Apple Music API Token Guide

This guide helps you extract a developer token dynamically from Apple Music's public site (https://beta.music.apple.com) and use it to access metadata for songs or albums via Apple’s internal amp-api.

Disclaimer

The unofficial method of scraping tokens from the Apple Music website is not sanctioned by Apple and is subject to break without notice if the website's structure is updated. For production applications, the official developer token method is strongly recommended due to its stability and reliability.

How It Works

The process can be broken down into two main steps:

Find the Core JavaScript File: The initial step is to fetch the HTML of the Apple Music beta website (https://beta.music.apple.com). Within this HTML, we look for a reference to a specific JavaScript file, typically named in a pattern like index-legacy-[hash].js. This file contains the necessary logic and, more importantly, the token.

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

Separate big codebases into multiple repositories.

My note below is based on https://gist.github.com/readywater/49a9fbc415141aeb02d2f1e15e643f70 but modifed it to make it work for me in 15th Aug 2021, Remarkable 2 version 2.8.0.98.
