World Pay Business Plugin - Payment Response URL

The World Pay Business Plugin has options for statuses for confirmed, pending etc, which suggests that the plug-in accepts a call back from the world pay gateway.

On the the world pay control panel there is a option for a "Payment Response URL".

What the url please?

Thanks

Indeed there is a callback. But the URL is given automatically to World Pay if the option "allow notifications from RBS Worldpay Business Gateway" of the plugin is activated. So you don't need to enter it on World Pay's control panel.
