body: <ol>
  <li><p>User submits a form with some basic data.</p></li>
  <li><p>The data is received and treated by an action in the controller and more information that needs to remain private is added.</p></li>
  <li><p>Then I need to send a post request to an external website with all of the combined data from the controller.</p></li>
  </ol>
