Date Updated: 7/24/2021

An update to CardSecure was deployed to the UAT environment on 7/19/2021 and to the production environment on 7/24/2021.

This release includes internal fixes and updates to CardSecure, including the following enhancement:

Enhanced Apple Pay Support

When tokenizing an Apple Pay payload, CardSecure no longer requires a specific order for the Apple Pay parameters in the devicedata string, with the exception of the data value, which must be the first parameter in the string. Previously, CardSecure required a specific sequence for all Apple Pay parameters in the devicedata string to correctly parse the string.

See the Apple Pay Developer Guide for detailed information on integrating Apple Pay support.

Date Updated: 2/6/2020

This release includes the following updates:

Apple Pay Support

The CardSecure API now supports tokenizing Apple Pay payment tokens. Previously, this was only supported using the legacy API HTTP methods.

To tokenize Apple Pay payment tokens, make a request to the tokenize endpoint using the Apple Pay payment token parameters in the devicedata field, and specify EC_APPLE_PAY in the encryptionhandler field, as follows:

POST /cardsecure/api/v1/ccn/tokenize HTTP/1.1
Content-Type: application/json

{
  "devicedata" : "<Apple Pay payload>",
  "encryptionhandler" : "EC_APPLE_PAY"
}

See the tokenize description for a complete example, and see the Apple Pay Developer Guide for detailed information on integrating support for Apple Pay, and formatting the payment token string for CardSecure.

Update a Token with CVV and Expiry

The CardSecure API now supports the ability to update a payment card token to include the CVV and expiration date associated with the card.

Note: If you use a card reader or terminal to capture track data, you should not use this method. Updating the token may delete the track data, making the token unusable.

To update a token, make a subsequent request to the tokenize endpoint using the token in the account parameter, and include the cvv and expiry parameters, as follows:

POST /cardsecure/api/v1/ccn/tokenize HTTP/1.1
Content-Type: application/json

{
  "account" : "9417119164771111",
  "expiry" : "1122",
  "cvv" : "123"
}

CardSecure API Changelog

RESTful Implementation

The CardSecure RESTful web service uses the JSON (JavaScript Object Notation) method of encoding data for transmission via the HTTP network protocol. Most programming languages have libraries to convert an arbitrary object to and from a JSON data transfer encoding.

The CardSecure API provides a library of POST operations used to submit HTTP requests to the web service. Responses are returned in JSON objects. See CardSecure API Service Endpoints for detailed information on the supported request types and corresponding responses.

Tokenizing and Encrypting PAN Data

You should only use CardSecure to programmatically handle and tokenize clear payment account numbers (PANs) if your business is a registered PCI Level 1 or Level 2 certified merchant. If you are not already certified for compliance with the Payment Card Industry's standards and guidelines for handling sensitive account data, see https://www.pcisecuritystandards.org/ for more information.

Additionally, you can integrate the Hosted iFrame Tokenizer with your solution to safely handle and tokenize clear PANs without increasing your business' scope of PCI compliance.

CardSecure provides encryption and tokenization services with a secure data vault typically used to store payment card Primary Account Numbers (aka PANs) in a PCI-DSS compliant manner. CardSecure generates a unique and random token value to be used by your application instead of a clear or encrypted PAN, potentially reducing PCI scope considerably.

If your application is using a database with sufficient encryption, CardSecure can tokenize data without additional encryption.

See Understanding CardSecure Tokens for detailed information for working with tokens.

Tokenizing Card-Present Transactions

The CardSecure API supports tokenization of card data captured using an encrypted credit card reader or terminal (for example a CardPointe Desktop or CardPointe Integrated Terminal device).

When a credit card is swiped or inserted at a supported terminal, the extracted encrypted data can be submitted to CardSecure for direct tokenization.

CardSecure does not support passing unencrypted track data. The encrypted data extracted from the device must be produced from a device pre-injected with the required Security Key. If testing is required using non-encrypted track, the data can be tokenized via the CardPointe Gateway (as part of an authorization), or the Personal Account Number (PAN) must be parsed and sent directly with a tokenization request.

CardSecure decrypts the encrypted swipe data and generates a token for the card number. CardSecure also stores the card’s encrypted track data for a short period of time, after which it is discarded.

If the token is used in an authorization request to the CardPointe Gateway during this retention period, the stored track data associated with the token is sent to the processor; this potentially allows the transaction to run as a "card present" transaction. The track data is discarded after the authorization request, and can only be used in a single request.

Encrypting and Tokenizing Payment Account Data

CardSecure allows clients to encrypt the account data (PAN or ACH) sent in a tokenization request using a client-specific RSA public key. CardPointe support can generate a unique RSA key pair, provide the public key (in X.509 format) to you, and retain the private key.

Data must be encrypted using RSA encryption in ECB mode with PKCS1 padding. The encrypted data must be Base64-encoded when sent to CardSecure in a tokenization request.

CardSecure uses the corresponding private key to decrypt the data. The decrypted data is temporarily stored in CardSecure's vault, and the token (generated from the encrypted data) is returned to your application for use in an authorization request to the CardPointe Gateway. Note that the token itself is not encrypted.

Note the following restrictions:

CardSecure only supports encrypted Personal Account Number (PAN) or ACH (eCheck) data. Track data is not supported in an encryption request.
CardSecure encryption is not supported for use with CardPointe Retail Terminal or CardPointe Integrated Terminal devices due to the encryption key already configured within the terminals.

A request to the tokenize endpoint returns a CardSecure token generated from the data provided in the request.

A tokenize request includes payment account data in either the account or devicedata field.

Use the account field to provide a clear or encrypted payment account number (PAN) or ACH account number (in the format <routing>/<account>).

If the account data is encrypted, include the encryptionhandler parameter to instruct CardSecure to decrypt the data using the private key for your site.

Use the devicedata field to provide track data received from a terminal device for an MSR (swipe), EMV (chip), or NFC (contactless) transaction, or a digital wallet payload (for example for a Google Pay transaction).

The tokenize response includes a token generated from the account data. You can then use this token to submit an authorization request to the CardPointe Gateway.
