Account Boarding Merchant Agreement

Overview

In order to be boarded every Merchant needs to agree to Go Plus Terms and Conditions. To help Developers integrate Agreement API into their website we are supporting Agreement API through Cardknox iFields.

Integrate Agreement API using ifields

Obtain your iFields xKey from your Cardknox Partner Portal account settings.

Adding Reference to iFields

Step 1: Check the latest stable iFields version here: https://cdn.cardknox.com/ifields/versions.htm

Step 2: Add the ifields.js file after the <head> tag on your website:

<script src=https://cdn.cardknox.com/ifields/**ifields-version-number**/ifields.min.js></script>

Adding iFrame and JavaScript Objects for Merchant Agreement

Step 1: Add the following iFrame JS snippet inside the <body> where Merchant Agreement is desired.

Make sure you have an attribute data-ifields-id="agreement" as part of <iframe> tag

<iframe id="agreement" class="agreement" data-ifields-id="agreement" src="https://cdn.cardknox.com/ifields/**ifields-version-number**/agreement.htm"></iframe>

Step 2: Create JavaScript function to handle Agreement API callback

function handleAgreementResponse(response) {
    let msg = null;
    if (!response) {
        msg = "Failed to load token. No Response";
    } else if (response.status !== iStatus.success) {
        msg = "Failed to load token. "+response.statusText || "No Error description available";
    } else if (!response.token) {
        msg = "Failed to load token. No Token available";
    } else {
        msg = response.token;
    }
    setTimeout(() => {alert(msg)}, 10);
}

For response object reference refer here: Agreement Response

Step 3: Enable Customer Agreement to get the token

There are two ways to get the token:

Asynchronously (a callback will be performed once the customer agrees to Terms and Conditions) Just add enableAgreement call when the document is loaded (autoAgree the parameter is set to true):

document.addEventListener("DOMContentLoaded", function(event) {
    ................ 
    ckCustomerAgreement.enableAgreement({
        iframeField: 'agreement',
        xKey: '<Your ifields xKey>',
        autoAgree: true,
        callbackName: 'handleAgreementResponse'
    });
    ................    
}

Synchronously (Explicitly calling getToken function for example on Submit) Add enableAgreement call when the document is loaded (autoAgree the parameter is set to false):

document.addEventListener("DOMContentLoaded", function(event) {
    ................ 
    ckCustomerAgreement.enableAgreement({
        iframeField: 'agreement',
        xKey: '<Your ifields xKey>',
        autoAgree: false
    });
    ................    
}

In your Submit function add the following code:

ckCustomerAgreement.getToken()
    .then(resp => {
        handleAgreementResponse(resp);
    })
    .catch(err => {
        console.error("Agreement Token Error", exMsg(err));
        handleAgreementResponse(err);
    });
