I just checked some ActionScript 3 libraries into to Google code for accessing the FedEx web APIs. They aren’t 100% complete, but they support a fair amount of functionality like:
- Tracking packages.
- Shipping packages.
- Deleting shipments.
- Registering for meter numbers.
- Request a Signature Proof of Deliver.
The package is checked in as as3fedexlib. I expect to be adding additional functionality over time.
