Dropbox Community ModeratorThe Dropbox API doesn't offer a way to get an access token automatically, just from an app key and secret. If you need "background", sometimes called "offline", access like this, you should get and store the refresh token like you described. The refresh token doesn't expire by itself (though can be revoked on demand), so you can store and re-use that to get new access tokens as needed, without manual user interaction.
Is this achievable via the .NET client or only via straight http calls?

tribalneck2000 All of the functionality discussed above is available both via the API v2 HTTPS endpoints themselves, as well as the official Dropbox API .NET SDK.
Where can I find a sample of exchanging the refresh token for an access token via the .NET API? I have been looking at the repo: https://github.com/dropbox/dropbox-sdk-dotnet

tribalneck2000 You can find an example of processing the OAuth flow with the .NET SDK here. For example, it uses the RefreshAccessToken method to use a refresh token to get a new access token here.
I think I am misunderstanding what you are saying about offline access - it sounded like you can call the aquire access token once and grab the refresh token and store it permanently since it doesn't expire.. then all you have to do is call RefreshAccessToken after constructing a DropBoxClient with the refresh token as a param (not sure what you are supposed to put in the ctor param for the access token). That doesn't seem to work.
Actually I think I got it, read thru the source, there are ctors with just the refresh token. I had a scoping issue that was returning a 400 error. As long as the refresh token can be used forever, I think I may be good for now.

tribalneck2000 Thanks for following up. I'm glad to hear you've sorted this out. Yes, refresh tokens don't expire by themselves (though the user or app can revoke them if desired).
