The API integration is the most basic and is a standard ecommerce protocol where the data only goes one-way, from you to us. We cannot make actions from our end so you maintain all of the control.   The API integration with empact works only based on the fact that your online shop notifies empact on specific events such as sales, returns, new products added, so that eventually empact can actually take responsibility over your full eCommerce activity in Europe and make the required reporting, filing and paying to authorities on your behalf.   Empact cannot access any additional data existing in your shop, and the control is fully managed on your end.
