Important Information

To simulate a KYC failure, please send "999999999" as the Federal Tax ID. When the click-to-agree form is submitted with this value, the KYC checks will fail, and the account will be placed into the Risk status.

IFrame Integration

Example IFrame

            
<iframe>
    src='https://enroll.usiopay.com/click_to_agree.aspx?id=DD7939C9-E50C-450A-8509-D7259C4E984D&embedded=TRUE'
    frameborder='0'
    onload='scrollTo(0,0)' 
    style='background: rgba(0, 0, 0, 0.5);margin: 0px;padding: 0px;allowtransparency=true;'
</iframe>

Event Listener Example

            
<script>
    function receiveMessage(event)
    {
        //your business logic goes here
        alert(event.origin); //"https://enroll.usiopay.com"
        alert(event.data);   //"Completed"
    }
    
    window.addEventListener("message", receiveMessage, false);
</script>

When the click to agree page is embedded in an iframe, it will communicate with the containing page using the JavaScript window.postMessage() method to send events containing a pre-defined string. This allows the containing page to react to events as they occur (e.g., by directing to a new page once the submmited form is received). Events include a string that allows the containing page to notify it the click to agree form has been submitted.

Using JavaScript, the containing page can receive the notification and consume the data it contains by listening for the message event on the global window object and reacting to it as needed. The data passed by this click to agree page notification is represented as string in the data string property of the listener method's event argument.

URL

SOURCE https://enroll.usiopay.com/click_to_agree.aspx?id={Your GUID goes here}&embedded=TRUE

Response

The response is represented as string, the response can be read in the data string property of the listener method event argument as showed in the example.

"Completed" : string
