What is the best method to retrieve the audio attributes of the currently playing song using the Spotify Web API?

Check out this link for more information on using the Spotify web API to access audio features of tracks.

Hello, I am currently utilizing the Spotify web API to retrieve audio features of a track. However, the API documentation only explains how to obtain audio features for a specific track based on its ID. My goal is to dynamically change the track ID to match the currently playing track. Does anyone have a solution for achieving this? Below is a snippet of the code showing the URL with the track ID at the end (e.g., 06AKEBrKUckW0KREUWRnvT).

Here is the code snippet:

$.ajax({
  url: 'https://api.spotify.com/v1/audio-features/06AKEBrKUckW0KREUWRnvT',
  headers: {
    'Authorization': 'Bearer ' + access_token
  },
  success: function(response) {
    audioFeaturesPlaceholder.innerHTML = audioFeaturesTemplate(response);
    console.log(response);
    $('#login').hide();
    $('#loggedin').show();
  }
});

Answer №1

If you're looking to access the latest information about the track currently being played on Spotify, there's a handy new endpoint available in the Spotify Web API. You can find more details about it here. This endpoint will provide you with real-time data on the current track being listened to by the user associated with the access token.

Check out the following code snippet that demonstrates how you can use both endpoints together to get the desired information. The access token utilized in this code must have the user-read-currently-playing scope enabled.

var access_token = "<YOUR_ACCESS_TOKEN_HERE>";

(async () => {
  var currentTrack = await ajax("https://api.spotify.com/v1/me/player/currently-playing");
  var audioFeatures = await ajax(`https://api.spotify.com/v1/audio-features/${currentTrack.item.id}`);
  console.log(audioFeatures);
})();

function ajax(url) {
  return $.ajax({
    url: url,
    headers: {
      'Authorization': 'Bearer ' + access_token
    }
  });
}

Answer №2

setInterval(function(){
        callAjax();
        }, 1000);
        var apiData; 
        var audioData;  
        var callAjax = function(){
         $.ajax({
            url: 'https://api.spotify.com/v1/me/player/currently-playing',
            headers: {
              'Authorization': 'Bearer ' + access_token
            },
            success: function(response) {
              currentPlayingPlaceholder.innerHTML = currentPlayingTemplate(response);

              apiData = response;
              console.log(response);
              $('#login').hide();
              $('#loggedin').show();
            }
        });
        if(apiData != undefined){
        $.ajax({
            url: "https://api.spotify.com/v1/audio-features/" + apiData.item.id,
            headers: {
              'Authorization': 'Bearer ' + access_token
            },
            success: function(response) {
              audioFeaturesPlaceholder.innerHTML = audioFeaturesTemplate(response);

              console.log(response);
              $('#login').hide();
              $('#loggedin').show();
            }
        });
        }

A new variable called apiData was created to store information about the currently playing track, accessible via item.id. Check this console log screenshot: enter image description here

In the 'item' subfolder, you can locate the 'id' key.

The original URL: was replaced with: url: "" + apiData.item.id

This modification appears to be effective and could potentially assist others in a similar situation.
