Order Item Parameters: Introduction

This section describes the order item parameters in your shopping cart. An order item holds information about one item to be purchased. Order item parameters describe the characteristics of a single order item.

All order item parameters fall into one of these categories:

• Required, which you must set.

• Optional, which you may or may not set, but might provide additional useful information to Transact.

Names are case-sensitive. Values, including numeric quantities, are strings for both input and output.

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

To set a parameter, call CART.SETITEMPARAMETERS.

To get the value of a single parameter, call CART.GETITEMPARAMETER. To get the values of a list of parameters, call CART.GETITEMPARAMETERS.

For more information about shopping cart parameters, see Chapter 16, "Sites Cart Parameters."

We organized the parameters by function:

• General Parameters

• Product Description Parameters

• Delivery Parameters

• Cost and Payment Parameters

• Subscription Parameters

• Tax Parameters

• Custom Field Parameters

Each table contains the following four columns:

Name - Name of the parameter.

Description - A brief description of the parameter. More detailed explanations of the parameters follow each table.

Value Range - Range of values for the parameter.

Constraints - One of the following:

• Required: You must specify a value for this parameter.

• Required if: You must specify a value if the stated condition is true.

• OK if: You may specify a value only if the stated condition is true.

• Prohibited if: You cannot specify a value if the other specified parameter has the specified value.

• Mutually Exclusive: You cannot specify a value if the other specified parameter has any value.

• Default: The default value if you do not specify a value.
