All event listeners will inherit from IEventListener<T> where T is a Zpider event.
This is the code behind the Trustpilot integration in Zpider. In this example we are listening for both the PageLoadEvent in order to inject a trustbox using the PageBuilderService and a PlaceOrderEvent to pass a copy of the order to Trustpilot so that they can send an invitation when the order is ready.
