Getting Authorization

Before you can issue an Amazon FPS request that charges a buyer for an item, you must get the buyer's authorization. The authorization process uses the Amazon Co-Branded service, which has a different API from the Amazon FPS web service. Some of the values returned by the Co-Branded web service, however, are required in Amazon FPS requests. When the buyer authorizes a purchase, the Amazon Co-Branded service creates a payment token, which enables the exchange of money from buyer to seller.

This section describes how to use the Co-Branded API and payment tokens. The remainder of this guide describes how to use the Amazon FPS API.
