Twitter Streaming Unauthorized


#1

I have built a Twitter library for getting data from twitter apis. The REST APIs are working fine. I am getting a 401 unauthorized error for Public Streams by location. Here are the error details:

Transfer-Encoding: chunked
Cache-Control: must-revalidate,no-cache,no-store
Content-Type: text/html
WWW-Authenticate: OAuth realm=“Firehose”

The api I am accessing is : https://stream.twitter.com/1.1/statuses/filter.json?locations=34.54899790,16.3795280,55.66669990,32.1542840

Here is my code:

Uri = TwitterAPIs.PublicStreams + Query_Params.ToString();
                System.Uri APIUrl = new System.Uri(Uri);
                UriHeader = APIHelper.RequestHeaderBuilder(Credentials, APIUrl);
                //Generate Web Request & Request Header
                HttpWebRequest webRequest = null;
                webRequest = (HttpWebRequest)System.Net.WebRequest.Create(APIUrl);
                webRequest.Method = "GET";
                webRequest.ContentType = "application/x-www-form-urlencoded";
                webRequest.Headers.Add("Authorization", UriHeader);
                webRequest.Host = "stream.twitter.com";
               
                    HttpWebResponse TwitterResponse = (HttpWebResponse)webRequest.GetResponse();
                    using (StreamReader reader = new StreamReader(TwitterResponse.GetResponseStream()))
                    {
                        while (true)
                        {
                            var line = reader.ReadLine();
                            if (String.IsNullOrEmpty(line)) continue;

                            dynamic obj = JsonConvert.DeserializeObject(line);

                            if (obj.user != null)
                                Console.WriteLine(obj.user.screen_name + ": " + obj.text);

                        }
                    }
