 <!--
  To securely communicate between our Accept Hosted form and your web page,
  we need a communicator page which will be hosted on your site alongside
  your checkout/payment page. You can provide the URL of the communicator
  page in your token request, which will allow Authorize.Net to embed the
  communicator page in the payment form, and send JavaScript messaging through
  your communicator page to a listener script on your main page.

  This page contains a JavaScript that listens for events from the payment
  form and passes them to an event listener in the main page.
