New networkTransactionIdentifier value in orders API payment object

On 2026-04-01, the OrderPayment object in the orders API will include a new networkTransactionIdentifier value. This value contains a unique identifier provided by a card network (such as Visa, Mastercard, or American Express) when a credit card payment is authorized. You can use this identifier to identify guests using a specific card network across different transactions.

For more information about the networkTransactionIdentifier value, see the Payment object reference documentation.
