# 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 transactions
* `autopay` - sets up recurring subscriptions with a billing schedule
* `tokenization` - tokenizes payment method without charging customer

See [ExpressCheckout UI](/guides/pay-in-components-express-checkout#use-cases) 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](/guides/pay-in-components-express-checkout#use-cases) for more information about the `saveIfSuccess` field.
