On successful client authorization, the XACML-JSON PDP API invokes the Policy Decision Service with the batch decision requests converted from the XACML-JSON request.

When writing policy for the XACML-JSON PDP API endpoint, you should note the mapping between the XACML-JSON schema and the PingAuthorize Server decision request. For more information, see Requests and Responses.

After the Policy Decision Service determines a decision response, it hands the response back to the XACML-JSON PDP API to provide to the client.
