Keycloak Authorization - Resources with path valiables

Securing applications
1

Hi There,

I am explorig Keycloak Authorization for fine grained auth in one of our projects.
I have been trying to achieve some thing like “/customers/{custId}/audit” or “/customers/{custId}/audit/{auditId}” while creating resource URIs but not able to do it.
Also, I am using below api for policy evaluation at gateway, it works for simple RBAC policies, is there a way to make it work for ABAC policies?
