First, you need to create a Facebook Business Page and connect it with your eCommerce website. The fastest way to get your products onto Facebook is to use 3dcart to export qualifying products onto your Facebook Shop tab. This way, you don't have to add products manually to Facebook; it will simply pull your product names, images, pricing, and other details from your 3dcart products. You'll also be able to manage your orders through your 3dcart dashboard and your inventory counts will remain consistent through synchronization.
