Product Advertising API
Developer Guide (API Version 2013-08-01)

AssociateTag Parameter

An AssociateTag is an alphanumeric token distributed by Amazon that uniquely identifies an Associate. Amazon uses this ID to credit an Associate for a sale. The AssociateTag parameter becomes part of the PurchaseURL, which is the URL used to purchase the items in a remote shopping cart.


You must include an AssociateTag value in all requests to the Product Advertising API. If a request does not have an AssociateTag value, Product Advertising API returns an error.

For information about how to get an AssociateTag, see Sign up as an Amazon Associate.
