We have a form on our website that's for CC authorization/validation. It's coded in PHP. Credit cards get charged via Authorize.net for $1 but the charges remain unsettled/pending instead of dropping the charge or voiding it. I called tech support and the representative said Authorized.net needs a "second call" from the website to void the charge. My question is how do I add the code to do that?
I found this page which looks like what I need but I don't know how to customize it or where to add it. Please help.
