X-Cart’s Amazon Pay add-on provides integration with Amazon Pay. This payment service enables buyers to pay on your online store using the payment and shipping information already stored in their existing Amazon accounts. The interaction of buyers with Amazon Pay occurs in embedded widgets to complete the checkout process without ever leaving your website. In addition, Amazon Pay offers a seamless and hassle-free mobile payment experience across devices including Kindle, iOS, and Android.
Ensure you configured the store to use HTTPS in both the storefront and Admin area. Amazon Pay add-on requires it for proper functioning.
