摘要

Disclosed is an approach for coordinating via two browser APIs with a payment service. The method includes receiving input from a user indicating a desire to purchase a product from a merchant site, and receiving, based on the input, at a browser and via a first API between the browser and the merchant site, a payment request from the merchant site for payment data. In response to the payment request, the method includes communicating, from the browser and via a second API between the browser and the payment service, a payment request event to the payment service, wherein the payment service can process a payment for the product. The method includes receiving, at the browser and from the payment service and via the second API, a confirmation of the payment and communicating, from the browser and via the first API to the merchant site, the confirmation.
