First Public Working Draft: Payment Handler API

The Web Payments Working Group has published a First Public Working Draft of Payment Handler API. The Working Group has previously published Payment Request API, which provides a standard way to initiate payment requests from Web pages and applications. User agents implementing that API prompt the user to select a way to handle the payment request, after which the user agent returns a payment response to the originating site. The new Payment Handler API defines capabilities that enable Web applications to handle payment requests, helping to streamline payments on the Web.
