The Amazon Pay button appears in the shipping step of checkout, the cart page, the mini-cart, and, depending on configuration, the Product Detail Page (PDP). Customizations may be required in themes not based in Luma or Blank, to ensure the Amazon Pay button appears where expected.
Amazon Pay can be configured to capture funds upon order placement or upon order shipment by simply generating an invoice.
