Cart Parameters

Your shopping cart interface includes two types of parameters:

• Order parameters describe the entire order. For example, the order parameter named totalSalesAmount holds the total cost of the entire order.

• Order item parameters describe a single order item. For example, the order item parameter UniqueID holds the SKU of the item being sold.

This chapter details all shopping cart order parameters. For information about order item parameters, see "Sites Order Item Parameters"

The terms registered buyer and walk-in buyer appear throughout this chapter. Registered buyers have already set up accounts that identify their names, billing addresses, and payment brands. Registered buyers identify themselves to Sites, which retrieves their account information, and then passes it on via the Commerce Connector to Transact for processing. By contrast, walk-in buyers do not have accounts set up with Transact. Therefore, walk-in buyers must provide all name, billing address, and payment brand information.

Note The Transact Order Entry API (OEAPI) documentation uses the term attribute when referring to a shopping cart argument. This document, however, uses the term parameter to avoid confusion with an attribute, which is an asset that describes other assets in the catalog.

To set a parameter, call CART.SETPARAMETERS .

To get the value of a single parameter, call CART.GETPARAMETER . To get the values of a list of parameters, call CART.GETPARAMETERS .

For more information about shopping cart tags, see Cart Tags .

Note If you call CART.SETPARAMETERS to set the value of an informational parameter, the Transact system that processes cart transactions may erase that value the next time you call either CART.GETPARAMETER or CART.GETPARAMETERS .
