doco makes reference to OAuthLogin.GetAuthorizationCode...where is this class?

Have you got the access token? Hamishjam 

I have not used the class that was uploaded by John_Dinning  so I cannot comment on whether it works or not but I have built my own class to get the access token

maybe that was why the class was removed from the online sample but like I said I have not tried using it..

If you have the access token then just create a SimpleOAuthKeyService and assign the values from the token to it and you should be able to run the following.  

let me know how you get on. If I have time I'll build a test harness and upload it to github for others that are stuck here...seriously considering leaving the .NET SDK and just using RestSharp/HttpClient to access the API

  var keystore = new SimpleOAuthKeyService();
                keystore.OAuthResponse = new OAuthTokens
                {
                    AccessToken = myobTokens.AccessToken,
                    ExpiresIn = int.Parse(myobTokens.ExpiresIn),
                    ReceivedTime = myobTokens.TokenTime,
                    RefreshToken = myobTokens.RefreshToken,
                    Scope = myobTokens.Scope,
                    TokenType = myobTokens.TokenType
                };



                // Get Company Files
                var cfService = new CompanyFileService(configuration, null, keystore);
                var companies = cfService.GetRange();

                foreach (var company in companies)
                {
                    System.Console.WriteLine(company.Name);
                    Debug.WriteLine(company.Name);
                }

Hi PhilWherrett 

To PM I think just hover over avatar and click on "Send Message" 

I have the redirect set to http://127.0.0.1  I suppose you could modify the host file so that http://desktop resolves to this or localhost but not sure why myob are recommending that. Dont you simply need a socket for the httpListener so that it know where to listen for the response?

I have this in a in a base class 

public class BaseAuthenticator
    {

        // ref http://stackoverflow.com/a/3978040
        private static int GetRandomUnusedPort()
        {
            var listener = new TcpListener(IPAddress.Loopback, 0);
            listener.Start();
            var port = ((IPEndPoint)listener.LocalEndpoint).Port;
            listener.Stop();
            return port;
        }

        public string GetRedirectUri => $"http://{IPAddress.Loopback}:{GetRandomUnusedPort()}/";
        
    }

 private string GetAuthorizationCode()
        {
            var redirectUri = GetRedirectUri;
            Output("redirect URI: " + redirectUri);

            // Creates an HttpListener to listen for requests on that redirect URI.
            var httpListener = new HttpListener();
            httpListener.Prefixes.Add(redirectUri);
            Output("Listening..");
            httpListener.Start();

            // Creates the OAuth 2.0 authorization request.
            var authorizationRequest = string.Format("{0}?response_type=code&scope=CompanyFile&redirect_uri={1}&client_id={2}",
                AuthorizationCodeEndpoint,
                System.Uri.EscapeDataString(redirectUri),
                ClientId);

            // Opens request in the browser.
            System.Diagnostics.Process.Start(authorizationRequest);

            // Waits for the OAuth authorization response.
            var context = httpListener.GetContext();
            var response = context.Response;


          
}

then get the response and parse it for the code

happy to give you the whole code if you're still stuck
