Hi Team,
We are doing dropbox integration to upload files from salesforce to dropbox. To do this we are doing background processing and to get access token we always use "Long-lived" from the "Generated access token" section that appears under the app "Settings" tab of the Dropbox app.
Now as per the "Action required: tokens and permissions" notification we would like to know the other way that how we can get access token without user interaction to upload file in the background?
