Card Holder Account Api

A cardholder account models a cardholder and can register 1 or more cards for tokenised charging.

The account offers a credential on file option to the CityPay gateway allowing for both cardholder initiated and merchant initiated transaction processing.

This can include unscheduled or scheduled transactions that can be requested through this API and include batch processing options.

POST/v6/charge

Charge

A charge process obtains an authorisation using a tokenised value which represents a stored card on a card holder account. A card must previously be registered by calling /account-register-card with the card details or retrieved using /account-retrieve

Tokens are generated whenever a previously registered list of cards are retrieved. Each token has, by design a relatively short time to live of 30 minutes. This is both to safe guard the merchant and card holder from replay attacks. Tokens are also restricted to your account, preventing malicious actors from stealing details for use elsewhere.

If a token is reused after it has expired it will be rejected and a new token will be required.

Tokenisation can be used for

  • repeat authorisations on a previously stored card

  • easy authorisations just requiring CSC values to be entered

  • can be used for credential on file style payments

  • can require full 3-D Secure authentication to retain the liability shift

  • wallet style usage

Should an account be used with 3DSv2, the card holder name should also be stored alongside the card as this is a required field with both Visa and MasterCard for risk analysis..
