Functional parameters provide data that is required by the ATG REST Web Services operation you are performing. For example, if you are setting a property value, the new value is a functional parameter of the operation.

You can include functional parameters either in the URL for the ATG REST Web Service or in the message body of a POST or PUT request.

The functional parameters you provide for an ATG REST Web Services operation depend on the nature of that operation. When invoking a method, you may supply arguments to it. When invoking a form handler, you will supply the form field values. When setting a repository item property value, you will supply the new value. The functional parameters for each operation are explained in the procedures for those operations.
