  1. You need to understand how the concepts work by reading the documentation

    1. User takes an action in the app, such as read an article
    2. App invokes a HTTP POST to the Graph API end-point /me/action:object=Object_URL
    3. Facebook will crawl the object webpage (your WordPress page), read its meta tags and connect the object to the user via the action.

    Your action is news.reads, so you would call as follows

    POST https://graph.facebook.com/me/news.reads?article=[article object URL in your WordPress Blog]

    In order to have this work you need to set up the built action type read in your app settings: https://developers.facebook.com/apps/YOUR_APP_ID/opengraph

    news.read in app settings

    Then you must have the article type for the object set.

    Article Object

    Then you must set up an object url on your WordPress blog these are done by inserting meta tags

    <html>
    <head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# 
                  article: http://ogp.me/ns/article#">
     <meta property="fb:app_id"               content="YOUR_APP_ID"> 
     <meta property="og:type"                 content="article"> 
     <meta property="og:url"                  content="URL of this object">
     <meta property="og:site_name"            content="Name of site hosting article">
     <meta property="og:image"                content="URL to an image">
     <meta property="og:title"                content="Name of article">
     <meta property="og:description"          content="Description of object"> 
     <meta property="article:published_time"  content="DateTime"> 
     <meta property="article:modified_time"   content="DateTime"> 
     <meta property="article:expiration_time" content="DateTime">
     <meta property="article:author"          content="URL to Author object">
     <meta property="article:section"         content="Section of article">
     <meta property="article:tag"             content="Keyword">
    </head>
<body>
    <!-- main article body -->
</body>
</html>

    So you would put these in your header.php or index.php file based on your theme setup. Then you would have to insert functions and if statements based on your theme setup such as

    The URL of the post 

    <meta property="og:url" content="<?php the_permalink() ?>"/>

    A single post title

    <meta property="og:title" content="<?php single_post_title(''); ?>" />

    Then you need to lint this url to ensure you have setup properly, you can do this via 

    http://developers.facebook.com/tools/debug

    Once you are sure the meta tags are set properly you need to test the action as mentioned earlier

    POST https://graph.facebook.com/me/news.reads?article=[article object URL in your WordPress Blog]

    If everything is set this should return the id of the action.

    Then you must implement the logic for authentication using the JS SDK

    <div id="fb-root"></div>
  <script>
    window.fbAsyncInit = function() {
      FB.init({
        appId      : '[YOUR_APP_ID]', // App ID
        status     : true, // check login status
        cookie     : true, // enable cookies to allow the server to access the session
        xfbml      : true  // parse XFBML
      });
    };

    // Load the SDK Asynchronously
    (function(d){
      var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
      js = d.createElement('script'); js.id = id; js.async = true;
      js.src = "//connect.facebook.net/en_US/all.js";
      d.getElementsByTagName('head')[0].appendChild(js);
    }(document));
  </script>

    and the login button plugin

    <fb:login-button show-faces="true" width="200" max-rows="1" scope="publish_actions">
    </fb:login-button>

    Either in a functions.php file or directly within the single.php and index.php pages

    From there you must create a function to call the action below on page load

    <script type="text/javascript">
  function readArticle()
  {
      FB.api(
        '/me/news.reads',
        'post',
        { article: 'http://yourwordpress.com/site/' },
        function(response) {
           if (!response || response.error) {
              alert('Error occured');
           } else {
              alert('Article read was successful! Action ID: ' + response.id);
           }
        });
  }
  </script>
