You can change product information except the SKU. We strongly recommend that you do not change product attributes. When your customers place an order for the product you changed, the product information will not be synchronized correctly to JetPrint because we will not be able to receive the order or produce the wrong order.
⚠️Note
You cannot change a single attribute to multiple attributes or vice versa. For example, if a product has only size as a product attribute, you cannot add color and size attributes to it.
