CardSecure API

The following entries describe changes to the CardSecure API and documentation.

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"
}

Date Updated: 8/12/2019

This release includes the following updates:

Support for CVV and Expiry

CardSecure now supports tokenizing the CVV and Expiry values for payment cards.

The CVV and Expiry values are stored in the token until the token is used in an authorization attempt, after which this information is cleared from the token.

The tokenize request now supports the following optional parameters:

FieldContentMax LengthDescription
cvvCard Verification Value4

Optional, the card verification value (CVV).

Must be a 3 or 4 character numeric string.

Alphanumeric and special characters are not supported.

Strings greater than 4 characters or fewer than 3 characters are not supported.

expiryCard Expiration8

Optional, the card expiration date.

Must be a numeric string.

Must be formatted as

  • MMYY
  • YYYYMM
  • YYYYMMDD

Support for Google Pay

CardSecure now supports tokenizing Google Pay wallet account data. 

To tokenize a Google Pay account, use the devicedata parameter to pass the Google Pay data, and use the encryptionhandler parameter to pass the value "EC_GOOGLE_PAY" to allow CardSecure to decrypt and handle the encrypted payload.

See the tokenize request description for more information and an example. 

See the Google Pay Developer Guide for detailed information on integrating Google Pay acceptance with a mobile app.
