Welcome to WebmasterWorld colin_uk, I have to say I don't know what callback is and I couldn't find it on their site. I did a search for worldpay callback on google and found a few examples. Do they not have documentation that you can read through to understand it better?

Hi colin_uk I have just completed a WorldPay callback for our installation. Basically, you need to log into WorlPay's CMS, and edit your installation's configuration. There you can specify to use a callback by checking callback enabled, and you can enter the callback's full URL. When your callback is called, the POST variables will contain various variables such as the world pay transaction ID and whether the transaction was successfull or cancelled. Eric

If you speak to support, you can also process or ignore the transaction using the call back. You need to have a pre-auth account to do this (you need to ask - it's free), which means you have to manually review the transactions and process them by hand. With a call-back you can decide what to do, using the vars sent (as described in previous posts), so you may decide to manually check those or block those where the credit card security does not match or country does not match for example. You could also block particular addresses (physical or email), phone numbers as so on... This may help cut down on fraud attempts.
