I have the code below in c#, which uses RestClient. The issue is that the headers should not be case-sensitive but looks like they are.
var client = new RestClient(sMA_URL);
var request = new RestRequest(Method.GET);
request.AddHeader("cache-control", "no-cache");
//Without the line below the RestRequest adds some default header which is not acceptable by our server.
request.AddHeader("**Accept**", "*/*");
request.AddHeader("content-type", "application/json");
request.AddHeader("authorization", "Bearer "+sBearerToken);
// Make sure you deserialize this response, for further use. The best way to do this is to create a class and then fill that with the values obtained by the response but if a response is not used many times,
// you can do it the way it has been done in Bearer Token Generation
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
Console.ReadKey();
Accept header works but lower case accept does not. I can't figure out if the issue is with the service it's trying to call or with RestClient itself.
