Amazon names shipping options generically, like Standard, Expedited, and Overnight. On your Amazon Seller Central account, you can set which options you will be offering your customers. As the orders import to SellerCloud they will have the shipping option selected by the customer.
However, you can map those generic options to specific services in order to streamline shipping processes. For example, you can map Standard to USPS Priority. Doing that will enable the order to export to ShipBridge with a pre-determined shipping method.
Navigate Company Settings > Amazon Settings > Shipping Method Mapping.
On this page you can map Amazon domestic and international orders to a pre-determined shipping method.
