title: Facebook App ID - Multiple Site URL's
body: <p>I have a product consisting of hundreds of separate websites - each of which has a unique URL. Unfortunately it is not feasible for me to create a separate Facebook App ID for each website. Is it possible to configure one Facebook App ID that can be shared/used across all websites?</p>
  
  <p>I know it's possible with subdomains but haven't had any luck finding much information about my situation.</p>
  
  <p>Thanks!</p>
