UPS - General Settings
You can find the plugin settings in the WooCommerce menu → Settings → Shipping → UPS.
API Settings In order to show your customers the available UPS services based on the order details, you will need to have a UPS account whose credentials you will have to use to get the plugin working.
Origin Settings By default, the plugin gets the origin rom the WooCommerce settings. You can change this address using a dedicated option.
Weight Unit For the sake of UPS service price calculation, by default, WooCommerce sends the weight value using the unit of measurement taken from the settings. If you encounter any problems with service price calculation and you see the following message "This measurement system is not valid for the selected country”, you can change the unit of measurement for weight for the UPS services. This way, the current weight unit will be recalculated to the unit required by UPS.
Debug Mode Enabling the debug mode will let you identify problems with UPS service price calculation. After you turn on this option, in the cart and order summary you will see error messages related to the data sent to the UPS’s API. Store administrators and managers will also see the very data sent to the UPS’s API.
API Status If the plugin is not able to connect to the UPS’s API, you will see a specific error message.
