Amazon FPS Marketplace Quick Start, with its unique three-party transaction model, allows you to build marketplace applications in which you are neither the buyer nor the seller. For example, you could build a “New Artist MP3 Discovery” web site where music fans can purchase music and pay the artists directly. You, as the developer of the web site, can take a portion from each transaction for facilitating the transaction.
Amazon FPS Marketplace functionality includes one-time payments, reserving funds on the sender’s credit card, settling payments at a later time, refunding and canceling transactions. This functionality is based on the years of experience Amazon has in handling transactions, including fraud detection, secure transfer of funds, and continuous uptime of web services.
For more advanced or different functionality, such as account management, refer to the other Amazon FPS documentation.
