Use WordPress eShop FedEx Shipping Rates Plugin to replace eShop’s default shipping methods with live calls to Federal Express.
eShop Shipping Extension framework overrides eShop’s default shipping methods, interacting directly with Fedex and other systems for real-time shipping rates and services.
Other services such as DHL will be made available soon. See the bottom of this page for UPS, USPS, and Correios
Please note that if you’re using WooCommerce, turn away – this is NOT FOR YOU! This works with eShop for WordPress only.
