Amazon Payments is the payment processor Amazon DevPay uses to process your customers' payments and disburse money to you. For more information about Amazon Payments, go to http://payments.amazon.com. The following sections give you an overview of Amazon Payments and how it's related to Amazon DevPay.
To use Amazon DevPay, you need an Amazon Payments account (specifically, an Amazon Payments Business Account). The money you make from your DevPay customers is deposited into this account. There are a variety of ways to use Amazon Payments, and they're covered on the Amazon Payments web site (http://payments.amazon.com). However, for the purposes of DevPay, you primarily just need to know that your customers' payments go into your Amazon Payments account. For information about how you get this account and access it, see Your Amazon Payments Account.
Amazon Payments processes your DevPay customers' payments. The only Amazon branding that your customers see in relation to your DevPay product is for Amazon Payments.
The one exception to this is for customers who purchase Amazon EC2 AMI products; they also see AWS branding because they must be signed up for an Amazon EC2 account.
Your site should make it clear that Amazon Payments is handling the billing for your product. Your customers will see the Amazon Payments logo on the pages showing the usage and billing data for your product. We require you to include the Amazon Payments trademark or logo on your site to help make your customers' experience consistent between your site and our site. The trademark, logo, and guidelines for using them with Amazon DevPay are available in the co-marketing area of the Developer Connection web site.
