I'm trying to setup my old ASP.NET MVC app with Xero's latest OAuth 2.0 protocol. As per the documentation, I'm using the official Xero-NetStandard library.
I can successfully redirect the user to Xero's consent page, and also get redirected back to localhost with a valid-looking code as expected. However, problems arise when I try to retrieve the Access Token.
var xeroToken = _xeroClient.RequestAccessTokenAsync( code ).Result;
When this code is executed on my localhost environment, very little seems to happen. The request just gets stuck and won't continue past this point. The only occasional error I see is a 'request timeout' after quite a few minutes.
Please understand I have looked at all the references and examples I can find, but most of them either have specific Dotnet Core stuff, or are completely out of date (the Xero client seems to have changed quite a bit since they were created 5+ months ago).
Maybe I'm going crazy but this was working as expected a couple of months ago when I started work on our new Xero integration, but now I have no clue what's wrong 😢
It looks like that function requires being called in an async fashion:
await client.RequestAccessTokenAsync(code);
