## New `invoiceData` object for ExpressCheckout UI

We added the `invoiceData` object to the ExpressCheckout UI configuration.
The `invoiceData` object allows you to create an invoice for a transaction when using the ExpressCheckout UI component.
The `invoiceData` supports the `one_time` and `autopay` modes of the ExpressCheckout UI component.
See [ExpressCheckout UI](/guides/pay-in-components-express-checkout#configuration-reference) for more information about the `invoiceData` object.
