Storing credentials for future CIT / Store a card only

Setup a customerAgreement to store credentials for future CIT payments.

  • Set the customerAgreement.type to cardOnFile and storedCardUsage to first
  • Set tokenCreation.type to worldpay in order to store the credentials.
  • The example includes 3DS for SCA or 3DS mandated countries
  • If no initial payment is to be made (e.g. free trial), set the value.amount to 0. A card verification is performed instead.
