WooCommerce Stamps.com API

WooCommerce Stamps.com API is a WooCommerce plugin that connects your store to a Stamps.com account so you can create USPS shipping labels from the order screen. It builds labels from the items in an order, verifies addresses, and lets you manage postage and labels without leaving the WordPress dashboard. It does not show shipping rates to customers at checkout.

Key Features

• USPS label printing – You can generate ready-to-print USPS shipping labels directly from an order in the WooCommerce admin, based on the items the customer bought.
• Address verification – The order meta box includes Stamps.com address verification so you can check a shipping address before creating the label.
• Account monitoring – You can watch your Stamps.com account balance and postage from inside the WooCommerce admin.
• Label refunds and deletion – Shipping labels you created through Stamps.com can be refunded or deleted from the WooCommerce admin.
• Automatic postage funding – An Automatic Funding option buys postage for you when your balance falls under a threshold you choose.
• Discounted USPS rates – Labels are created with discounted USPS rates on domestic and international Priority Mail and Priority Mail Express shipments.
• Discounted package insurance – Stamps.com package insurance is offered at a discount compared with standard USPS insurance rates.
• No checkout rates – The extension does not display USPS rates to shoppers during checkout; showing those rates requires the separate USPS Shipping Methods extension.

Who Is It For

This plugin is for WooCommerce store owners who ship orders within the United States and already use, or plan to open, a Stamps.com account for postage. It suits shops that want label creation and postage management handled from the order admin rather than a separate shipping tool.
