What is Amazon MWS?
What you should know abou the Amazon MWS Reports API Section
Report Type enumeration
This is where the docs lead and at the end of it there are two Business Reports available to call over API:
Manage Quotes Report
Referral Fee Discounts Report
The real question is how do companies like Sellerly, Splitly, or Listing Dojo find this information (Sessions, Page Views, Buy Box Percentage, etc. per ASIN or SKU) if it is not directly available? Maybe they are not using these metrics, and instead rely solely on conversions/sales only?
Currently I am manually downloading the daily reports, appending product information, and then loading that into a database for in-house a/b testing
