In the menu on the left, click on Your Products and then click on Create new product. You will be guided through a flow that will provide us with all the information we need to configure a new product. As soon as you've submitted your request for a new product, we will review it and inform you whether it got accepted or declined. Once it gets accepted, we will give it a polish and automatically translate it to 10 languages. As soon as this is done, we'll let you know that your product is ready for the final touch where you add availability!
