Desktop-App

  1. Get a new token to request authorisation:

    token = Rockstar::Auth.new.token

  3. Wait for the User to confirm that he accepted your request.

  4. Continue with “Get the session token”

Web-App

  1. Redirect the user to www.last.fm/api/auth/?api_key=YOUR_API_KEY&cb=YOUR_RETURN_URL

  2. If the user accepts, lastfm will redirect to YOUR_RETURN_URL?token=TOKEN

    token = params[:token]

  3. Continue with “Get the session token”
