I have an embedded player that works by trackId but: I but I am trying to get non-technical users to embed the tracks or playlists into pages. I sometimes need to regenerate the

Solution 1:

See SoundCloud's API docs on resolve:

The resolve resource allows you to lookup and access API resources when you only know the SoundCloud.com URL.

$ curl -v 'http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/matas/hobnotropic&client_id=YOUR_CLIENT_ID'

< HTTP/1.1302 Moved Temporarily
< Location: http://api.soundcloud.com/tracks/49931.json

This request will resolve and redirect to the API resource URL for the track http://soundcloud.com/matas/hobnotropic. Just follow the redirect and you will get the representation you want. The resolver supports URLs for:

• users
• tracks
• playlists (sets)
• groups
• apps

You can take a the permalink from a user and get the track or playlist ID like so:

functiongetSoundCloudId(permalink, callback) {
  var resolve = 'http://api.soundcloud.com/resolve.json?client_id=YOUR_CLIENT_ID&url=';
  var request = newXMLHttpRequest();
  request.onreadystatechange = function(){
    if (this.readyState === 4 && this.responseText) {
      var response = JSON.parse(this.responseText);
      if (response.id) callback(response.id);
    }
  };
  request.open('get', resolve+permalink, true);
  request.send();
}

Then you use it like so:

getSoundCloudId('https://soundcloud.com/matas/sets/library-project', function(id){
  // Do stuff with the IDconsole.log(id);
})
