Sending true wakes your app from background to run custom native code (Apple interprets this as content-available=1). Note: Not applicable if the app is in the "force-quit" state (i.e app was swiped away). Omit the contents field to prevent displaying a visible notification.

Sending true allows you to change the notification content in your app before it is displayed. Triggers didReceive(_:withContentHandler:) on your UNNotificationServiceExtension.

Due to the complexity of supporting different types of user targeting, this field uses JSON to describe targeting filters.

{"field": "amount_spent", "relation": ">","value": "0"}
]
