Using HTTPCaller with Body

HI,

I've not used the HTTPCaller using a POST request and body attribution.

The API call constructed by the developer has been provided like this:

var client = new RestClient("https://sww.smartchartapi.co.uk/api/Authentication/request");

client.Timeout = -1;

var request = new RestRequest(Method.POST);

request.AddHeader("Content-Type", "application/json");

request.AddHeader("Cookie", "ASP.NET_SessionId=xcqkvogm2bp2yxshsgx1ncbg; AspxAutoDetectCookieSupport=1; __AntiXsrfToken=e680dfae824a472088c01d6672ba8471");

var body = @"{

" + "\\n" +

@"  ""username"": ""SWWAPI"",

" + "\\n" +

@"  ""password"": ""***""

" + "\\n" +

@"}";

request.AddParameter("application/json", body,  ParameterType.RequestBody);

IRestResponse response = client.Execute(request);

Console.WriteLine(response.Content);

I've set up the HTTP caller like this but am getting a bad result. Any ideas what I am doing wrong?
