Switch to using the ShipStation API
In the documentation there are two ways to connect to ShipStation: https://www.shipstation.com/developer-api/
We currently use the Custom Store Integration which limits the amount of information we can send to ShipStation. There is also another option to use the ShipStation API, which offers a lot more field / features. Should we be switching to the API to allow better communication between the two?
A concrete example is sending over line item dimensions or possibly the dimensions of the package for the shipping rate. This is not possible with the Custom Store Integration, but is supported in the API.
