It is used to convert JSON data coming from or returning to the client into a different format.
If this policy is used in the request line (Client → API Proxy → API), the message body from the client is transformed and transmitted to the Backend API.
If it is used in the response line (API → API Proxy → Client), the result is transmitted to the client by applying transformation on the message body returned from the Backend API.
