 So According to the Codex and a 12 Gold Badge wordpress.stackexchange
 member the following code should work, but it does not I think there is a
 bug in the add_action handler for 'wp_ajax' because the action is never
 being run.

 So this is my simple test case:

 {{{#!php
 <?php
 class testClass {

     public function __construct(){
         echo "hello world";
         add_action('wp_ajax_beacon_podio-get_apps', array($this,
 "get_apps"));
     }

     public function get_apps(){
         if(isset($_POST['app_id'])){
             $app_id = $_POST['app_id'];
             die("Request is valid");
         }else{
             die("Invalid request");
         }
     }
 }
 new testClass();
 }}}


 Testing with request to from browser with logged in admin account:
 /wp-admin/admin-ajax.php?action=wp_ajax_beacon_podio-get_apps

 Expected Result
 {{{
 hello worldInvalid request
 }}}

 Actual Result

 {{{
 hello world0
 }}}

 The question an answer that made me think this is a bug:
