Publish rest service | Inputs & Best practice

Hi All, Need input for publishing as rest service. By right-clicking the entity and choosing the option expose as rest service I have created all the operations (GET, POST PATCH...)and noticed outputs are generated in XML. I have gone through the document and using export mapping outputs are generated in JSON for the GET method but for the POST method, I didn't find any documentation. Below is my requirement, .I need to create a record using the POST method and the request should be in JSON..please share the steps on how we can do that and what is the best practice
