LineItem

The total amount of the line item given as a string representation float with decimal places representing the lowest denominations of the currency. This follows the W3 Payment Request API standard - https://www.w3.org/TR/payment-request/#dfn-valid-decimal-monetary-value

For example, a total of "10" is represented as "10.00" or "10" for currencies with fractional denominations (such as USD), while the total is represented as "10" in currencies without fractional denominations, such as JPY.

This is typically the cost of an item or service, or additional charge (e.g., taxes, shipping). Use "0" to indicate free or no cost ("0.00" is also valid for currencies with fractional denominations, such as USD), and negative values to indicate discounts, etc.

If the line item is a payment total, this is the total charge of the payment and should equal the sum of the line items.

An internal ID, such as a SKU, for the item.

URL for an image of the item.

This field does not apply to Apple Pay or Google Pay.

Description or purpose of the line item. This is typically the name of the item or service purchased. If the line item is a payment total, the label is instead the merchant name.

Indicates whether the value in the amount field represents an estimated or unknown cost.

Default: false

If the line item is a payment total and any other line item is pending, the total must also be pending.

Notes

• Apple Pay displays pending line items with an amount of "pending" instead of the amount value.
• Google Pay does not display pending line items.
