About This Plugin

WooCommerce Stamps.com API creates ready-to-print shipping labels for USPS, UPS and other carriers, based on the items in an order. Labels are created from the backend order admin. You can also process refunds for and delete Stamps.com shipping labels, and top up your Stamps.com account.

The extension does not show shipping rates to customers at checkout. To show USPS rates on the cart and checkout pages, you also need the USPS Shipping Methods extension. Used together, customers see the same rates at checkout that you use when creating labels.

It needs a Stamps.com account and server SOAP support.
