title: Access Facebook Messenger User Profile API in DialogFlow
body: <p>I'm building a cross-platform chatbot in Google's DialogFlow. I'd like to access the Facebook User Profile API to learn the user's first name.</p>
  
  <p>I'm struggling to find advice on how (or if) I can make this happen.</p>
