Spotify’s million playlist dataset can be used to create various projects. Because of its massive dataset, it is possible to develop projects such as a music recommendation system. This tutorial will teach you how to extract various information from Spotify API.

How To Create Media Information Platform Via Spotify API?
Spotify stores data on its songs that we can access via the Spotify API. The Spotify API is a fantastic public tool that allows the use of Spotify’s wealth of music data to build various systems. So, this tutorial will extract music data using the Spotify API.
What Can We Do With The Spotify API?
The Spotify API is quite powerful, providing a wealth of information about any song or artist on Spotify. This ranges from features describing the features of the music like:
- Liveliness
- Acoustics
- Feel
- Energy
Essentially, you can extract information about artists, music, albums, tracks, get music lyrics, and more:
- Album tracks (metadata)
- Artist information
- Related data
- Available artists
- Playlist
- Searching option
- Track lyrics
- Follower info
- User profile info
I will play with a few API endpoints to make this tutorial brief. After learning the basics of connecting to the endpoint, you can play with other Spotify API endpoints.
What Is An API, And How To Use It?
If you have not used an API before, using various keys for authentication and sending requests can be a bit difficult. First, we will get keys to use. To do this, we need an account on the APILayer marketplace. This APILayer account gives you a universal API key that accesses the Spotify API.
After registration, the API key will be shown on your Dashboard.
How To Authenticate With Spotify?
You can start sending requests to the endpoint with the API access key. Here is a sample request that you can do from your terminal:
As you can see, you need to provide the API access key in the request URL as a parameter.
Here is the sample code that shows you how to integrate Spotify API into your Python application:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import requests url = "https://api.apilayer.com/spotify/album_tracks?id=id" payload = {} headers= { "apikey": "eeiu8X1HyhbH2QZq5TYgl65SYIC6MDr5" } response = requests.request("GET", url, headers=headers, data = payload) status_code = response.status_code result = response.text |
If you head over to the official documentation page, there are sample source codes available in various programming languages that show you how to utilize the Spotify API.
Moreover, you can test the API in real time with the Live API Playground.
How To Extract Tracks From A Playlist?
The first method we use to extract features from tracks in a playlist is the “playlist_tracks” method. This method gets the URI from a playlist and outputs JSON data containing all of the information about this playlist. Since its already in JSON format, you can extract any value from the object like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import requests url = "https://api.apilayer.com/spotify/album_tracks?id=id" payload = {} headers= { "apikey": "eeiu8X1HyhbH2QZq5TYgl65SYIC6MDr5" } response = requests.request("GET", url, headers=headers, data = payload) status_code = response.status_code result = response.text |
Now let’s create our Multi-platform Delphi FireMonkey application where you can deploy to Android, iOS, Windows, macOS and Linux using a single code base.
Firstly, grab your community edition of Delphi from this link and create a new multi-device application.
Here I will utilize the Native HTTP components to connect to the Spotify API. It works similarly to the Python code above, but we implement it using Delphi, which provides native and cross-platform development.
|
1 2 3 4 5 6 7 8 9 10 |
procedure TFormMain.BtnFetchTracksClick(Sender: TObject); begin NetHTTPRequest1.Get(Format('https://api.apilayer.com/spotify/album_tracks?apikey=%s&id=%s', [Edit1.Text, Edit2.Text])); end; procedure TFormMain.NetHTTPRequest1RequestCompleted(const Sender: TObject; const AResponse: IHTTPResponse); begin Memo1.Lines.Add(AResponse.ContentAsString(TEncoding.Default)); end; |
Here we are using the native HTTP client/request components to access the Spotify API and showing the response when it is fully received in the NetHTTPRequest component.
How To Extract Lyrics Of The Track Using Spotify API?
With this API endpoint, you can extract the lyrics of the songs. This is the Python code that utilizes that endpoint.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import requests url = "https://api.apilayer.com/spotify/track_lyrics?id=id" payload = {} headers= { "apikey": "eeiu8X1HyhbH2QZq5TYgl65SYIC6MDr5" } response = requests.request("GET", url, headers=headers, data = payload) status_code = response.status_code result = response.text |
Now let’s implement this in our Delphi FireMonkey application. But at this time, we will utilize the REST Debugger and REST Client components to access the Spotify API.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
procedure TFormMain.BtnGetLyricsClick(Sender: TObject); begin RESTClient1.ResetToDefaults; RESTClient1.Accept := 'application/json'; RESTClient1.AcceptCharset := 'UTF-8, *;q=0.8'; RESTClient1.BaseURL := Format('https://api.apilayer.com/spotify/track_lyrics?apikey=%s&id=%s', [Edit1.Text, Edit3.Text]); RESTResponse1.ContentType := 'application//json'; RESTRequest1.Execute; Memo1.Lines.Clear; Memo1.Lines.Add(RESTResponse1.Content); end; |
Here we are using the REST Client components to access the lyrics API endpoint. REST Client components are the best solution for integrating any RESTful services. After successful connection, the lyrics will be shown on the Memo component.
How to Fetch Artist and User Profile Data using Spotify API?
Here with this API endpoint, you can fetch artist data. This is the sample Python code for implementation example:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import requests url = "https://api.apilayer.com/spotify/user_profile?id=id" payload = {} headers= { "apikey": "eeiu8X1HyhbH2QZq5TYgl65SYIC6MDr5" } response = requests.request("GET", url, headers=headers, data = payload) status_code = response.status_code result = response.text |
Here with this API endpoint, you can fetch artist data. This is the sample Delphi code for implementation example:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
procedure TFormMain.BtnUserDataClick(Sender: TObject); begin RESTClient2.ResetToDefaults; RESTClient2.Accept := 'application/json'; RESTClient2.AcceptCharset := 'UTF-8, *;q=0.8'; RESTClient2.BaseURL := Format('https://api.apilayer.com/spotify/user_profile?apikey=%s&id=%s', [Edit1.Text, Edit4.Text]); RESTResponse2.ContentType := 'application//json'; RESTRequest2.Execute; Memo1.Lines.Clear; Memo1.Lines.Add(RESTResponse2.Content); end; |
Here we are using the same technique again. Created the REST Client component via REST Debugger and made a few changes by writing code. This time, we are using the user_profile API endpoint and giving the user ID. This fetches available information about the Spotify user. Here, in this case, you can see my profile information brought by the Spotify API.
In the above image, you can see the application in action. You can find the whole project source code from this repository [1]. Moreover, check out these latest tutorials where you can learn how to automate various tasks using powerful APIs.
