I am currently using Magento ver. 1.5.0.1. Can anyone tell me how do i create a sub category using soapv2. Here my code format category_data = { "name" => "LIGHTING", "is_active" => 1 } soap.call('catalogCategoryCreate',session,4,category_data,1, "include_in_menu") I got some errors when i run this code. : Attribute "include_in_menu" is required. (SOAP::FaultError) Is that any solution for this problem. Thanks.
