You can reach the plugin settings by choosing the WooCommerce → Settings → Shipping → USPS Live Rates from the sidebar.
API Type
It is possible to connect with a USPS API through:
- REST API
- Fill in Consumer Key and Consumer Secret – see our guide on how to obtain them.
- Web Tools API (deprecated)
- Fill in this field with the credentials you acquired during the USPS account registration process.
PRO Custom Origin
– use this option to use the different shipper’s address to calculate the live rates than the one defined in the WooCommerce settings. It is especially useful e.g. when you ship the products directly from the warehouse located in a different place than your shop’s address.
If not enabled, the address you’ve entered at WooCommerce → Settings → General → Store Address will be used by default. If ticked, the additional Origin Address, Origin City, Origin Postcode and Origin Country/State fields will appear below.
Please be advised that each shipping method that uses USPS plugin can have its own Custom Origin. To learn more about Multiple Custom Origins feature – read this article →
