I had no problem getting omniauth-ebay-oauth (https://github.com/evilmartians/omniauth-ebay-oauth) working with Devise, but when Ebay hits the callback I've got a code, but I'd expect the gem to also exchange the code for an auth_token.
Is there something I'm missing with the gem? I don't see anything in the documentation that mentions swapping the code for an auth_token.
I can get the auth_token by doing an HTTP post in the controller, but it seems like a bit of a wasted usage of the gem.
