Creating a Set With Soundcloud's API

Question

I'm using Javascript to create a web app with Soundcloud's API for my portfolio. At my current stage I need to be able to create a new set (aka playlist). I was using the sample code from Soundcloud's docs:

SC.connect(function() {
  var tracks = [22448500, 21928809].map(function(id) { return { id: id } });
  SC.post('/playlists', {
    playlist: { title: 'My Playlist', tracks: tracks }
  });
}); 

But I'm getting a 422 error:

Unprocessable Entity - The request looks alright, but one or more of the parameters looks a little screwy. It's possible that you sent data in the wrong format (e.g. an array where we expected a string).

But it does not look like anything's missing.

Answer 1

The call to the SoundCloud API requires a callback function in addition to the playlist title and tracks. Your code should look like this:

SC.connect(function() {
  var tracks = [22448500, 21928809].map(function(id) { return { id: id } });
  SC.post('/playlists', {
    playlist: { title: 'My Playlist', tracks: tracks }, function(response){
      console.log(response)
    }
  });
});

Their example is, unfortunately, wrong.
