Does ShipBlink/EasyPost support Paperless Trade (PLT)? EDI? AES?

What is EasyPost? EasyPost is an API Developer Solution that allows ShipBlink to integrate with hundreds of carriers with ease. EasyPost is free to use, and ShipBlink requires an EasyPost account to start printing labels for your store.

EasyPost says:

We support PLT for DHL and EDI for FedEx and UPS.

As far as AES goes, you can file the information at AESDirect and get a number. That number goes into the CustomsInfo object in the eel_pfc field, which then gets transmitted to the carrier. From that point, whether or not the data is submitted electronically is up to the PLT/EDI support.
