Introduction to Amazon Simple Pay

Amazon Simple Pay is a set of basic payment-only products. Using online Amazon Simple Pay forms you can create fully-functional payment buttons, which you then add to your web page. These buttons allow your customers to use their Amazon.com accounts as a payment method for purchasing products and services from you. When customers click one of your Amazon Simple Pay buttons, they begin making a secure payment.

The Amazon Simple Pay Getting Started Guide details the processes and procedures involved to make use of Amazon Simple Pay's standard features without needing to write any code. In contrast, the Amazon Simple Pay Advanced User Guide concentrates on the advanced features available to you when you decide that your application calls for custom code. If you don't need to write code, but do want to make use of the basic features of Amazon Simple Pay, you should refer to the Amazon Simple Pay Getting Started Guide.

If you decide that it is necessary to change your access keys, the security credentials page (available from your account page at the Amazon Web Services web site at http://aws.amazon.com) enables you to create a second set, and allows you to activate and deactivate the sets independently, as shown in the figure.

With both sets active, you can propagate the new set to your applications over time, maintaining the high security that signing provides. Since both sets are valid, you don't have to take your entire application down to incorporate the new keys. When the distribution is complete you can deactivate the old set.

	Note
	You can have two sets of keys only. Both, one, or neither of them can be active.
