title: Facebook like and share button config — problems with fb:admins and fb:app_id
body: <p>We have a simple blog website and a Facebook page. I need to add a like and share button to the website article pages so people can like and share them with their friends.</p>
  
  <p>I have all the <code>og:</code> set correctly and the <code>article:author</code> points to my Facebook page, but the debug page is telling me that I need to set <code>fb:admins</code> and <code>fb:app_id</code> in order for it to properly display.</p>
  
  <p>It is simply not liking when I set the <code>fb:app_id</code> to my page ID, so it seems I need to create a Facebook app, but why!? Surely I don't need to create an app and have it submitted for review for my simple use case do I?</p>
  
  <p>If that is the case then there seems to be no way to set my page ID in the meta tags, which seems strange.</p>
  
  <p>When I set it to the page ID I get the following error:</p>
  
  <pre><code>Object at URL '...' of type 'article' is invalid because the given value '[page_id]' for property 'fb:app_id' could not be parsed as type 'fbid'.
  </code></pre>
  
  <p>Also, it seems to only like Facebook user IDs for <code>fb:admins</code> (I tried page ID here and it didn't like it). Why do I need to set this value? Can't it get the admin accounts from my page's admins? Why do I have to manage this list of users if it's already managed in Facebook?</p>
  
  <p>I hope someone can clear these issues up for me as I'm rather confused!</p>
  
  <p>I basically need it all fully linked up so any likes and shares are attributed to my page.</p>
