title: Facebook notifications API: "This method must be called with an app access_token"
body: <p>I am trying to send a Facebook notification from my app using Graph API Explorer. So I have selected my app, POST, and entered this string after the <code>/</code></p>
  
  <pre><code>11093774316/notifications?access_token=430xxxxxx156|HU0ygMtxxxxxxxxxxxxikVKg&amp;template=Hello&amp;href=index.php
  </code></pre>
  
  <p>The access string is what I get on the "Access token debugger" and I check it is ok.</p>
  
  <p>However, I get this error message:</p>
  
  <pre><code>{
    "error": {
      "message": "(#15) This method must be called with an app access_token.", 
      "type": "OAuthException", 
      "code": 15
    }
  }
  </code></pre>
  
  <p>I would say it was working one month ago... Any ideas?</p>
  
  <p>Thanks</p>
