq.ContentType = "application/x-www-form-urlencoded";
WebReq.ContentLength = buffer.Length;
Stream PostData = WebReq.GetRequestStream();
PostData.Write(buffer, 0, buffer.Length);
PostData.Close();
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
var status = WebResp.StatusCode; (returns OK)
Stream _Answer = WebResp.GetResponseStream();
StreamReader Answer = new StreamReader(_Answer);
//Here I try to make another request, do I need to make another instance?
WebReq = (HttpWebRequest)WebRequest.Create("http://api40.maildirect.se/Contacts?&select=ContactId,FirstName,LastName");
WebReq.Method = "GET";
WebReq.ContentType = "text/json; charset=utf-8";
WebReq.Headers.Add("Authorization", Answer.ReadToEnd());
HttpWebResponse WebResp2 = (HttpWebResponse)WebReq.GetResponse();
^ This is where it breaks because I'm not authorized.
And the only useful documentation from the API is that I need to pass the access token when making additional calls, but I suspect I'm passing the wrong token.
Thanks in advance

I was sending the HttpWebResponse as the token, instead of the string that resulted from the StreamReader. I created a new variable called token with this string value and added it to the header "Authorization" as should be.
byte[] buffer = Encoding.ASCII.GetBytes("username=Username&password=Password");
HttpWebRequest WebReq = (HttpWebRequest) WebRequest.Create("http://api40.maildirect.se/User/Authorize");
WebReq.Method = "POST";
WebReq.ContentType = "application/x-www-form-urlencoded";
WebReq.ContentLength = buffer.Length;
Stream PostData = WebReq.GetRequestStream();
PostData.Write(buffer, 0, buffer.Length);
PostData.Close();
HttpWebResponse WebResp = (HttpWebResponse) WebReq.GetResponse();
//This token variable was something I missed creating and it also had to get the " removed to work properly.
var token = new StreamReader(WebResp.GetResponseStream()).ReadToEnd().Replace("\"", "");
WebReq = (HttpWebRequest) WebRequest.Create("http://api40.maildirect.se/Contacts");
WebReq.Method = "GET";
WebReq.ContentType = "application/json; charset=utf-8";
// This is where another part of the problem was, sent in the wrong type to the header, but when I replaced it with the token variable it worked like a charm :)
//WebReq.Headers.Add("Authorization", WebResp.ToString());
WebReq.Headers.Add("Authorization", token);
HttpWebResponse WebResp2 = (HttpWebResponse) WebReq.GetResponse();
