Customers on your store can now choose to pay with their credit cards and bank accounts stored in their Amazon account. Their Amazon billing information is never exposed to the merchant. The customer can quickly login to their Amazon account, select their payment method and pay for their online order. They are then redirected back to your store to view their receipt, download their products, watch their videos, etc.
If you are using a payment provider such as PayPal Pro or Authorize.net and want to accept Amazon payments alongside your credit card payment selections, go to “Store Setup > Order Checkout Setup > Checkout Billing Options Configuration” and turn on the Amazon payments option and enter your Amazon credentials.
If you are using PayPal Standard to process your store payments and you want to also accept Amazon OR you want to only accept Amazon on your store, go to: “Store Setup > Order Checkout Setup > PayPal Standard | Amazon Payments” and turn on the Amazon payments option(s) and enter your Amazon credentials.
