## What it is
A Java client library for the Apple Push Notification service (APNs) that sends push notifications to iOS/macOS devices. It is now defunct because Apple shut down the legacy binary protocol it relies on in March 2021.

## Use cases
- send push notifications to ios devices from java
- java apns client library
- push notifications with apple certificates
- send newsstand and mdm notifications
- query apple feedback service for invalid tokens

## When to choose
- maintaining a legacy codebase already built on java-apns
- studying how apns binary-protocol clients were implemented

## When to avoid
- any new project - the library no longer works since Apple disabled the legacy binary protocol
- you need a working APNs client - use Pushy instead, which supports the HTTP/2 protocol

## Facets
- artifact type: library
- maturity: abandoned
- function: http-client, serialization, json
- domain: mobile-development, apis, developer-tools
- platform: jvm, cross-platform
- tags: apns, push-notifications, ios, deprecated, apple
