The correct format depends on the server.

Maybe:

Job2.PostString("http://192.168.1.239/WebServicesula/Service.asmx/Delete", "customerId=123")

If it expects a json string then you need to use JsonGenerator to create the string.

@Makumbi

Dim jgen As JSONGenerator
    jgen.Initialize(CreateMap("customerId": 123))
Job2.PostString("http://192.168.1.239/WebServicesula/Service.asmx/Delete", jgen.ToString)
