question

I have developed a skill and deployed using ASK CLI. The skill works, the in skill purchasing GET request is where I have trouble. I am getting the Exception on my GET request: "There was an error with the connection to amazonException: The remote server returned an error: (403) Forbidden."

This is the GET request in C#. I have verified the apiAccessToken is being rendered where I use it, however, I'm not sure if I'm adding the headers correct for a GET request (maybe POST?):

        public static string GETRequestHeaders(MySkillRequest request)
        {
            string responseText = "";
	string requestUri = @"https://api.amazonalexa.com/v1/users/~current/skills/~current/inSkillProducts";
            advancedClient = WebRequest.Create(requestUri) as HttpWebRequest;
            advancedClient.Method = "GET";
            advancedClient.ContentType = "application/json";
            advancedClient.Headers["Accept-Language"] = "en-US"; // Need to receive this from request, add locale property to MySkillRequest class.
            advancedClient.Headers["authorization"] = request.Context.System.apiAccessToken;


            responseText = advancedClient.RequestUri.ToString();
            responseText += advancedClient.RequestUri.Query;
            responseText += advancedClient.Headers.ToString();


            HttpWebResponse response;
            try
            {
                using (response = advancedClient.GetResponse() as HttpWebResponse)
                {
                    StreamReader str = new StreamReader(response.GetResponseStream());
                    responseText += str.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                responseText += "There was an error with the connection to amazon";
                responseText += "Exception: " + ex.Message;
            }
            return responseText;
        }
