Dropbox API OAuth 2.0 Access Token

Hi cmpl2022,

Yes, Dropbox access tokens are short lived and expire in few hours (typically 4 or so). Doesn't matter how they are received! The way to achieve long term access is usage of refresh token (offline access). In such a way you can "refresh" (create new access token programmatically, without further user interaction) whenever needed and go further in your algorithm. If you use some of the SDKs, it's implemented there already - you need just to initialize the Dropbox client object in a proper way and use it... as usual. If you drive your API calls directly, take a look here for details how it can be performed. Just don't forget to implement in your algorithm a check before each regular call if current access token is going to expire (before use it) and if so, to refresh it and use after that. You will need to store refresh token and expiration moment of the current access token in addition (to be able check if it's going to expire). 😉 That's it.

In such a way you don't need your users to drive their own account etc. and all could be done in your account only.

Hope this helps.
