Unclear about PKCE and .NET SDK
Hi, Firstly, I'm getting 404's on all your documentation at the moment, so I'm unable to look it up. e.g. the link https://dropbox.github.io/dropbox-sdk-dotnet/html/M_Dropbox_Api_Files_Routes_...
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...
"Processes the second half of the OAuth 2.0 code flow. Uses the codeVerifier created in this class to execute the second half.
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.

Dropbox StaffThe .NET SDK documentation is currently available here. Click the "API Documentation" link at the top to access specific classes/methods.
The PKCE flow is the right thing to use for client-side apps, such as desktop apps. The SDK will still do most of the work for you. You can find an example of using the PKCE flow with the .NET SDK here. For instance, here's where where you start the flow and have the SDK build the authorization URL (without the app secret; it handles the PKCE code verifier/secret automatically internally for you), and here's the line where it processes the result to return the access token and refresh token. From there, you can make a client (with the refresh token and app key, but not app secret) and the SDK will handle the refresh process for you automatically.
Hi Greg-DB ,
Thanks for the correct link. I'll read through that shortly, but first the documentation link that you've given in your reply here...
>The .NET SDK documentation is currently available here. Click the "API Documentation" link
is a DIFFERENT link to the "Documentation" link which is on the first page itself, and that returns a 404. Here's some screenshots showing them pointing to different places...
- this works
-this gives a 404
Thanks,
Donald.

Thanks for the note. We'll get that fixed up in the next build of that GitHub page.
