Secure Fields (JS)
The only payment form you’ll ever need
Secure Fields allow you to securely collect credit, debit and virtual cards as well as bank account data by injecting iframes to your DOM. A separate iframe for all sensitive values is used. Thereby, the data never touches your server and allows you to capture all the other related payment data such as cardholder name, expiry date, etc. directly by yourself.
Using Secure Fields qualifies you for SAQ A.

In order for Secure Fields to insert the card number and CVV iframes at the right place, create empty DOM elements and assign them unique IDs. In the example below those are:
card-number-placeholdercvv-placeholder
For the bank account example they are:
iban-placeholderaccount-number-placeholderbranch-number-placeholder
Card Number / CVV
IBAN
Account Number / Branch Code
<form>
<div>
<div>
<label for="card-number-placeholder">Card Number</label>
<!-- card number container -->
<div id="card-number-placeholder" style="width: 250px;"></div>
</div>
<div>
<label for="cvv-placeholder">Cvv</label>
<!-- cvv container -->

Start with creating a new Secure Fields instance:
var secureFields = new SecureFields();
// Multiple instances might be created and used independently:
// e.g. var secureFields2 = new SecureFields();
Initialize it with your
merchantId and specify which DOM element containers should be used to inject the iframes:Card number / CVV
IBAN
Account number / Branch Code
secureFields.initTokenize( "1100007006", {
cardNumber: "card-number-placeholder",
cvv: "cvv-placeholder"
});
secureFields.initTokenize( "1100007006", {
iban: "iban-placeholder"
});
secureFields.initTokenize( "1100007006", {
accountNumber: "account-number-placeholder",
branchCode: "branch-code-placeholder"
});
Afterwards, add optional
expm and expy, submit the form and listen for the success event:$(function() {
$("#go").click( function() {
secureFields.submit({ // submit the "form"
expm: 12,
expy: 26
});
});
});
secureFields.on("success", function(data) {
if(data.transactionId) {
// transmit data.transactionId and the rest
// of the form to your server
}
});
Instances can be destroyed if no longer used:
secureFields.destroy();
Once you've transmitted the
transactionId to your server (together with the the rest of your form) you have to execute a server to server POST request to retrieve the tokenized card or bank account values.This service requires HTTP basic authentication. The required credentials can be found in our dashboard. Please refer to API authentication data for more information.
