Wait For Clickthrough
This is a simple Activity Element with a wait for event action. Here, we're waiting for the event "Customer Updated". This occurs when an update to a customer in the CRM has occurred. This corresponds to the CRM update that we do in the offer handler php page.
If the "Customer Updated" event does not occur within the allotted time, this element will throw a timeout exception. Our next element will handle this exception and send another email to the customer.
