Question: Is it against the amazon ToS to allow use of third party affiliate ids? For example: Would it be legitimate to create a program that uses the amazon api to display products and then allow third parties to send traffic to that site using their affiliate id, then put that id in all the links to amazon? So, say Amazon sells widgets, and you create a little api website that displays widgets for sale on amazon. WidgetBlogger links to you like this: http://www.example.com/product.php?affiliate_id=widgetblogger-20 The point is that it would work for whoever links to you, and when someone doesn't link to you using an affiliate id, it uses a default one. Is this against amazon's terms of service? Anyone know?
