Can't connect to RESTlet api

I've been trying to connect to my Restlet api via visual studios through token based authentication. So far I have been unable to do so. I have all of the tokens I need, but I keep getting rejected.

I've been following the setTokenPassport from SuiteTalk, but if you could provide a location for me to find good documentation I would appreciate it! Below is the code I have thus far. If you see anything wrong with it, please let me know!

             string restletUrl = {My url};              string nlAuthHeader = WsHelper.generateNLAuthHeader(_service.tokenPassport);              var parameters = new List<KeyValuePair<string, string>>();              string response = WsHelper.getByRestlet(restletUrl, nlAuthHeader, parameters);            public static string generateNLAuthHeader(TokenPassport passport)          {              string header = String.Format("OAuth oauth_signature='{0}', oauth_version='{1}', oauth_nonce='{2}', oauth_signature_method='{3}',"                  + "oauth_consumer_key='{4}', oauth_token='{5}', oauth_timestamp='{6}', realm='{7}'",                  passport.signature.Value, "1.0", passport.nonce, passport.signature.algorithm, passport.consumerKey, passport.token, passport.timestamp, passport.account);                return header;          }  private void setTokenPassport()          {              /* Replace text with the information generated by the integration and token records */              string accountId = "xxx";              string consumerKey = "{token}";              string consumerSecret = "{token}";              string tokenId = "{token}";              string tokenSecret = "{token}";                _service.tokenPassport = WsHelper.generateTokenPassport(accountId, consumerKey, consumerSecret, tokenId, tokenSecret);          }            public static
