Hi there ,
I think you need to understand the concept of API from the very begining, below somthing helpful
Sign up as an Amazon associate. You have to submit an enrollment form online, providing information about the website on which you want to advertise Amazon products. If Amazon accepts your application, it will create a Web services account that enables you to use the Product Advertising API, as well as Amazon’s Data Feed and Product Advertising Content.
Contact the Product Advertising API to obtain advertising material for your site. Amazon provides you with an account identifier – a public/private key pair for encrypting your communications with Amazon – that you must use to connect your site with the API.
Choose the kind of links you want your site to host as an associate. Product links allow you to display a particular item on your site. Omakase links select products Amazon considers appropriate for your site, without any effort on your part. Product Previews provide added data, such as user reviews, to site visitors before they click through to Amazon. With Recommended Links , you describe the general range of products you want to market, and Amazon chooses links within that range.
Resubmit your Product Advertising requests if Amazon gives you an error message. Errors come in three categories: You’ve entered a technically incorrect request and must enter a correct version; your request was rejected for another reason; or the problem lies with Amazon’s inability to process the request. A 503 error in the latter category, for example, means you need to slow your request rate to one per second.
