I am looking to get the current FedEx rates for a package dynamically from my Flex app. I was hoping to do this without using CF, php, etc. Would this be possible using just actionscript to set up? Using a WebService or URLRequest possibly. Any help would be appreciated.
How does Fedex makes the rates available? Do they have some form of web service / SOAP or REST API?
If so, do the API URLs have a crossdomain.xml file that allows remote SWFs to access it? OF so, you're good to go. IF not; you'll have to convince FedEx to add a crossdomain.xml file allowing you to get their data from the Flash Player.
Both FedEx and UPS have APIs
