I do appreciate all of your timely assistance. I've run across other posts on here where there were multiple calls going on, and the duplication was leading to this. It consistently comes back with an invalid_grant exception. The choke point is when my routine hits the ProcessCodeFlowAsync() step. I'm using a WebView2 form to run through the process, since it can run as user-level and doesn't require local admin rights.

Taking the code that's supplied in the URI and getting the refresh token. I'm hitting a stumbling block trying to perform the second half of the initial OAuth2 process. Okay, I'm making headway recoding my project to account for the new mechanism. So worst-case a few times a day they would have to run through the OAuth process again? I realize if I just work with the raw API I could likely use static App Authentication ( ) and forego the entire OAuth process if push came to shove. These endusers have the app up all of the workday and are scanning multiple documents. And our endusers definitely don't have local admin rights to their PC's.Īlso, reviewing the sample projects, it appears as if when a token has expired the routine to acquire a new one is invoking a web browser window in order to complete the OAuth process? So every 4 hours an enduser would be guided through that process, correct? The app I have is used for uploading scanned documents from dedicated endusers. Since my client-side app is a basic Click Once deployment that runs at the user level. I'll try to ferret out the logic behind the sample code and implement it outside of the mechanism used in the sample project. Getting an Error Code: 5 - Access Denied. Apparently invoking the HttpListener.Start() method requires elevated privileges. I downloaded the SDK and compiled the OAuthPKCE project. Once it applies to your app, it would apply regardless of the 'Access token expiration' setting for your app, and that setting may no longer be available for your app. While the change began on September 30th 2021, we're releasing it gradually, so you may not have seen your app(s) affected until now. Also, note though that after the change you won't be able to create new long-lived access tokens. (If that changes, we will of course announce that ahead of time.) That being the case, you can continue using existing long-lived access token(s) without interruption, if you have any. You can find more information in the OAuth Guide and authorization documentation.įor reference, while the creation of new long-lived access tokens is now deprecated, we don't currently have a plan to disable existing long-lived access tokens.

You can find more information on this migration here.Īpps can still get long-term access by requesting 'offline' access though, in which case the app receives a 'refresh token' that can be used to retrieve new short-lived access tokens as needed, without further manual user intervention. Additionally, technically unrelated to the TLS issue, Dropbox is in the process of switching to only issuing short-lived access tokens (and optional refresh tokens) instead of long-lived access tokens.
