Hi @ketanapatel,

Long lived access token is outdated and deprecated in Dropbox API. Generation of new long lived access token is already dropped, despite of an existing can still be used. So, if you have some already generated token, you can keep it "forever" (may be not exactly, but...). For generation of new long lived access token - forget it.

For long term access without additional user interaction (like was for long lived access token), refresh token can be used to keep access token validity. You can get idea, about refresh token, taking a look here. 😉

Hope this helps.

@ketanapatel Здравко is correct, Dropbox is in the process of switching to only issuing short-lived access tokens (and optional refresh tokens) instead of long-lived access tokens. You can find more information on this migration here.

Apps 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. You can find more information in the OAuth Guide and authorization documentation.

For 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. (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.
