I’m using SOAP to add a shipment to a Magento order but I need to have the ability to modify existing shipments, and add additional shipments.
I can add a shipment and a track # but if the user voids a shipment for some reason I’d like to remove the shipment and then create a new shipment. I don’t see a way to do this.
If I just try to add another shipment then I get a SOAP error.
Uncaught SoapFault exception:  Cannot do shipment for order
