Deezer User Token ~upd~

A: Officially, no. Deezer’s terms of service (TOS) are designed for their official API and do not explicitly support the use of ARL cookies extracted from web browsers. Using your token in a third-party app is usually tolerated for personal use but is technically against the official developer TOS.

Deezer’s OAuth returns expires_in (seconds). After expiry, use refresh token.

There have been sporadic reports of Deezer's OAuth system returning a token that appears valid but does not work with any /me endpoints (such as /user/me/playlists ). When this occurs, it is likely a server‑side issue on Deezer's end. Community reports suggest that Deezer can be slow to fix these problems, so your best option is to wait and try again later, or switch to using the ARL token method instead. A: Officially, no

Before using any tool or script that asks for your Deezer token:

URL Encoding: Ensure your token is correctly encoded when sent in the header of your API requests. Deezer’s OAuth returns expires_in (seconds)

If you prefer a visual tool, extensions like the "Deezer ARL Retriever" for Microsoft Edge automate this manual browsing process. With a single click, they copy your current ARL token to the clipboard, saving you from hunting through the developer tools.

Some community sources suggest that if you request the offline_access permission during OAuth, you may receive a token with an expires=0 value, which some interpret as “never expires”. However, this behaviour is not guaranteed across all versions of Deezer's API, and relying on a token never to expire is risky.

: Allows the application to manage social features, like following other users.

Deezer utilizes the standard OAuth 2.0 protocol to issue user tokens. Understanding this flow is essential for implementing secure access in your application.
