I've been looking at the APIs for UPS, FedEx, USPS, etc, and I can't seem to find any method of pulling all tracking info for a given user. I only see methods that pull info via a tracking number. Has anyone been able to find a way to get at this data? Seems silly to me that these huge carriers wouldn't supply this info in an easy method.
I'm trying to accomplish this in Rails. Any insight would be greatly appreciated. Thanks.
