Web SDK Integration for Card Tokenisation Flow

Create encrypted card data#

The requirement is to safely receive card data from the web/mobile app to the backend and tokenize the card using Channex.

1. Add Axios Dependency#

Add axios dependency in your page if you haven’t.

<script src=""></script>

2. Add Card Form HTML#

Add card form in your Html For example:

<div class="card-body">
<div class="form-row">
<div class="col addIcon creditCardIcon">
<label for="CardNumber" id="creditcardnmlang">Credit Card Number</label>
<input type="text" class="form-control" id="CardNumber" placeholder="1234 1234 1234 1234" name="CardNumber" required>
<span id="showCardBasedNum"></span>
<div class="form-row">
<div class="col">
<label for="CardHolderName" id="cardholdernmlang">Card Holder Name</label>
<input type="text" class="form-control" id="CardHolderName" placeholder="" name="CardHolderName" required>
<div class="form-row">
<div class="col-sm-8" style="padding-left: 0px !important;">
<label for="validthru" id="expdatelang">Exp Date</label>
<input type="text" class="form-control" id="validthru" placeholder="MM/YYYY" name="validthru" required>
<div class="col-sm-4 addIcon cvvIcon" style="padding-right: 0px !important;">
<label for="creditCvv" id="cvvlang">CVV</label>
<input type="password" class="form-control" minlength='3' maxlength='3' id="creditCvv" placeholder="..." name="creditCvv" required>
<div class="form-group text-center" style="margin-top: 40px;">
<span style="position: relative; top:25px; cursor: pointer;" onclick="handleCardPay()" class="card-pay" > Submit </span>

3. Submit Form#

On submit the form handleCardPay() function will call and To access Add Encrypted Credit Cards Data API you can add the function to your handleCardPay:

function handleCardPay(){
var cardNumber = document.getElementById("CardNumber").value;
var cardType = 'visa';
// var tokenData1 = "CARD"+new Date().getTime();
var cardHolderName = document.getElementById("CardHolderName").value;
var cvv = document.getElementById("creditCvv").value;
var expiry = document.getElementById("validthru").value;
encryptedCreditCards(cardNumber, cardType, cardHolderName, cvv, expiry);
function encryptedCreditCards(cardNumber, cardType, cardHolderName, cvv, expiry){
let environment = 'sandbox';
let jwtToken = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJTZ2xmZnl5WmdvakVkWFdMIiwiaXNzIjoiQ0hBSVBBWSIsImlhdCI6MTY5NTE0NTQ1MiwiZXhwIjoxNzk1MTU1NDUyfQ.G1-XudagfPVvGZYTEISNYrLJjGmZVZMtIUCq5uD0B3g'
let card_details = {
"cardholder_name": cardHolderName,
"card_type": cardType,
"service_code": cvv
let jwt_token = getJWTToken();
let chaipay = new window.ChaiPay({
chaiPayKey: common.test_chaipay_key
chaipay.paymentService.postCreditCards(jwtToken, environment, card_details ,function(error) {
