The format bytes={start_byte}-{end_byte} can be used to specify what section of the file to download.

The URL, and optional password, for the shared link of this item.

This header can be used to access items that have not been explicitly shared with a user.

Use the format shared_link=[link] or if a password is required then use shared_link=[link]&shared_link_password=[password].

This header can be used on the file or folder shared, as well as on any files or folders nested within the item.

The unique identifier that represents a file.

An optional access token that can be used to pre-authenticate this request, which means that a download link can be shared with a browser or a third party service without them needing to know how to handle the authentication. When using this parameter, please make sure that the access token is sufficiently scoped down to only allow read access to that file and no other files or folders.
