We are using wso2 identity server as an IAM solution(for creating roles and users and tenants). We are now implementing the architecture using wso2 ESB (in wso2 integration studio). So is there a way where we can call the wso2 IS(Identity Server) API's from ESB? Also, we were using script mediator in wso2 esb. Is there a way to generate authentication string here from the req body sent to the api being called.

I want to create this json using script mediator. is it possible because it is giving error? json:

            {
                "schemas": [],
                "userName": requestbody.userName,
                "password": requestbody.password,
                "emails":
                    [

                        {
                            "primary": true,
                            "value": requestbody.userName
                        }
                    ],
                "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User":
                {
                    "verifyEmail": true,
                    "oneTimePassword": requestbody.password
                }
            }

I have username and password coming in the body. I have to create rest of the fields using these two. Is it possible in script mediator? I am trying to hit this endpoint from ESB '/scim2/Users', which is a wso2 identity server api and needs data in the above described format itself. Please suggest a solution to implement this in wso2 ESB .
