I am trying to make a api call to " https://api.getresponse.com/v3 " with header "X-Auth-Token: api-key jfgs8jh4ksg93ban9Dfgh8" i already did it with RestSharp library bellow but somehow this not works. So i want to try same thing with httpwebrequest. Please provide an example same request using httpwebrequest i am new to c# that's why need help. Thanks in advance

 var client = new RestClient("https://api.getresponse.com/v3");
 var request = new RestRequest("/campaigns/", Method.POST);

 request.AddHeader("Content-Type", "application/json");
 request.AddHeader("X-Auth-Token:", "api-key 948dff91a017a07f3c6");
 request.Parameters.Clear();

 var response = client.Execute(request);

Answer 1

You say you want to send a header, but you do

request.AddParameter("X-Auth-Token:", "api-key 948dff91a017a07f3c6");

Moreover you do Parameters.Clear after that. Maybe changing this to AddHeader will work?

Otherwise, please provide us with more details on what exactly does not work.
