Why Magento UPS Rates Fall Short

Legacy UPS XML / Web Services paths age poorly, and generic table rates rarely match what UPS will actually charge for a carton:

• Wrong checkout quotes — customers see one price, then invoices another
• Auth churn — older UPS APIs and keys get deprecated; OAuth REST is the modern path
• No diagnostics — when rates disappear, Magento gives little carrier-side detail
• Service clutter — every UPS method appears even when you only want Ground + 2nd Day

What This Extension Solves

The UPS REST API Shipping Extension talks to UPS with OAuth and returns live rates in cart and checkout for Magento 2.4 stores.

• Real-time UPS shipping rates in cart and checkout
• Secure OAuth authentication (Sandbox & Production)
• Negotiated account rates when UPS enables them
• Allowed services and country restrictions
• Dimensional weight support for fairer carton quotes
• Admin Test Connection and Test Sample Rate tools with optional debug logging

Key Features

• Sandbox and production credential scopes
• Filter which UPS services appear at checkout
• Works alongside other Towering Media carriers (USPS, FedEx)
• Open Source & Adobe Commerce Magento 2.4.x
• Hyvä-friendly carrier layer (no Knockout dependency)

System Requirements

• Magento: 2.4.4 – 2.4.7+ (Open Source & Adobe Commerce)
• PHP: 8.1, 8.2, or 8.3
• Towering Media Composer repository credentials
• UPS Developer account with REST / OAuth credentials

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-ups-rest-api

Step 3: Enable and upgrade

php bin/magento module:enable Toweringmedia_UPSRestApi
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.

Configure UPS in Admin

1. Log in to Magento Admin.
2. Go to Stores → Configuration → Sales → Delivery Methods (or the Towering Media UPS REST section shown in the wiki).
3. Enable the UPS REST method and set title / sort order.
4. Enter Client ID, Client Secret, and account / shipper details for Sandbox or Production.
5. Choose allowed services, countries, and dimensional-weight options.
6. Save Config and flush cache.

Test Connection & Sample Rates

Use the admin tools before relying on live checkout:

• Run Test Connection to confirm OAuth succeeds
• Run Test Sample Rate with a representative origin/destination and weight
• Add a product to cart on the storefront and confirm UPS methods appear
• Place a staging order and verify the selected method persists on the order

Troubleshooting

No UPS methods at checkout

• Confirm the carrier is Enabled and saved at the correct store scope
• Check allowed countries / postcodes vs the quote address
• Review debug log for UPS API error text
• Flush Magento cache after config changes

OAuth / authentication errors

• Regenerate Client Secret in the UPS developer portal
• Confirm Sandbox vs Production endpoints match the credential set
• Ensure server time is accurate (skew can break tokens)
