PayPal Review Page Order Details
NOTE: PayPal Review Page order details are available with API version 53.0 or later. The
DoExpressCheckoutPayment request includes the same order details as
SetExpressCheckout. It is strongly recommended that you submit the same
parameters in both API calls.
When a buyer logs into PayPal to check out, you can present the buyer with detailed
information about each item in the shopping cart (see PayPal Review page with order details):
(1) – Item name. The item name can identify this item to distinguish it from other line items in
the order.
(2) – Item number. Each item can be further identified by an item number. If the item is an
eBay auction item, it is recommended that you provide the eBay item number in this field.
(3) – Item description. This field identifies which of several items the buyer is purchasing. For
example, you may be offering an item in different sizes. Knowing the size helps the buyer
decide whether the one they selected was appropriate. If the item is an eBay auction item, it is
recommended that you provide the phrase “eBay item” in this field.
(4) – Item unit price. This field specifies exactly how much one unit of the item costs. It can be
a positive or negative value but not zero.
(5) – Item unit quantity. This field identifies the number of units the buyer is ordering.
