Line Items

With the checkout API, a merchant can send product information to their customers on the checkout page. If the products are declared as line items, they will be shown under the order amount in the show details section.

• Line Item – Every product on the order is referenced by a record that includes a product name, quantity, and price

The sum of total amounts declared per product is equal to the order amount.

Availability

This feature is available on all merchant accounts.

The line item array is not mandatory when the create checkout is used; however, certain APMs require the usage of line items to validate the order content.
