Web SDK Core

Library for generating cryptograms from data received from the payment form. The library generates the response asynchronously! A webhook is used to get the result.

The library is used by the Merchant on their website. A list of payment form parameters (pan, expiry, cvc, etc.) is passed to the library, and the output is a cryptogram ready for transfer to the acquiring backend.

Example of use

<script src="https://dev.bpcbt.com/payment/modules/card-kit-core/card-kit-core.js"></script>
<script>
  window.CKCToken.generateWithCard(
    {

      cvc: '123',
      expiryMMYY: '12/24',
