Changes for May 11, 2026
New mode field for ExpressCheckout UI
We added the mode field to the ExpressCheckout UI configuration.
The mode field determines the behavior of the ExpressCheckout UI component.
This field accepts three values:
one_time- process one-time transactionsautopay- sets up recurring subscriptions with a billing scheduletokenization- tokenizes payment method without charging customer
See ExpressCheckout UI for more information about the use cases supported by the ExpressCheckout UI component.
New saveIfSuccess field for ExpressCheckout UI
We added the saveIfSuccess field to the ExpressCheckout UI configuration.
The saveIfSuccess field enables the ExpressCheckout UI component to process a one-time transaction and tokenize the payment method for future use.
When saveIfSuccess is set to true, the ExpressCheckout UI component saves the payment method if the transaction is successful.
This field only works when the mode field is set to one_time.
See ExpressCheckout UI for more information about the saveIfSuccess field.
