API for our business

Hello Team,

What API version should we use? Our use-case is that we need to create Shipment in EasyShip through API. This shipment should be shipped directly and print labels (with just one click of button on our system).

I noticed that only v1.0 has this "Create a shipment and buy label". How can we Ship the shipment from API and what's your best advise?

Thank you very much!
