name: Apple Push Notification Service (APNs)
description: The Apple Push Notification service (APNs) is the HTTP/2 + JSON push delivery surface for
  sending remote notifications, background updates, VoIP pushes, and Live Activity updates to iOS, iPadOS,
  watchOS, tvOS and macOS devices. Providers authenticate either with a token-based JWT (ES256) or with
  a per-app TLS client certificate, and POST a notification payload to /3/device/{deviceToken}. APNs is
  the transport behind every push notification on iOS.
