Order system overview

Describes the order management APIs in Optimizely Customized Commerce and provides an overview of components used when working with orders.

Order APIs

You should avoid casting back and forth between concrete Order classes such as OrderGroup and OrderForm, and abstraction interfaces such as IOrderGroup and IOrderForm. For example, you should use only one API from the time you load a cart or purchase order until you save it. While this is not always possible, doing it whenever possible helps avoid hidden problems when casting.
