Push Notifications

Informacija Atsiprašome, šis skyrius galimas tik anglų kalba.

This chapter describes methods to be used to get push notifications to the phone. Push notifications are available only for clients with type app_client, that is, applications in phones.

Following scheme is used to provide push notifications for the user:

  • Client subscribes to events, providing event names and filters.
  • Push notification is sent after each subscribed event with basic event information.
  • Client gets all pending events from API with full information.
  • Client unsubscribes from events to stop push notifications. Notifications also stops after access token is invalidated.

Events and their subscriptions are always bound to access token - if new access token is issued, client must re-subscribe to the events. All methods must be accessed with access token to work.

This method is used to subscribe to events and send push notifications for each of them.
