wikipedia the free encyclopedia notification service created by apple apple push notification service logo developer s apple target platform s iphone os 3 0 and newer os x lion and newer safari 7 0 and newer status active license closed source website https developer apple com notifications apple push notification service apns previously known as apple push service aps is a platform notification service created by apple that enables third party application developers to send notification data to applications installed on apple devices the notification information sent can include badges sounds newsstand updates or custom text alerts it was first launched with iphone os 3 on june 17 2009 apns support for local applications was later added to the mac os x api beginning with the release of mac os x 10 7 lion support for website notifications was later added with the release of mac os x 10 9 mavericks history edit apple announced the service on june 9 2008 with an original stated release for that september however as stated by scott forstall at the ios 3 0 preview event on march 17 2009 the rollout was delayed after a decision to restructure the apns for scalability purposes due to the allegedly overwhelming response to the announcement of the apns at both events forstall stated that push notifications better conserve battery than background processes which are used in pull technology for receiving notifications 1 apns was first launched together with ios 3 0 on june 17 2009 2 the release of ios 5 0 included a notification center adding support for receiving and reading local notifications in a single place 3 apns was also added as an api to mac os x 10 7 lion so that developers could begin updating their third party applications and start utilizing the service 4 5 support was later improved in os x 10 8 mountain lion with the introduction of a notification center as with ios 5 0 the improvement allowed users to manage and read their received notifications in a single location 6 7 the release of os x 10 9 mavericks included safari 7 0 which added support for accepting and receiving apns notifications from websites that the user granted permission to 8 9 in december 2023 concerns arose regarding a potential privacy and surveillance loopholes involving push notifications delivered through apns us senator ron wyden revealed through a letter to the department of justice that both the us government and foreign law enforcement could demand user data from apple related to push notifications 10 technical details edit in 2014 the maximum size allowed for a notification payload sent through the binary interface was increased from 256 bytes to 2 kilobytes in december 2015 a new http 2 provider api was released by apple effectively replacing the now legacy binary interface the maximum notification payload size allowed using the http 2 api is 4 kilobytes 11 apple shut down the legacy binary api at the end of march 2021 12 the http 2 provider for apns uses tcp port 443 as the main port of communication but developers are also allowed to use tcp port 2197 if outbound access to port 443 is blocked by firewalls 13 in addition if an ios ipados app has the background app refresh permission it is allowed to access app developer s server to get updated data in background 14 see also edit imessage facetime firebase
