title: Get wall posts made through my Facebook application using FB's API
body: <p>I made a Facebook Application that people use to share links from my webpage to their walls, and now I need to get back a list of the posts made through it during a pediod of time (e.g. from Sep. 4th to Sep. 10th), incluiding their Post IDs.</p>
  
  <p>I am aware that I could save that information at the moment of its publication, but I need some old data that I didn't save that way.</p>
  
  <p>I have tried using FQL, but that requieres to indicate the source_id (Facebook ID of the user's wall where the post is on), which I am not able to know.</p>
  
  <p>The Graph API object for my application doesn't seem to help either, since it doesn't have a connection for the posts made through it.</p>
  
  <p>Any help would be really apreciated, even just a sign in the right direction.</p>
