Hi Pankaj,
You will have to create a transaction to capture the Customer Response.
Why are u hesitating to create a transaction ?
It would be very easy to capture and retrieve the data from transaction. You can use <b>CRM_ORDER_READ</b> function module to retrieve the transaction data.
There is also a report CRM_ORDER_READ which uses the CRM_ORDER_READ function module internally.
<b>Reward points if it helps.</b>
