Dropbox Staffdbmt As Здравко indicated, you would need a refresh token to maintain long-term unattended access.
Dropbox issues short-lived access tokens, which expire after a few hours, and optional refresh tokens, which don't expire. Apps can get long-term access by requesting "offline" access, 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. Refresh tokens do not expire automatically and can be used repeatedly. You can find more information in the OAuth Guide and authorization documentation. There's a basic outline of processing this flow in this blog post which may serve as a useful example.
The official Dropbox SDKs can also handle the refresh process for you automatically. If you're using one of the official Dropbox SDKs, refer to its corresponding documentation and examples for information on how to use it.
