## Interface EventListenerProvider

- All Superinterfaces:
    Provider
  All Known Subinterfaces:
    EventStoreProvider
  All Known Implementing Classes:
    EmailEventListenerProvider, JBossLoggingEventListenerProvider, JpaEventStoreProvider

      public interface EventListenerProvider
      extends Provider

  Author:
    Stian Thorgersen This interface provides a way to listen to events that happen during the keycloak run.

    There are two types of events:
    - Event - User events (fired when users do some action, like log in, register etc.)
    - Admin event - An administrator did some action like client created/updated etc.
    Implementors can leverage the fact that the `onEvent` and `onAdminEvent` are run within a running transaction. Hence, if the event processing uses JPA, it can insert event details into a table, and the whole transaction including the event is either committed or rolled back. However if transaction processing is not an option, e.g. in the case of log files, it is recommended to hook onto transaction after the commit is complete via the `KeycloakTransactionManager.enlistAfterCompletion(KeycloakTransaction)` method, so that the events are stacked in memory and only written to the file after the original transaction completes successfully.
