authnetcallback.php where do I find this file?

[thuvaslumo]

I'm looking for the authnetcallback.php and I can not find it on our secure server. Where do I find this file? Any help is very much appreciated. -ian

There is no official "authnetcallback.php" file, but that's probably what your programmer called the Silent Post page. Log into your Authorize.net control panel, go to Settings, and click on the Silent Post link, it will give the URL.
