Notification means the act of conveying a message. A push notification is an automated message that pops up when an alert is sent by an app. This message is sent by the server of the app and works even when the app is not open. Now, APNs is slightly different.<\/p>\n

What is APNs?<\/h2>\n

Apple’s Push Notification Service<\/a> is a cloud platform that enables third-party app developers to send\/push alerts to their apps running on Apple devices. APNs give app developers the ability to send unique alert messages, play a sound, provide actions that users can do without opening the app, and more.<\/p>\n

After you’ve set up push notifications on your providers and in your app, you’ll be able to send notification requests. Each targeted device receives relevant notification payloads through APNs. When a notification is received, the system sends the payload to the relevant app on the device and controls the user’s interactions.<\/p>\n

The app must be correctly set up and registered with the Apple Push Notification Service in order to receive APNs push alerts. The service uses an application programming interface (API) that is built into all iOS and Mac OS X devices to provide alerts. APNs were initially introduced by Apple with iOS 3 for the iPhone in June 2009. Users may manage and see notifications in one location using the Notification Center, which was initially introduced in 2012 with the introduction of iOS 5.

\r\n \t\t\t\t\tIncluding a custom action with the notification, provides the user a quick interaction with the app. For example the option to ‘reply’ for a messaging app notification, \u2018Browse more products\u2019 for a shopping app etc. \t\t\t\t<\/p>\r\n \t\t\t \t\t\t\r\n \t\t<\/div>\r\n \t\t<\/p>\n

APNs X UEM<\/h2>\n

APNs give UEMs a means to communicate with linked Apple devices and transmit messages\/notifications. The APNs server functions as a gateway between a UEM server and its linked Apple endpoints, allowing communication between the two. The message is forwarded to the APNs server, which reroutes it to the appropriate device (or a group of devices).
\nFor eg: You have an enterprise app that sends you information about an office update, the app uses APIs to send a text alert to an iPhone. When your app is first launched on a user’s device, the system automatically establishes an IP link with your app and Apple Push Notification Service.<\/p>\n
