I want to link Nexternal with UPS and Fed Ex to get real time rates but I do not want to generate shipping labels through Nexternal. How do I do that?
Response:
UPS imposes the rule that if their Real Time Rates are in use, you may not display those rates and rates from another carrier together (FedEx for example) for any given shipping zone. If you decide to activate the appropriate Real-Time Rate (RTR) for FedEx or UPS (not both), you can find this option at Edit Shipping (Page 3) from Settings/Shipping.
