If you are still interested, we are exploring an integration with Amazon MWS which will allow you to tap Amazon ECommerce data using Tableau.
For anyone looking for Amazon MWS data we are asking they complete a short survey so we can gauge interest within the community for this type of data.
More details here: Amazon Marketplace Data Integration.
If you have any questions, please do not hesitate to reach out. Appreciate your interest!
We use vendoranalytics.io for our reports outside of ARAP. We just have them insert the data into a database that we connect to on Tableau and PowerBI. Works good!
