Commerce FedEx provides direct FedEx integration with your Drupal Commerce 2.x e-commerce site on Drupal 8.
Supporting all FedEx shipping services and an increasing number of FedEx's special services, such as Hazardous Materials and Dry Ice, Commerce FedEx is designed to be your one-stop solution for all of your FedEx shipping requirements.
Until Commerce FedEx is enters the Beta phase, there will not be a guaranteed upgrade path between versions. We are doing our best to minimize disruption (we're using it in production already!), but pay close attention during upgrades as there may be cases where you will have to reinstall the module.
Please report bugs in the [issue queue] (https://www.drupal.org/project/issues/commerce_fedex?version=8.x).
Use Composer to get Commerce FedEx and all of its dependencies installed on your Drupal 8 site:
composer require drupal/commerce_fedex
Then simply enable the "FedEx (Commerce Shipping)" module and visit
Commerce > Configuration > Shipping Methods
to configure FedEx.
