Unclear about PKCE and .NET SDK

Hi again Greg-DB ,

   I've been reading through the doco, and I've found what's confusing me...

   In the examples you've given, a RedirectURI is being used, but I'm not using that - I'm not launching the browser from the app, I'm just going directly to the authorise link from a shortcut in the browser and then copying the code into the app. So I'm not doing the steps from lines 183-198, I'm picking up the process from line 199 - ProcessCodeFlowAsync, and I've been doing this "ProcessCodeFlowAsync(Code,APIkey,AppSecret)".

   But the info for that says...

"

Declaration

public Task<OAuth2Response> ProcessCodeFlowAsync(string code, string appKey, string redirectUri = null, HttpClient client = null)

"

So, since the RedirectURI is optional, and I've opted out, that looks to me like I can just call ProcessCodeFlowAsync(code,appkey) and that's it? Don't need to use the secret at all now?

   Ah! I think I have it now (in fleshing this out a bit). I've used DropboxOAuth2Helper.ProcessCodeFlowAsync(Code,APIkey,AppSecret) to date, but now I would use PKCEOAuthFlow.ProcessCodeFlow(Code,APIKey) and the rest is done automagically? The same method name in 2 different classes had me thinking it was the exact same method, and thus the confusion. I think I just need to convert to using the latter instance now?

thanks,

  Donald.
