title: facebook getting user id from graph api via taggable_friends
body: <p>In v1.0 API I was able to get friends with their facebook ID like this:</p>
  
  <pre><code>{
        "name": "Somename SomeSurname", 
        "id": "100007797060798"
   }
  </code></pre>
  
  <p>In the v2.0 I can use only taggable_friends to get this information, however `i must have missed something in the documentation, because the id I'm getting is like this (id is always different):</p>
  
  <pre><code>{
        "id": "AaKJ-QN8OlY3m-2DHeVnc5oQZFnx_V0ptUF8XFEstr3EcS1LltvAx0_xptve3DWc_vI1zP0s4RhVMOTk1EqDvzCHMkEqFRMIkuXtyXe5d9O1-Q", 
        "name": "Somename someSurname"
  }
  </code></pre>
  
  <p>can someone point me where I can retrieve a real ID out of this?</p>
