Storing your customer’s card data dramatically increases your repeat-custom conversion rate, but it can also introduce additional risks along with a PCI DSS overhead - these are mitigated by tokenizing the card data. CyberSource replaces your customer’s card data with a token that can be used only by you.
Secure Acceptance Flexible Token API provides a secure method for tokenizing card data and reducing your PCI DSS burden. Card data is encrypted on the customer’s device and sent directly to CyberSource, bypassing your systems altogether.
This SDK simplifies the client-side integration and enables:
Install the package with:
yarn add @cybersource/flex-sdk-web
# or
npm install @cybersource/flex-sdk-web --save
The SDK is exposed as a UMD providing compatibility with most module loader specs or direct use in the browser via a script tag.
import flex from '@cybersource/flex-sdk-web';
const options = {};
flex.createToken(options, response => {
// use response
});
OR
<html>
<body>
<script src="./YOUR_ASSETS_PATH/flex-sdk-web.js"></script>
<script>
var options = {};
FLEX.createToken(options, function(response) {
// use response
});
</script>
</body>
</html>
Full documentation is located in the /docs folder at the root of the installation directory.
The SDK is non-prescriptive on your payment flow design, making few assumptions about your development stack. It is easily integrated into any front-end setup. Described below is a minimal example for a web app using full page refreshes and form POSTs.
<!-- checkout template -->
<html>
<body>
<form id="paymentForm" action="/your/server/endpoint" method="post">
<input type="text" id="cardNumber" />
<input type="text" name="securityCode" />
<input type="text" name="cardExpirationMonth" />
<input type="text" name="cardExpirationYear" />
<select name="cardType">
<option value="001">VISA</option>
<option value="002">MasterCard</option>
<option value="003">AmericanExpress</option>
</select>
<input type="hidden" name="token" />
<button type="button" id="payBtn">Pay Now</button>
</form>
<script>
var jwk = {
/* flex public key in jwk format */
};
</script>
<script src="integration.js"></script>
</body>
</html>
// integration.js
import flex from '@cybersource/flex-sdk-web';
document.querySelector('#payBtn').addEventListener('click', () => {
const options = {
kid: jwk.kid,
keystore: jwk,
encryptionType: 'RsaOaep', // ensure this matches the encryptionType you specified when creating your key
cardInfo: {
cardNumber: document.querySelector('#cardNumber').value,
cardType: document.querySelector('select[name="cardType"]').value,
cardExpirationMonth: document.querySelector('input[name="cardExpirationMonth"]').value,
cardExpirationYear: document.querySelector('input[name="cardExpirationYear"]').value
}
};
flex.createToken(options, response => {
if (response.error) {
alert('There has been an error!');
console.log(response);
return;
}
document.querySelector("input[name='token']").value = response.token;
document.querySelector('#paymentForm').submit();
});
});
Note that the SDK can easily be integrated into a single page application, using AJAX for the key fetch and token submission.
Note that Safari 10 and below does not support an encryptionType of RsaOaep256
