The way impact.com tracks attribution for the Amazon Seller program differs from the tracking methods typically used in our other programs. With Seller, we rely on the Amazon Attribution API to handle attribution tracking, and this comes with certain characteristics.
Amazon’s attribution tracking doesn’t support cross-country tracking, meaning that Amazon will only track traffic to your Amazon site and attribute it to the relevant partner when your site and the partner’s audience are in the same country/region.

With Seller, neither you nor your partners can pass extra data with a conversion by adding parameters such as subids and sharedids to tracking links.

Additionally, if your partners participate in Amazon Associates , they cannot append impact.com and Amazon Associate tracking links to each other to earn multiple commissions on the same conversion.
For product returns, you don’t need to submit a data file to impact.com to process action reversals or modifications. Amazon handles returns as usual, and your conversion data will update on impact.com within a 28-day rolling window.

impact.com cannot give you insight into the user’s click path or journey leading up to a purchase. With the Seller program, you won’t have visibility into these details in the same way you would, for instance, in your Performance program with the Top Paths report.
