How to insert Test Configuration data in HP ALM

I am trying to insert data in Test Configuration tab of Test Plan through OTA APIs.

I referred HP ALM OTA API Reference Guide to look for Interface for inserting Test Configuration data.

Interfaces provided for Test Configuration(eg: ITestConfigFactory,ITestConfig etc) are all deprecated.I can't use them.

However,I am able to create Test Configurations through HP ALM front end.

Need to know the Interface to insert Test Configuration data through API or table/column name in which I can insert using .field() methods.

Any help would be greatly appreciated.

Thanks
