Features
The Interstitial displays a creative on a blank screen for a few seconds before the actual content page is displayed.
Event listening
The Interstitial supports the adClosed event. You can listen to this event to control the functioning of your site. adClosed triggers when the close button is pressed or the ad is closed automatically. The event contains the parameter formatId to get information on which formatId (on the page) fired the event:
window.addEventListener('adClosed', function (e) {
console.log(e.formatId);
});
