But this code does not tell how to retrieve response from world pay.

Suppose i have completed one transaction successfully in world pay.

I get one transaction id and one reference id.

Now i want to fetch that value in my web page.

but i dont knw how to get it and how to redirect to my website

Hi folks,

Currently I am developing a shopping cart in which i need worldpay
integartion. I also want customer to be redirected to my web site
after transaction. Worldpay also provide default pages for that
purpose but i need a customized page on which customer will be
redirected after transaction. So do any one have a code snippet which
can assist me in integration.
