Fetch the friend activity Spotify feed.

Note: don't know how to code? Check the extra info at the bottom!

Overview

The Spotify API doesn't include a way to fetch the friend activity feed that's available on the right of the desktop app.

There's an issue on the spotify/web-api repository about that, where a number of people request access to this endpoint since 2015, but it was closed this summer 2020 without any plan to give access to this feature through the official API.

Because I want to fetch this data and I don't like being told no, this repo is a wrapper around the unofficial API that the app calls to fetch the friend activity feed.

Since the calls are pretty trivial, it's mostly there for public documentation purpose rather than to really be used as a library, but I still made it available on npm in case you quickly want to put together something with this.

The only dependency is node-fetch to make HTTP requests.

Usage

To use this API, you need to get a web player access token, not a regular API access token, so you can't use the official API way of logging in, getting and refreshing tokens.

The good news is that if you don't mind logging in on the web player and refreshing a value in your code once a year, it's actually quite easier than the official OAuth way. More on that below.

const buddyList = require('spotify-buddylist')

async function main () {
  const spDcCookie = 'put your cookie here'

  const { accessToken } = await buddyList.getWebAccessToken(spDcCookie)
  const friendActivity = await buddyList.getFriendActivity(accessToken)

  console.log(friendActivity)
}

main()

The output looks like:

{
  "friends": [
    {
      "timestamp": 1600773735000,
      "user": {
        "uri": "spotify:user:shaktirockgym",
        "name": "shaktirockgym"
      },
      "track": {
        "uri": "spotify:track:51xHvAUYQfhY29GcGlBM0n",
        "name": "Piano Sonata No. 16 in C Major, K. 545 \"Sonata facile\": 1. Allegro",
        "imageUrl": "http://i.scdn.co/image/ab67616d0000b273bf4b533ee6e9634a6fcd8882",
        "album": {
          "uri": "spotify:album:1XORY4rQNhqkZxTze6Px90",
          "name": "Piano Book (Deluxe Edition)"
        },
        "artist": {
          "uri": "spotify:artist:4NJhFmfw43RLBLjQvxDuRS",
          "name": "Wolfgang Amadeus Mozart"
        },
        "context": {
          "uri": "spotify:user:spotify:playlist:37i9dQZF1E4riV8HyBkA7r",
          "name": "Wolfgang Amadeus Mozart Radio",
          "index": 0
        }
      }
    }
  ]
}

sp_dc cookie

This is the only value that you need for this to work. After you login on the web player (which I don't automate because reCAPTCHA), you get a bunch of cookies, including one named sp_dc.

Seems like it's valid for one year, and with just that value you can call anytime an endpoint that gives you a refreshed, elevated API access token, that, unlike the official API ones, will let you query the undocumented endpoint that retrieves the friend activity.

Usage with spotify-web-api-node

You might already be using the spotify-web-api-node package to use the official API. For convenience, I included a method to wrap it to include the getWebAccessToken and getFriendActivity methods on it.

Using it that way, you can leverage the same elevated token for all the official API requests as well.

const SpotifyWebApi = require('spotify-web-api-node')
const buddyList = require('spotify-buddylist')

const api = buddyList.wrapWebApi(new SpotifyWebApi({ spDcCookie }))

const tokenResponse = await api.getWebAccessToken()
api.setAccessToken(tokenResponse.body.accessToken)

const friendActivityResponse = await api.getFriendActivity()
const friendActivity = friendActivityResponse.body

Should your script run more than the token response's accessTokenExpirationTimestampMs (currently an hour), I would suggest implementing token refresh logic which is just calling getWebAccessToken and setAccessToken again like above.

Don't know how to code?

If the documentation above doesn't make much sense to you, here's a couple extra information you might find useful. 🙏

Because spotify-buddylist is a library, it's meant to be used by other programs, and it doesn't makes any assumption on how it's going to be used. You're free to code a program that automatically populates another playlist, sends you a notification when a specific friend plays a specific song, feeds an online spreadsheet, or just appends to a local file.

But don't worry, if you don't know how to code, you can still use the example that just displays the data when you run it. The following steps will show you how to do that.

Installing

Because this library is built with Node.js, you'll need to install it first.

Then, download the archive for this repository and extract it.

Open a terminal, go in the spotify-buddylist directory that you just extracted, and run:

npm install

This will install the extra dependencies needed for the program to run.

Fetching the cookie

Then you'll need to grab your sp_dc cookie from Spotify. This is a requirement because Spotify doesn't allow third-party apps to get the friend activity feed, so this cookie allows us to pretend that we're the Spotify app itself to get access to that data.

For that, login on the web player and open your browser's web developer tools. It's usually in "settings", "more tools", "developer tools". In that pane, go in "application", "storage", "cookies", https://open.spotify.com (or something close to that depending on your browser).

You'll find a cookie named sp_dc. Copy its value.

Running the example

In the spotify-buddylist directory, open example.js with any text editor, and paste the cookie value in place of the text "put your cookie here".

Now, you can run the following command to execute the script:

node example.js

This will display the JSON response from Spotify (once).

If you want to run it periodically, you can uncomment the last line of the file (remove the // from the beginning of the line and save the file) and run the above command again. Now the script will run indefinitely, fetching new data every minute and appending it to the terminal output.

That should be enough to get you started! 🎉

If you want to do more things with that, you might want to learn a little bit of JavaScript. Programming is powerful, and will allow you to do the things that you want to do with your computer, instead of being limited to the things that someone else decided that you should be able to do. Enjoy!
