Manage shipment fields
WPCargo has predefined shipment detail fields upon installation. Using Custom Field Add-on, you are able to add, update or remove those fields. It also allows you to create your custom section with the custom fields you wanted to add.
WPCargo Custom Field Add-ons provides meta tags of the shipment data you want to include in your label information. All of the fields you have added in your Custom Field add-on will generate meta tags which you can add to their respective label sections or customize the order of the information displayed in CF Print Label settings.
