Web SDK Core

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

The library is used by the Merchant on their website. A list of payment form parameters (mdOrder, pan, expiry, 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(
    {
      pan: '4111111111111111',
      cvc: '123',
      expiryMMYY: '12/24',
      mdOrder: '63447c9c-b432-7c8e-962f-161c0008f9da',
      // pubKey: '-----BEGIN PUBLIC KEY-----MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAioZS/AN/xWtZsQNFjOc8VjKnE5xwQuT0zV0q2j2JpBN66We1+dya9gfqt14Mg53tHfvTB+hbHpmK8mYlPdpZXnIIN3TuBv9llfwmAMm4pFRDG8KeIgOVLSGptHufjwoh2iE4YfxZWgCbnkqjDk6YiTPdy+W7nxF+fPUEsFE1YJDTRwzVqpsbjfKW9tQAjDxpAwfsiyhk0NzTEsDahWtjk1+WaqqrN0LRQgtaTnnbjSr3npmegu63mgTXBX1MT5olRY+BjCaPCZLt+6sFNd/wVI+UBo3/U6jHEHVe3T1vdZWNhJe2twFzrSSpm5aevDK7OpQzMT7v2wUIRWIlFvIxFwIDAQAB-----END PUBLIC KEY-----',
