I know keycloak has exposed below api,
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-services</artifactId>
<version>2.0.0.Final</version>
</dependency>
With complete documentation here. I cannot find the required api here to fetch all users with specific role mapped to them.
Problem Statement - I need to pick all users from keycloak server who have a specific role. I need to send email to all users with role mapped to them.
There is an outstanding feature request asking for this function via the API.
In the meantime if your requirement is once-off you could obtain the user names (or email addresses) by interrogating the database joining KEYCLOAK_ROLE to USER_ROLE_MAPPING to USER_ENTITY
Something like:
SELECT username
FROM keycloak_role kr
JOIN user_role_mapping rm ON kr.id = rm.role_id
JOIN user_entity ue ON rm.user_id = ue.id
WHERE kr.name = 'your_role_name';
