If the merchant gateway supports 3D Secure (also known as Verified by Visa or MasterCard Secure Code), then it can be utilized within WHMCS.
- Add a function to the module named yourgatewayname_3dsecure
- Return the HTML for the
<form>post method to take the user to the 3D Secure process. An example of this is below:
The _3dsecure function is passed all the same variables that the _capture function is. The return url should be a callback file to handle the response.
<?php
function yourgatewayname_3dsecure(array $params = array()) {
return '<form method="post" action="https://www.gateway.com/3dsecure/">
