The Dropbox API doesn't support If-Modified-Since/Last-Modifed header functionality.
Instead, to check if a file has changed, you can store/check the 'rev' value in the file's metadata. For example, you can call /2/files/get_metadata and store the returned 'rev' value. When you call back later, if the 'rev' value has changed, you know the file changed. This also works with any call where you get file metadata back, e.g., /2/files/list_folder[/continue], etc. Likewise, you can use the 'content_hash' value to check if the file data itself is different.
The file metadata also contains 'client_modified' and 'server_modified' information indicating when the file changed.
