Let’s break down what the Deezer ARL token actually is, how developers use it, and why you should treat it like a password. ARL stands for Authentication Request Link (or sometimes just a legacy term for a user session token). In technical terms, the ARL token is a unique identifier that Deezer assigns to your account after a successful login. It acts as a bearer token for API authentication.
"arl": "f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8", "downloadLocation": "/music", "bitrate": 9
It looks like this: f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8
To the uninitiated, it’s just a random string. To developers and power users, it’s the key to Deezer’s API. But with great power comes great responsibility—and significant risk.
Python scripts using deezer-py or raw requests can automate playlist backups:
If you’ve ever ventured into the world of self-hosted music downloading, Docker-based music archivers, or open-source Deezer clients, you’ve likely encountered the term ARL Token .
import requests ARL = "your_arl_here" session = requests.Session() session.cookies.set("arl", ARL, domain=".deezer.com")
