Retrieving Tokens

The images below are for Edge, but other browsers, especially Chromium-based should be very similar.

Deezer

In order to obtain your Deezer ARL, log into https://www.deezer.com/. Then open Developer Tools, and head to the Application tab. In the sidebar, open the dropdown list for Cookies and there should be an subitem https://www.deezer.com/. Click on the subitem and to find the the arl value, which should be 192 characters long. Note that you should open the dropdown for the Cookies section, not click on it.

Qobuz

If you can log in with an email (not username) and password, use that directly. Qobuz id and tokens are an alternative method of authentication.

To obtain a Qobuz id and token, log into https://play.qobuz.com/ and open Developer Tools. Head over the Application tab, open the dropdown list for Local Storage and click on the subitem https://play.qobuz.com. You should then click on the localuser JSON object in the viewing window, where you can find the fields id (7 digits) and token (86 characters).

Qobuz App Id and App Secret

Every id and token (your user account) is tied to an app id and secret (qobuz web player values).

However, the web player changes app id/secret every once in a while. This changes the id/token for all users. Before this release, you would need to go back into the browser to get your new id/token values.

To get around this, you can now save an app id/secret alongside your id/token. Now, even if the app id/secret changes, your old id/token remains working with the old app id/secret that you saved.

TLDR: If you don't want to manually get id/token values every once in a while, press Capture Current App ID/Secret on the same day you get your id/token from the browser. Remember to hit Save.

Spotify

FluentDL will automatically grab an access token from your local cookies. However, if you are not logged into the web player or there are auth issues, you may resort to developer API tokens.

This method is guaranteed to work and is more reliable. These tokens (client ID and client secret) can be created for free through the Spotify Developer Dashboard.

Step 1. Create an app

An app provides the Client ID and Client Secret needed to request an access token.

To create an app, go to your Dashboard, click on the Create an app button and enter the following information:

  • App Name: enter any value you wish
  • App Description: enter any value you wish
  • Redirect URI: Does not matter

Finally, check the Developer Terms of Service checkbox and tap on the Create button.

Step 2. Copy access token

In order to request the access token you need to get your Client_ID and Client Secret:

  • Go to the Dashboard
  • Click on the name of the app you have just created
  • Click on the Settings button (upper right) image

The Client ID can be found here. The Client Secret can be found behind the View client secret link. image

Then, you may enter these two values into FluentDL.
