Support Client Credentials and Authorization Code Flow

[schroedermatt]

Currently, the connector can only use a manually generated oauth token and run for 60 minutes at a time.

Why? Because spotify locks down tokens created via the client_credentials grant type to only resources unrelated to a user (which isn't much).

To gain access to a user's profile and play history, the token has to obtained via the Authorization Code flow which requires the user to click "OK" on the page a page that spotify directs you to (see link below).

Options:

• Build small web app to authorize a user and kick off the connector task
• Navigate through the whole Authorization Code flow is to pull in Selenium and automate the "authorization".
