I'm trying to build an API integration to ShipStation. I already have a software to manage my orders etc so I just need ShipStation to obtain Label Data. Here are my questions:
* Is it possible to obtain Label Data without creating an order within ShipStation?
* Does ShipStation offer the same carriers for all its customers or does the carrier list vary depending on the contract that customers have with ShipStation?
* What end-points should I be using (as a developer) to test connection and obtain sample label data?
* Is there a WADL/XML/WSDL file that I can use to generate the necessary object structures?
Thanks in advance.
