Becoming an Associate
Associates earn commissions by using their own websites to refer sales to Amazon.com. To get a commission, an Associate must have an Associate ID, also known as an Associate tag. The Associate ID is an automatically generated unique identifier that you will need to make requests through the Product Advertising API.
You must register for Amazon Associates before you register as a Product Advertising API developer. If you make a request with an invalid Associate ID, the Product Advertising API returns an error.
To become an associate
Using the following table, choose the Amazon Associates URL for your locale.
Follow the instructions to create an Amazon Associates account.
When you register as an Amazon Associate, an Associate ID is sent you in email. When you sign in to Amazon Associates for your locale, the home page displays a Signed in as YourAssociateID message.
One of the requirements for becoming an Associate is that you provide the URL of your site. If your site is not yet public but you want to test against the API, you must still provide a URL during registration.
Your Associate ID works only in the locale in which you register. If you want to be an Associate in more than one locale, you must register separately for each locale.
