+short_description: Allows administration of Keycloak client custom Javascript policies using Keycloak API
+
+version_added: "3.0.0"
+
+description:
+  - This module allows the administration of Keycloak client custom Javascript using the Keycloak REST API. Custom Javascript
+    policies are only available if a client has Authorization enabled and if they have been deployed to the Keycloak server
+    as JAR files.
+  - This module requires access to the REST API using OpenID Connect; the user connecting and the realm being used must have
+    the requisite access rights. In a default Keycloak installation, admin-cli and an admin user would work, as would a separate
+    realm definition with the scope tailored to your needs and a user having the expected roles.
+  - The names of module options are snake_cased versions of the camelCase options used by Keycloak. The Authorization Services
+    paths and payloads have not officially been documented by the Keycloak project.
+    U(https://www.puppeteers.net/blog/keycloak-authorization-services-rest-api-paths-and-payload/).
