title: Facebook Graph API Integration into my API
body: <p>I am developing an API that will be used solely for a mobile app, the mobile app allows users to log in via facebook and grant the app permission to access the users facebook friends list and post on their wall.</p>
  
  <p>However I have some confusion as to where I integrate into the API and where the app developers integrate. I assume the login with facebook part is done by the app developers, who then pass the facebook access token into the API for it to store/retrieve friend list and make posts on the users wall. </p>
  
  <p>Am I correct in assuming this? And if so can I test my part the implementation by retrieving friends list without having the app developers do their part first?</p>
  
  <p>Thanks</p>
