Hey @Ynoooos,

To do this requires quite a bit of coding. You’d need to leverage the Window.postMessage API.

This would also involve handling the message on the host page.

For example, if this message was posted on a button click the setup would look something like this:

<script>

  const  buttonId = "#lp-pom-button-9";

  const  hostDomain = "http://unbouncepages.com/";

 

 document.querySelector(buttonId).onclick =  function () {

   parent.postMessage(JSON.stringify("variable"), hostDomain);

 };

</script>

On the page hosting the popup, code will also need to be added to handle receiving the message.

<script>

  // This will need to be specific to the URL for your popup

  const  popupOrigin = "http://f26e7782694e41398352088f013af031.pages.ubembed.com/";



  // On receiving message from the Convertable set a cookie

  window.onload =  function () {

     function   handleMessage (e) {

       var  eventData = JSON.parse(e.data);



       if (e.origin.includes(popupOrigin)) {

          // Check for the message

          if  (eventData === 'variable') {

             // do whatever you need with the variable

          }

       }

   }



  // Listen for the message from the popup

  window.addEventListener('message', handleMessage);

 }

</script>
