Here's how you would map your Amazon categories.
1. Login to Hyperspace
2. Go to your Account settings
3. Click the orange arrow to the right and select "Amazon Settings"
Scroll all the way down to "Match Amazon Categories to Lightspeed" then select set on the category you want to set.
When you select the category you need to set a popup will appear. In this popup you would need to select the first branch of the category tree , and narrow it all the way down till you can no longer and it says "No data found"
Congratulations. You have just set your first category in our Amazon Integration.
