1.3.24 WooCommerce Stamps.com API
The first i Stamps.com integration automatically creates USPS ready-to-print shipping labels based on the items in the order. Stamps.com seamlessly accesses the latest USPS rates as labels are created, providing you with unprecedented reliability, ease of use and speed.
This extension does not display shipping rates to your customers during the checkout process. If you wish to display USPS rates on the shopping cart/checkout page of your website, you will also need to purchase the USPS Shipping Methods extension. Using both extensions in combination, your customers can see the best rates at checkout, and you can take advantage of those same rates when creating shipping labels through back-end order management.
