How do I authenticate using Devise in a Rails REST API App?

Question

I'm creating a Rails app which have both a GUI part, and a REST/JSON-API.

The REST/JSON API is fairly simple, and the controller returns data like this:

def get_players
    @players = Player.all
    render json: @players
end

The GUI part of the app is using Devise for authentication, and it works fine.

Now I want to add authentication for the REST/JSON Api too, how do I do that?

Also, how do I test the REST API using curl when the Authentication is added?

---- edit ----

as it turns out, Devise wasnt necessary in this case. A home-cooked token-authentication method works for now. (token created when Player is created, and returned on correct e-mail/password combo).

After getting a few tips, I found a number of great sites. There are several ways to do this, however I don't know which one is best, but these sites help a long way:
