[keycloak-user] Entitlement request with additional parameters

Hi guys, I use the entitlement API to check access control on my resources. Here I check if a user can update a sensor: curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $TOKEN" -d '{ "permissions" : [ { "resource_set_name" : "Sensors", "scopes" : [ "sensors:update" ] } ] }' "http://localhost:8080/auth/realms/waziup/authz/entitlement/waziup" But I would like to make complex policies that check additional parameters, such as sensor status etc. How can I pass along the additional parameters to the request, and use them in my policies? I use javascript policies mainly. Thanks Corentin
