Long term expiration Token

Hi production_tvox,

Long lived access tokens (despite existing can still be used) can NOT be issued any more. You should add in your code support for refresh token. Like the long lived access token, refresh token doesn't expire till revoke explicitly. If you are using in your application one of Dropbox SDKs, the only thing you have to do is initialization of client object properly with refresh token instead of long lived access token. The SDK in use will take care for the rest. Without SDK you have to add some refresh logic in your application, so to ensure a valid short lived access token is available whenever need.

You can avoid implementing full OAuth flow within your application with a pre-generated refresh token to be used into application (the same like long lived access token). 😉 Usable on server side applications. Take a look here for a possible way of getting such token.

Hope this helps.
