I've been using your tool for a while for consolidating my Adwords, Facebook, and Google Analytics activity automatically – it's extremely useful. I'm a big fan.
I'm writing to get in touch about if you have any suggestions on how to do similar things with Amazon's Vendor Central and Seller Central reporting tools. This is currently a very time intensive data entry job for our team, and I'm sure there's a better way to do it.
Thanks for your message, and the good feedback!
At the moment our devs are building a connector for Amazon Marketing Services, but I'm not sure you can get the data you'd need from that API. It's a different service, right?
Anyway, it will take a couple months for us to finish the Amazon Marketing Services connector. We will announce it to our users once it is available for testing.
