Dropbox: Access Your Own Account

See more Dropbox Examples

To programmatically interact with your own Dropbox account, such as for uploading, downloading, listing files, etc., go to the Dropbox app console and create an application. Then generate an access token in the online app console as shown in the screenshot below. The access token does not expire, and can be used to access your own account from your own non-web application.

The example code, located below the screenshot, shows how to list the files in the root folder.
