            message: "Technical Error",
            origin_system: "Appian",
            backend_system: "",
            backend_code: "API-1002",
            backend_message: "There was an error starting the process"

        }

In above mentioned code I have manipulated the gender before calling the process model this way you can manipulate any tag which is coming in the WEB APi. Hope this helps you
