Authentication url

[Arater]

I am using your system by entering https://eymir.tiga.com.tr/ and also i have username and password.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://eymir.tiga.atlassian.net/rest/api/latest/issue/");
request.Method = "POST";

String authHeaer = System.Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes("username" + ":" + "password"));
request.Headers.Add("Authorization", "Basic " + authHeaer);

What is wrong this authentication, it always gives 4xx error when i change my url. I think that my url is wrong but what is the correct version of url.

Thanks :)

Error code 4xx refers to client side error. Can you clarify what are you trying to achieve?
