title: How do i open up API requests to my app with devise_token_auth?
body: <p>I am using devise_token_auth in my rails app. I am looking to open up apis to my app using user specific tokens which would give them limited access to certain apis within my app.
  It should work similar to current public key and private key settings for integrating with apps like facebook, google, stripe etc.
  What should I be using? Is there any good documentation/ sample apps implementing this?</p>
