As an affiliate in the Amazon Associates Program, you have a range of reports at your disposal.

These not only offer a real-time overview of the current status of any orders made via one of your Affiliate links, but also provide a detailed overview of your earnings.

Link Group / Clicks / Conversions / Number of items ordered / Items Shipped / Earnings

Also, which is very important for users using the PA API, you can see a table with information about the Link Type Performance.
What is this? It's a precise overview of the performance data from your used Affiliate links. Direct requests to the Amazon Product Advertising API (PA API) are also included.

Note that your account will lose access to Product Advertising API 5.0 if it has not generated referring sales for a consecutive 30-day period.
In order to maintain access to the PA API, the links sent to Amazon must not be direct links, so you can either use the "Add to cart" option from WZone or simply activate the 90 days cookie.

If you use direct links, the sales you will generate will not be taken into consideration as PA API Links, and you will be able to see them as "Product Links" in the Link Type Performance table.

Product ASIN / Item Link / Clicks / Conversions / Direct Ordered Items / Indirect Ordered Items / Ordered Items

Direct Ordered items = purchases made from your website for a precise product
Indirect Ordered Items = purchases made through the 90 days cookie
