The get_temporary_upload_link API endpoint is now officially out of preview and available for production use. Developers can use this API call to get pre-signed upload URLs.
One of the most common actions a Dropbox integration will perform is to add new content.
The upload endpoint is used to push binary content to Dropbox. This is perfect for apps where the file is local to the machine connecting to Dropbox. However, for some types of client-server applications that integrate with Dropbox, this may be not optimal. For example, you may have a server-based application which manages all state and interaction with Dropbox and a mobile client that connects your server.
