Why FedEx Quotes Go Wrong

Legacy FedEx SOAP/XML integrations and guesswork table rates create margin leaks:

• List vs account confusion — shoppers see list rates while you ship on negotiated contracts
• Auth failures — older keys expire; OAuth2 is the modern FedEx REST path
• Dimension gaps — missing L×W×H inflates or zeros dimensional weight
• Too many methods — cluttered carrier lists slow checkout decisions

What This Extension Solves

The FedEx OAuth REST API Shipping Extension returns real-time FedEx rates via OAuth2 for single-origin fulfillment.

• Real-time FedEx rates in Magento cart/checkout
• OAuth2 with sandbox and production credentials
• Negotiated (ACCOUNT) and LIST rating from one configuration
• Allowed methods, pickup type, Top-N output, optional transit time
• Shared package dimensions and dim-weight modes for large catalogs
• Admin credential validation, sample-rate testing, optional debug logging

Key Features

• Built for Magento 2.4 Open Source & Adobe Commerce
• Works with Hyvä and React Checkout Pro rate collectors
• Companion Dry Ice add-on available for specialized SKUs
• Pairs with UPS / USPS REST modules

System Requirements

• Magento: 2.4.x
• PHP: 8.1–8.3
• FedEx Developer Project with REST OAuth credentials
• Towering Media Composer access

General Composer install steps for Towering Media modules: Installation guide.

Installation Overview

Step 1: Authenticate Composer

Add your Towering Media credentials to auth.json in the Magento root (same pattern as other Towering Media extensions).

Step 2: Require the package

composer require toweringmedia/module-fedex-rest-api

Step 3: Enable and upgrade

php bin/magento module:enable Toweringmedia_FedExRestApi
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

Exact module enable name may match your package’s registration.php / module.xml—confirm in the package after install. Production stores should follow your normal deploy process.
