title: Web app integration with facebook ( architecture issues )
body: <p>I'm building my own social platform on top of facebook, and some advice on the architecture of my web app would be welcome.</p>
  
  <p>I need some data that is returned from the Facebook APIs, in order to get that data I know I need to make my users login with Facebook ( OAuth 2.0 ). After this is where I'm a little bit confused.</p>
  
  <p>Should I call Facebook APIs from the backend ( I'm using Python ) and then return that same data back as a response?</p>
  
  <p>Should I call Facebooks API from the front end ( browser's Javascript ) and then sent that data again to my backend?</p>
  
  <p>Once the user has authorized my app, can the backend keep getting info from facebook APIs?. </p>
  
  <p>Thanks in advance.</p>
