[keycloak-user] Extend keycloak notifications

Hi, I'm considering to create a new application and for sure I'll use keycloak as user backend. It's really cool stuff what you guys created. I thought about various solutions for notifications of my application and was wondering if you guys already thought about to extend your e-mail notification to a more general and flexible system. So that not only keycloak e-mails will be sent over keycloak but also other applications e-mails and even more notifications can be send over keycloak (I'm thinking here of SMS, etc.). Therefore applications would need to upload any kind of templates to keycloak and somehow be able to manage them. There are 2 reasons for such a step. First of all keycloak already provides such basic functionality to sent notifications and so extending it could be done with lower overhead. Second, keycloak already owns the recipient data, if applications manage users over keycloak. As additional feature of course a proper monitoring should be placed in such a feature, since notifications are really vital to modern applications. We would be able to provide programming resources for such a feature but of course working together, specially for the design phase, with you guys. The alternative would be to provide a different notification system and forward keycloak e-mails to that service (actually the event to sent a notification). Don't know if this actually is the way to go ... My motivation for such a feature is, that a single application should be responsible for sending notifications of any kind and not be widespread over various applications. Any ideas welcome ;) Eventually I overlooked something in my design ... Thx in advance for all your thoughts & all the best /david
