API additions

[ryan35]

The ability to create/edit batches via API and also the ability to split orders via API would be pretty useful. Not having these features currently causes significant delays in our business operations, and we'd love for ShipStation to be the solution to that.

Second this.

Yes, we also need this addition. Is this now available? We're looking for a way to automate the splitting and assigning of orders to each available warehouse. Our dev can write this in our middleware, but does Shipstation allow this via the API?
