The goal of this module is to make a machine to machine credit card transactions. CashCow has several options where you can specify URL for handling online payments directly using CGI scripts. So in order to avoid this layer and still perform transactions this module was initiated. At the same time the module attempts to follow the defacto standard for the modules in the Business::OnlinePayment namespace. In order to avoid filtering a HTML response two solutions are doable Either you can specify the result URLs on the CashCow gateway using the PHP located in the php directory, which output XML, which is more structured and more easily parsed. If you want to roll your own , please refer to the examples located in the xml directory. You can also create HTML (or a different XML) output you just need to subclass this class and override the _process_response method. SUPPORTED TRANSACTION TYPES Dankort E-Dankort (**) VISA/Dankort Eurocard MasterCard Visa Visa Electron JCB Diners (*) American Express (*) Forbrugsforeningen (*) Ikano Finans kort (*) (*) To accept this, you need a Merchant Agreement with the card provider in question. (**) Not supported by this module at this time (SEE: TODO). METHODS new This method is located in the SUPER class Business::OnlinePayment and returns a Business::OnlinePayment::CashCow object when called with the string CashCow as parameter to the contructor. submit This method is required to be overloaded by Business::OnlinePayment The method uses HTTPS via Net::SSLeay. set_defaults This method overloads the similar method in Business::OnlinePayment It sets possible defaults required by Business::OnlinePayment::CashCow. test_transaction This method is inherited from Business::OnlinePayment It test the TestFlg form field (SEE: 'Original Formfields', below and 'TODO' below). map_fields This method overloads the similar method in Business::OnlinePayment This method was overloaded for development reasons only and will eventually be removed. remap_fields This method overloads the similar method in Business::OnlinePayment This method was overloaded for development reasons only and will eventually be removed. get_fields This method overloads the similar method in Business::OnlinePayment This method was overloaded for development reasons only and will eventually be removed. content This method is inherited from Business::OnlinePayment is_success This method is inherited from Business::OnlinePayment result_code This method is inherited from Business::OnlinePayment require_avs This method is inherited from Business::OnlinePayment transaction_type This method is inherited from Business::OnlinePayment error_message This method is inherited from Business::OnlinePayment authorization This method is inherited from Business::OnlinePayment server This method is inherited from Business::OnlinePayment port This method is inherited from Business::OnlinePayment path This method is inherited from Business::OnlinePayment _process_response This is a private method implemented to handle the response, which the author recommends to be and XML formatted response. DEVELOPERS NOTES CashCow The CashCow system is quite flexible and therefore it is not possible to say what fields are mandatory and which are optional, since configurations may differ from shop to shop (SEE: TODO). Processor Options * shopid shopid This is the string holding the shopid for the shop configured on the CashCow gateway for the shop you want to access. This field is regarded to be mandatory hence it is needed to complete a transaction - all requests to a CashCow gateway without a shopid is responded to with an HTTP response code of 304. Original CashCow Formfields These fields are the ones provided by the CashCow gateway. This module complies with the Business::OnlinePayment API v2. so the API described in this module should be used. But fields listed below can be added to the content dataset (SEE: SYNOPSIS) if some extra information is needed - use of some fields however is not recommended since these are redundant with the fields specified in the Business::OnlinePayment API. * foreignorderid * sessionid * cust_name * cust_street * cust_zip * cust_phone * cust_email * cardnum * emonth * eyear * cvc * amount * currency foreignorderid This field can be use to hold your own orderid for reference. This field is regarded as defaulting to optional. Can be used freely. sessionid This field can be use to hold a sessionid. This field is regarded as defaulting to optional. Can be used freely. cust_name The customer name (full name) - concatenation might be necessary. Cardholders name should go in this field. This field is regarded as defaulting to optional. Please use: name instead. cust_street The street of the customer address. This field is regarded as defaulting to optional. Please use: address instead. cust_zip The zip code of the customers address. This field is regarded as defaulting to optional. Please use: zip instead. cust_phone The phonenumber of the customer. This field is regarded as defaulting to optional. Please use: phone instead. cust_email This is the customer email adresse. CashCow has some different options for this parameter. It can either be optional or mandatory and you can even have the CashCow gateway evaluate the email address with the configuration parameter strict which can be set on the gateway. This field is regarded as defaulting to optional. Please use: email instead. cardnum This field is regarded as defaulting to mandatory. Please use: card_number instead. emonth The expiration month in two digits, listed on the front of the creditcard. This field is regarded as defaulting to mandatory. Please use: expiration instead. eyear The expiration year in two digits, listed on the front of the creditcard. This field is regarded as defaulting to mandatory. Please use: expiration instead. cvc The 3- or 4-digit control number on the back of a creditcard. The CashCow gateway refers to this as CVC, but the name actually depends on the card in question, but this module sticks to the name CVC eventhough it might be used for: * CVV2 (Visa) * CVC2 (Mastercard) * CID (American Express) This field is regarded as defaulting to mandatory. amount The amount should be provided in english notation, do not use locale if it differs from the using . (dot) as separator. (SEE: SYNOPSIS). This field is regarded as defaulting to mandatory. currency This argument can be used to specify the currency. The currency defaults to 208, which is the numeric currency code for DKK - Danish Krone. The numeric codes are defined in: ISO4217 See, SEE ALSO section for references. TODO * Implement handling of e-dankort card type * Implement handling of ecredit transactions (default is PBS) * Implement handling of subscribtions * Investigate return values and use of: authorization() and result_code() * Investigate test flags (TestFlg) * Make it possible to control what fields are mandatory and optional. This could be done via the optional processor info parameter to the constructor (SEE: new). * The tests reveal a warning of sorts from Net::SSLeay - it would be nice to have this warning eliminated. * Some warnings are issued due to redefinition of autoloaded subs built by the SUPER class, this would be nice to get out of the way aswell t/Submit..........ok 1/6Subroutine shopid redefined at (eval 36) line 1. Subroutine testflg redefined at (eval 37) line 1.
