I'm currently trying to implement the Coinbase API (as seen here: <https://coinbase.com/api/doc>) on my Ruby on Rails application using Devise and Oauth2. I've gotten authentication to work just fine, however, I now need to be able to make requests to the API using the API I just linked. For example, I'd like to use 'GET /api/v1/account/balance' to show the account balance on the users profile page. 

I've done extensive research on this issue, and haven't been able to find any explanations. I'm a bit of a newbie, so excuse me if this is a stupid question. If this information can be found elsewhere instead, could you provide a link? 

Thank you in advance!
