Best Practice With Using REST Service POST

Hello,  I am wondering if there is any recommendations with using a REST service call, POST. I will be using it to share or update information between apps, and was wondering what is the required workflow for mendix to “package” the data as needed? Such as creating a JSON file if needed and how to configure mapping etc.  If there is any additional reading resources that would be very helpful.
