reading product Dynamically while running a service call

reading product Dynamically while running a service call

Hi

Following is the Scenario I am trying to implement

When ever an order is placed in my word press site that details should be reflected in my ZOHO Sales order

For this I have used the XML feed which is in Developer space => Examples => sales order


my problem is how to read product ID while service call

i.e when ever an order is placed and service call is executed how to pass product ID dynamically
