Integrates USPS REST API Shipping Rates

Integrates USPS REST API Shipping Rates is a powerful extension that integrates the latest USPS REST API with your Magento store to provide accurate, real-time shipping rates during checkout.

With this extension, store owners can securely connect their Magento store with USPS by configuring the USPS Client ID and Client Secret. Once configured, the extension automatically retrieves available USPS shipping services and their rates based on the customer’s shipping address.

Customers can view multiple USPS shipping options such as Ground Advantage, Priority Mail, Media Mail, and other supported USPS services directly on the checkout page. This helps provide transparent shipping costs and improves the overall customer checkout experience.

The extension is built using Magento’s core shipping framework, ensuring seamless integration, high performance, and compatibility with Magento 2 stores.

This extension was specifically developed to support the new USPS REST API, as USPS has deprecated its older USPS Web Tools API (XML-based API) that was previously used for retrieving shipping rates. By adopting the modern REST-based integration, the extension ensures your Magento store continues to fetch USPS shipping rates reliably and remains compatible with USPS’s latest API standards.

No changes are required to your store’s workflow or checkout process; this extension only helps fetch accurate USPS shipping rates using the new REST API, so your customers’ experience remains the same while keeping your store up-to-date with USPS services.
