After installing and activating the plugin, a new shipping method ‘FedEx’ is added to WooCommerce Shipping settings. Now you can configure this FedEx shipping method as per your requirement. You can navigate to the setting in two ways.
1) From Installed Plugin Settings
(Plugin > Installed Plugin > Woocommerce Shipping Pro-FedEx > Settings)
2) From Woocommerce Settings
(Woocommerce > Settings > Shipping > FedEx)
