SuperDS FAQ

How does the Non-API lister keep my eBay account safe?

Unlike most tools that use the official eBay API (which has strict rate limits and can flag high-volume activity), SuperDS uses a proprietary browser automation method that mimics human seller behavior. This means your account isn't associated with the high-speed, bulk actions that often trigger eBay's restriction algorithms. It's a safer, more sustainable way to list products at scale without risking your account's health!

Do I need to buy UPC codes for my listings?

Absolutely not! SuperDS includes an Auto UPC Generator that automatically creates valid, GS1-compliant UPC codes for your products at no extra cost. This feature completely eliminates the need to purchase, manage, or worry about UPC codes yourself. It's one less expense and one less administrative task, allowing you to list products seamlessly and keep your focus on growing sales!

Which suppliers can I import products from?

SuperDS supports a vast and growing network of over 15 major suppliers and wholesalers! This includes giants like Amazon, AliExpress, Alibaba, CJDropshipping, Banggood, and many more. This diversity allows you to source a wide variety of products, compare prices, and find the best deals all from within the SuperDS platform, giving you incredible flexibility and sourcing power!

How does the Price & Stock Monitor work?

This powerful feature runs continuously in the background! It automatically tracks the price and inventory availability of your sourced products on the supplier's website. If a price changes or an item goes out of stock, SuperDS alerts you immediately within your dashboard. You can then review the changes and, with a single click, update all your affected eBay listings to stay competitive and avoid selling unavailable items!
