title: eBay API Platform Notifications - I'm not receiving all the ones I want
body: <p>I'm using the eBay API and am trying to receive the following notifications: </p>
  
  <ul>
  <li>ItemSold</li>
  <li>FixedPriceTransaction</li>
  <li>EndOfAuction</li>
  </ul>
  
  <p>However, the only notification I receive is 'FixedPriceTransaction'.</p>
  
  <p>The code I'm using to 'set' what notifications I receive, looks like this:</p>
  
  <pre><code>    $opts = array(
          'ApplicationDeliveryPreferences' =&gt; array(
              'ApplicationEnable'  =&gt; 'Enable',
              'ApplicationURL'     =&gt; 'http://my.domain/ebay_notifications.php',
          ),
          'UserDeliveryPreferenceArray' =&gt; array(
              'NotificationEnable' =&gt; array(
                  'EventType'   =&gt; 'ItemSold',
                  'EventEnable' =&gt; 'Enable'
              ),
              'NotificationEnable' =&gt; array(
                  'EventType'   =&gt; 'EndOfAuction',
                  'EventEnable' =&gt; 'Enable'
              ),
              'NotificationEnable' =&gt; array(
                  'EventType'   =&gt; 'FixedPriceTransaction',
                  'EventEnable' =&gt; 'Enable'
              )      
          )
      );
  </code></pre>
  
  <p>Any idea what I'm doing wrong?</p>
