USPS are releasing an update to their API and price changes on January 17, 2016 that may impact Magento merchants.
See all the details on the USPS price/api changes in our ShipperHQ blog.
Will I be affected?
If you are using standard Magento USPS carrier, you will need to download the updated USPS patch file.
We’ve also updated our extensions for
- WebShopApps Dimensional Shipping
- WebShopApps USPS via Endicia
You can contact us for an upgraded version of your extension (some charges may apply if you are outside of your support period).
