If you connect your store, your store orders will be automatically synchronized to the Orders page. At this time, the order is in the pending state, and then you need to manually pay the basic cost and shipping fee to fulfill it
If you have not connected your store, you can click "Create an order" on the My Products page after designing the product to enter the order creation process, and then fill in the relevant information.
If you want to set up automatic payment fulfillment, you only need to set it on the Payment page.
