C# Get Access Token without browser interaction

CCLFREPORTING

I am working on .net console application to download dropbox documents

i was able to do that with the generated access token from the application configuration but it gets  expires

 

i am following sample solution from github for OAuth dropbox-sdk-dotnet/Program.cs at b5dff871d353c46dcdf61f0319a10be4ed0b8c0c · dropbox/dropbox-sdk-dotnet (github.com)

after entering ClientID and Client Secret  and clicking the approve on browser i was able to get access token

 

 

is there a way to get access token from C# without browser interaction  as i need to schedule the file download .net console application without user interaction

It is not possible to fully automate this process. This needs to be done manually by the user at least once. If your app needs to maintain long-term access without the user manually re-authorizing it repeatedly, the app should request "offline" access so that it gets a refresh token. The refresh token doesn't expire and can be stored and used repeatedly to get new short-lived access tokens whenever needed, without the user manually reauthorizing the app.

 

For the official Dropbox API v2 .NET SDK, you can find an example of using the new authorization functionality, including getting and using a refresh token, in the OauthBasic example (non-PKCE, meant for server-side apps) as well as in the OAuthPKCE example (PKCE, meant for client-side apps).
