Click-To-Pay Initial Setup
Our simple iFields integration enables online Click-To-Pay processing through the Cardknox gateway.
This document details the steps necessary to integrate Click-To-Pay with your site.

Register for Click-To-Pay: See [insert link here]
Step 1: Add the iFields.js file after the <head> tag on your payment page:
<script src=https://cdn.cardknox.com/ifields/**ifields-version-number**/ifields.min.js></script>
Step 1: Add the following JS snippet inside the <body> where the Click-To-Pay button is desired.
<div id="click2payContainer">
</div>
Step 2: Create JavaScript object that holds all of the properties/methods required to process Click-To-Pay.
const click2payRequest = {
paymentPrefill: function(){
const result = {
merchantRequestId: "Merchant defined request ID",
currencyCode: "USD",
description: "...corp Product",
orderId: "Merchant defined order ID",
promoCode: "Merchant defined promo code",
subtotal: roundTo(getAmount(), 2),
shippingHandling: "2.00",
tax: "2.00",
discount: "1.00",
giftWrap: "2.00",
misc: "1.00",
setTotal: function() {
this.total = roundTo(
roundToNumber(this.subtotal, 2)
+ roundToNumber(this.shippingHandling, 2)
+ roundToNumber(this.tax, 2)
+ roundToNumber(this.giftWrap, 2)
+ roundToNumber(this.misc, 2)
- roundToNumber(this.discount, 2)
, 2);
delete this.setTotal;
return this;
},
}.setTotal();
logDebug({
label: "paymentPrefill",
data: result
});
return result;
},
paymentCallback: function (payload) {
click2payRequest.setPayload(payload);
},
setPayload: function (value) {
document.getElementById('c2p-payload').value = JSON.stringify(value, null, 2);
showHide("divC2PPayload", value);
}
}
Step 3: Implement desired callbacks.
There are two main callbacks that must be implemented (the rest are optional):
- onPaymentPrefill - calculates total amount and sets transaction information.
- onPaymentSuccess - a callback that will be called after the consumer pays and Click-To-Pay returns a payload with all of the requested consumer information. This is where you need to make an ajax call to your server with the payload. The sample for making an ajax call is below:
Sample Code for Making Ajax Call:
onPaymentSuccess: function(clickToPayResponse) {
return new Promise(function (resolve, reject) {
var xhr = new XMLHttpRequest();
xhr.open("POST", "https://<your domain>/<path to handle authorization>");
xhr.onload = function () {
if (this.status >= 200 && this.status < 300) {
resolve(xhr.response);
} else {
reject({
status: this.status,
statusText: xhr.statusText
});
}
};
xhr.onerror = function () {
reject({
status: this.status,
statusText: xhr.statusText
});
};
xhr.setRequestHeader("Content-Type", "application/json");
xhr.send(JSON.stringify(clickToPayResponse));
});
}
window.ckClickToPay object - controls initialization of Click-To-Pay button
Method | Call Required | Description |
enableClickToPay | Yes | Initializes and enables Click-To-Pay Button. |
Name | Type | Required | Description |
initParameters | Object | Yes | Object that contains initialization parameters for Click-To-Pay |
Enable Click-To-Pay example
ckClick2Pay.enableClickToPay({
environment: c2pEnvironment.sandbox,
externalClientId: "<Your externalClientId>",
click2payContainer: "click2payContainer",
onPaymentPrefill: click2payRequest.paymentPrefill,
onPaymentSuccess: click2payRequest.paymentCallback
});
A server endpoint is needed in order to accept the Click-To-Pay Payload from your website.
Step 1: Create an endpoint and method for API Integration on your server side that takes a Click-To-Pay Payload and makes a call to Cardknox.
For full list of Returned Parameters, please refer to Click-To-Pay Response Reference
Below are the steps to integrate Click-To-Pay with the Cardknox API:
Once the consumer confirms the payment, Click-To-Pay API generates a Click-To-Pay Response in the form of a JSON string.
Integration Steps:
- 1.Set the required fields:
- 1.xDigitalWalletType to ClickToPay
- 2.xClickToPayTransactionId to clickToPayResponse.payload.transactionId
- 3.xClickToPayExternalClientId to clickToPayResponse.payload.externalClientId
- 4.xClickToPayEncryptionKey to clickToPayResponse.payload.encryptionKey
- 5.xCardNum to clickToPayResponse.payload.token
- 6.xAmount to clickToPayResponse.amount
- 7.xCommand - Set to one of the values that starts with cc: like cc:sale, cc:auth, etc.
- 8.xKey to "Your xKey"
- 9.xVersion = "4.5.9"
- 10.xSoftwareName to “Your Software Name"
- 11.xSoftwareVersion to "Your Software Version"
Sample Request:
public async Task<IActionResult> Authorize(clickToPayResponse resp)
{
var reqGateway = new
{
xKey = "Your xKey",
xDigitalWalletType = "ClickToPay",
xAmount = (decimal)resp.amount,
xClickToPayTransactionId = resp.payload.transactionId,
xClickToPayExternalClientId = resp.payload.externalClientId,
xClickToPayEncryptionKey = resp.payload.encryptionKey,
xCardNum = resp.payload.token,
xCommand = "cc:sale",
xVersion = "4.5.8",
xSoftwareName= "Your Software Name",
xSoftwareVersion = "Your Software Version"
};
var respMsg = "";
using (var http = new HttpClient())
{
var resp = await http.PostAsJsonAsync("https://x1.cardknox.com/gatewayJSON", reqGateway);
respMsg = await resp.Content.ReadAsStringAsync();
.....
}
.....
}
