Manage shipping zones, shipping methods, and shipping carrier connections.
The Shipping Zone object and endpoints manage shipping zones within countries.
The Shipping Methods object and endpoints manage shipping rules within Shipping Zones. These rules determine the shipping rates displayed at checkout, and related parts of the control panel, such as the shipping of manual orders.
Carrier connections refer to specific settings required to connect to a specific shipping carrier. Each carrier requires your app to supply a unique set of properties/fields to establish a connection with that carrier.
