160 Business::OnlinePayment is a generic module for processing payments through
161 online credit card processors, electronic cash systems, etc.
163 =head1 METHODS AND FUNCTIONS
165 =head2 new($processor, %processor_options);
167 Create a new Business::OnlinePayment object, $processor is required, and defines the online processor to use. If necessary, processor options can be specified, currently supported options are 'Server', 'Port', and 'Path', which specify how to find the online processor (https://server:port/path), but individual processor modules should supply reasonable defaults for this information, override the defaults only if absolutely necessary (especially path), as the processor module was probably written with a specific target script in mind.
169 =head2 content(%content);
171 The information necessary for the transaction, this tends to vary a little depending on the processor, so we have chosen to use a system which defines specific fields in the frontend which get mapped to the correct fields in the backend. The currently defined fields are:
177 Transaction type, supported types are:
178 Visa, MasterCard, American Express, Discover, Check (not all processors support all these transaction types).
182 Your login name to use for authentication to the online processor.
186 Your password to use for authentication to the online processor.
190 What to do with the transaction (currently available are: Normal Authorization, Authorization Only, Credit, Post Authorization)
194 A description of the transaction (used by some processors to send information to the client, normally not a required field).
198 The amount of the transaction, most processors dont want dollar signs and the like, just a floating point number.
200 =item * invoice_number
202 An invoice number, for your use and not normally required, many processors require this field to be a numeric only field.
206 A customer identifier, again not normally required.
210 The customers name, your processor may not require this.
214 The customers address (your processor may not require this unless you are requiring AVS Verification).
218 The customers city (your processor may not require this unless you are requiring AVS Verification).
222 The customers state (your processor may not require this unless you are requiring AVS Verification).
226 The customers zip code (your processor may not require this unless you are requiring AVS Verification).
234 Customer's phone number.
238 Customer's fax number.
242 Customer's email address.
246 Credit card number (obviously not required for non-credit card transactions).
250 Credit card expiration (obviously not required for non-credit card transactions).
252 =item * account_number
254 Bank account number for electronic checks or electronic funds transfer.
258 Bank's routing code for electronic checks or electronic funds transfer.
262 Bank's name for electronic checks or electronic funds transfer.
268 Submit the transaction to the processor for completion
272 Returns true if the transaction was submitted successfully, false if it failed (or undef if it has not been submitted yet).
274 =head2 result_code();
276 Returns the precise result code that the processor returned, these are normally one letter codes that don't mean much unless you understand the protocol they speak, you probably don't need this, but it's there just in case.
278 =head2 test_transaction();
280 Most processors provide a test mode, where submitted transactions will not actually be charged or added to your batch, calling this function with a true argument will turn that mode on if the processor supports it, or generate a fatal error if the processor does not support a test mode (which is probably better than accidentally making real charges).
282 =head2 require_avs();
284 Providing a true argument to this module will turn on address verification (if the processor supports it).
286 =head2 transaction_type();
288 Retrieve the transaction type (the 'type' argument to contents();). Generally only used internally, but provided in case it is useful.
290 =head2 error_message();
292 If the transaction has been submitted but was not accepted, this function will return the provided error message (if any) that the processor returned.
294 =head2 authorization();
296 If the transaction has been submitted and accepted, this function will provide you with the authorization code that the processor returned.
300 Retrieve or change the processor submission server address (CHANGE AT YOUR OWN RISK).
304 Retrieve or change the processor submission port (CHANGE AT YOUR OWN RISK).
308 Retrieve or change the processor submission path (CHANGE AT YOUR OWN RISK).
