This article explains how to use the 'webinar started' event to run custom code as soon as your webinar begins.
You will need:



<script>
document.addEventListener('start_webinar', function () {
// insert your code here
console.log('the webinar started')
})
</script>
Click Save (4).




After confirming the trigger works, return to the editor and click Save (5) to save the changes. Once the changes are saved, the old version of the page cannot be restored.
