Unlock Seamless Shipping with Magento 2 UPS Shipping Carrier Powered by REST API
Shipping is at the heart of any e-commerce business. For Magento 2 store owners aiming to streamline order fulfillment and offer customers real-time shipping rates, the “Magento 2 UPS Shipping Carrier with Rest API” plugin by EcomPlugins is a game-changer. This comprehensive guide explores the need for RESTful UPS integration, the underlying API logic, critical features, step-by-step configuration, and trending FAQs as of 2025.
What is Magento 2 UPS Shipping Carrier with Rest API?
The Magento 2 UPS Shipping Carrier with Rest API module allows Magento merchants to fetch real-time UPS shipping rates directly at checkout. The extension leverages UPS’s latest OAuth 2.0 secured REST API to guarantee compatibility and compliance—crucial because UPS has permanently retired the old SOAP/XML APIs as of June 2024. This plugin is not an official UPS product but is built by EcomPlugins to provide seamless API integration, accurate rate calculations, and powerful shipping features for stores running on Magento Community, Commerce, and Cloud versions 2.3.x and 2.4.x.
Why REST API Integration Matters in 2025
The End of UPS SOAP/XML APIs
UPS’s transition from SOAP/XML APIs to RESTful interfaces in June 2024 means that all merchants must use the new API endpoints and OAuth 2.0 authentication. Without upgrading, shipping rates cannot be displayed, resulting in lost sales and checkout failures.
Key Implications:
Security: REST API with OAuth 2.0 ensures secure, token-based authentication.
Reliability: RESTful architecture is more robust, scalable, and future-proof.
Real-time Rates: Only REST API endpoints return updated, account-level and discounted rates.
Core Features
At checkout, the plugin collects the following data:
Package weight (up to 150lbs per package)
Customer shipping address
Origin warehouse (configured in admin settings)
Product-level dimensions (height, width, length)
Packaging logic (box count, ship-separately flag)
Special shipping rules (free shipping, minimum/maximum weight)

Trending FAQs for 2025
1. Why isn’t my UPS integration working after June 2024?

Yes. The plugin allows you to disable UPS quotes on the frontend, showing them only in admin/admin quotes and orders.
