A push request is a row of values in a result set that a Notifier checks to determine if push notifications need to be sent to a device. A Notifier places the push request inside a push notification then sends the push notification. In a typical server-initiated synchronization set up, a push request contains message content and target device information. Before a push notification can be sent, you need to configure a Notifier event so that the Notifier can detect the push request.
