SoundCloud Api - 如何制作（设置）播放列表收藏夹？

Is there any way to set playlist favorites in SoundCloud

For Track Favorites i am using

 SC.put('/me/favorites/'+track_id);

but its not working in playlist. It seems that "/favorites" only shows tracks and no playlists? Maybe there is another way to check if a playlist was marked as "like", but I did not find anything useful.

When Playlist getting error

{"errors":[{"error_message":"404 - Not Found"}]}

Thanks in advance.

This would work. Added callback for debugging.

SC.put('/e1/me/playlist_likes/' + playlist_id, function(data, err) {
    if(err) {
        alert(err.message);
    }
    console.log(data);
});
