Shipworks has a Generic Store where we can specify our own URL to which it connects. I wrote a PHP code which accepts ShipWorks XML request, gets the response from OpenERP through XML-RPC and then send back the response to ShipWorks in ShipWorks compatible XML format.
Following call have been implemented –
1) GetModule
2) GetStore
3) GetStatusCodes
4) GetCount
5) GetOrders
6) Update Status
7) Update Shipment
