VALID_PHONE_FORMAT =

Wirecard only allows phone numbers with a format like this: +xxx(yyy)zzz-zzzz-ppp, where:

xxx = Country code
yyy = Area or city code
zzz-zzzz = Local number
ppp = PBX extension

For example, a typical U.S. or Canadian number would be “+1(202)555-1234-739” indicating PBX extension 739 at phone number 5551234 within area code 202 (country code 1).

Instance Method Details

#authorize(money, payment_method, options = {}) ⇒ Object

Authorization - the second parameter may be a CreditCard or a String which represents a GuWID reference to an earlier transaction. If a GuWID is given, rather than a CreditCard, then then the :recurring option will be forced to “Repeated”

#store(creditcard, options = {}) ⇒ Object

Store card - Wirecard supports the notion of “Recurring Transactions” by allowing the merchant to provide a reference to an earlier transaction (the GuWID) rather than a credit card. A reusable reference (GuWID) can be obtained by sending a purchase or authorization transaction with the element “RECURRING_TRANSACTION/Type” set to “Initial”. Subsequent transactions can then use the GuWID in place of a credit card by setting “RECURRING_TRANSACTION/Type” to “Repeated”.

This implementation of card store utilizes a Wirecard “Authorization Check” (a Preauthorization that is automatically reversed). It defaults to a check amount of “100” (i.e. $1.00) but this can be overriden (see below).

IMPORTANT: In order to reuse the stored reference, the authorization from the response should be saved by your application code.

Options specific to store

  • :amount – The amount, in cents, that should be “validated” by the Authorization Check. This amount will be reserved and then reversed. Default is 100.

Note: This is not the only way to achieve a card store operation at Wirecard. Any purchase or authorize can be sent with options = ‘Initial’ to make the returned authorization/GuWID usable in later transactions with options = ‘Repeated’.
