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

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

Hi Kruts,

Sorry for the late reply, I have not been monitoring this forum. I have OAuthLogin.cs and OAuthKeyService.cs that I believe were originally included in the C# samples provided by MYOB on their github which doesn't seem to exist any more. 

As far as I know, these are unmodified and still work. Hopefully MYOB won't mind me attaching these. Perhaps they could make them accesible to others again.

Howdy kjm ,

Yep I tried to do that for the PM - but the page I get sent to doesn't render properly to allow sending anything:

Your code snippets are pretty much what I'm doing so thanks for sharing and confirming that I'm heading in the right direction :-)

I've managed to successfully get a code response and return the company files available so that's good.

Now just need to add the managing of token storage and refresh lifecycle so subsequent calls don't need to go through additional code requests.

Cheers,

Phil.

Hi Hamishjam,

The lost OAuthLogin.GetAuthorizationCode is in the zip file attached to my last post.

Let me know if you can't get access to it.

Thanks for the reply kjm.  I have the access tokens and I'm passing them into the SimpleOAuthKeyService.OauthResponse.  That side of things is fine.  I'm just getting exceptions when trying to fetch the companyfile object with the CompanyFileService from the SDK.  I suspect there may be some unexpected json or a breaking .NET 6 change that is yet to be addressed.  My next step will be to play with it in an old .NET framework and report it via GitHub I guess.

I'm also leaning towards just pulling the JSON old school style but it would be nice to not have to build that out.  MYOB is MIA...  Developer site is a jungle of 404's.

Hi kjm , there have been some recent changes to API support. For developer support, please see https://apisupport.myob.com/hc/en-us/requests/new?ticket_form_id=215283

The email address developers@myob.com has been retired. 

Also see https://apisupport.myob.com/hc/en-us/articles/5139088196751-Developer-Update-July-2022 for a summary of changes to API support. 

There is no specific statement around online/forum support.

Hi kjm,

The OAuthLogin.cs and OAuthKeyService.cs files I posted are used in my project, which is WinForms and .NET 4.8.

It's been most of 10 years since I looked at how they work, but they have done all that time for both local, network and cloud company files.

It does seem odd that MYOB have not fixed the broken links and given access to these files. I'm sure it would be to their advantage. 

There have been times when I wished that I had not used the SDK, but it did save me a lot of time and a steep learning curve initially and it has been working fine for our purposes.

thanks for digging out those files..pretty simple stuff there..just builds a webbrowser on a form and listens to the DocumentTitleChanged event of the webrowser and then extracts the code from the document. Means that the solution has to reference Windows.Forms namespace making it a little less 'transportable' instead of just calling the users default browser. 

The OAuthKeyService.cs is a little more interesting as it uses IsolatedStorage to actually write the Token to a json file. This is not the path I am heading down. I would not be storing the token anywhere except memory. Not sure why or what the advantages of peristing the token like this is instead of to memory...is this incase user/system closes and then reopens and the user/system can reuse the tokens stored locally as opposed to having to make another call to oauth server? 

Anyway I have built a test harness polling the api getting data every minute and it look like the refresh token call is handeld by the SDK. I decompiled the SDK and had a look at MYOB.AccountRight.SDK.Services.ServiceBase and it looks like it handles the expiry/refresh token. Means I just have to get the token once and leave the SDK to it. Nice. Was expecting to have to handle the refresh part myself

posting from my other now linked dev account

I have solved this myself. little bit "surprised" at the lack of support both from myob and community. maybe these forums arent that busy/alive..

anyway..got the access code and passed it in..looks like ths SDK has a problem from there on in as I am returned a Bad Request

I have built own classes to extract the tokens using a httpListener and it works fine whic his why Ican verify that I am getting the correct access code

If anyone gets stuck like I did PM and I'll be happy to share code..

Howdy Again kjm ,

I've just started on this implementation myself - sounds like we've headed down the same path using HttpListener - but I'm not sure how to handlethe redirect if the redirect Url is http://desktop as per MYOBs recommendation when creating the API Key.  I can get a code using http://localhost as a redirect Url.

I'd be keen to get code examples of your implementation if you're willing to share (I can't seem to work out how to send you a PM :-()?

Cheers,

Phil.
