UPS - Live Rates
You can choose Rates type to be either Live or Custom.
You can select the option while configuring a shipping method:
Live rate means you don't have to provide any pricing for shipping. FS Connect checks the pricing of a shipment directly in UPS' system via API. This way you can always get the right pricing. During the checkout process, you will charge your customers the same amount UPS wants from you. Automatically!
Live rates work for both domestic and international shipments.
By default, all available UPS services are enabled. You can disable some of them. Mark Custom services checkbox. Next, disable services you don't want to be available in your store.
