VitalBuddies review for Shopify Marketplace Connect

I believe Marketplace Connect is mainly suited for simple products. We operate in a niche market for pet supplements, and the app fails to map this category correctly to the Amazon API. Some fields in the app allow for free-form text, whereas the official Amazon API requires a dropdown menu with fixed variables. This causes a constant error from Amazon whenever you fill in those fields, making it impossible to link products and list them on the platform. The app/API integration is incomplete and subpar. Not worth more than 1 star.
