Hello Miguel, There is no default mechanism to notify clients, so you'll have to implement it yourself. That shouldn't be that hard, especially given that it's a perfect case for a message-driven solution. I'd suggest that you use Keycloak's builtin ActiveMQ Artemis message broker [1], which supports persistence and message redelivery. Write your EventListenerProvider, listen for AdminEvents, publish them to MQ and subscribe your clients to it. If your clients are also Java-based, JMS should be your choice. Otherwise, you should be using AMQP directly. Good luck, Dmitry Telegin CTO, Acutus s.r.o.
