Buy Now Checkout
You can let Amazon Pay handle the full checkout flow for one-time transactions and reduce buyer redirection via Buy Now. Unlike the one-time integration, the buyer will not need to return to your site to review their order before completing checkout. Everything is handled and provided on the Amazon Pay Buy Now hosted checkout page.
During a checkout, Amazon Pay will invoke event handlers in your shop to exchange checkout-related information. This includes the address selected by the customer on the Amazon hosted checkout page for physical goods, coupon codes provided by the customer, if applicable. In return, your shop will respond to those operations with cartDetails. These include e.g. available delivery options, optional line item information to display to the buyer and order amounts.
