USPS Rates API Plugin Update Posted – September 23, 2015

We have posted an update to the United States Postal Service shipping rates API plugin. This update fixes an issue where the USPS rate system would return incorrect rates for non-domestic shipments under a specific setup | configuration.

If you are using USPS rates on the API version of the cart, it is recommended that you download and install (update) the plugin via the URL below. Note: This update does not affect or apply to carts installed prior to January 12, 2015 or carts running the previous PHP platform.

If your cart version ends with an “i” such as 2.1501i and you are using USPS for real-time shipping rates, you should apply this update as soon as possible to your installation(s) to avoid any shipping rate errors.
