Enabling security code verification with your own form

You can enable security code verification while saving a card token with the iframe, with your own form, or through the API.

  1. Prepare the Iframe

    Follow steps 1-6 of the Creating a save card page with your own form tutorial.

  2. Request a One-time-use Token

    Request an e-commerce one-time-use token. Include the object "processingOptions": { "verifyCvc": true } in the body of your request. (This is part of step 7a of the Creating a save card page with your own form tutorial, with the addition of the verifyCvc parameter in the processingOptions object.)

    curl -X POST https://api.nexiopaysandbox.com/pay/v3/token \
      -H 'Content-Type: application/json' \
      -H 'Accept: application/json' \
      -H 'Authorization: Basic [Base64_encoded_login]'
      -d '{
      "processingOptions": {
        "verifyCvc": true
      }
    }'
    

  3. Post Card Information to Nexio

    Follow step 7b of the Creating a save card page with your own form tutorial.

    In the request, be sure to also include the card security code (as the securityCode parameter) as entered by the user.

    curl -X POST https://api.nexiopaysandbox.com/pay/v3/saveCard \
      -H 'Content-Type: application/json' \
      -H 'Accept: application/json' \
      -H 'Authorization: Basic [Base64_encoded_login]'
      -d '{
      "token": "eb50a022-d6de-4244-a1e6-dcb8522b2d19",
      "card": {
        "cardHolderName": "John H Doe",
        "encryptedNumber": "cu3yRktaYFK2LUC6DpNK289tYDsGRCi7cO+GeG0hkeYFvT7Y8/oY5r53obMz6Q/BZ38gk2u2Ufwy8ojBcX2sfNjG5jplGTXA4NNlSIUjMFfiHe1sff1JFpThoiW/IIlifGlbWu+S1/9pqWPTzJ2+DcjwohbHzsDahhYewFhXgC8qsK0ypi/Shlp+CwRITyIvbVXESD0xz3YOTRHeZLlChvVqN8z4ZzN8nm0MXkmT1wcpYI73bH4KdnPwNU3s7XxvP/ernQP73SHHAOKSLlz4F6AEHFjJiCoXzeLF7LwEjRdxDJ0sKVXbRk3i9BGh+8Nle2VYgjpUWtk2763QkvZiQQ==",
        "expirationMonth": "12",
        "expirationYear": "20",
        "securityCode": 927
      }
    }'
