345 Business::OnlinePayment::InternetSecure is an implementation of
346 L<Business::OnlinePayment> that allows for processing online credit card
347 payments through InternetSecure.
349 See L<Business::OnlinePayment> for more information about the generic
350 Business::OnlinePayment interface.
354 Object creation is done via L<Business::OnlinePayment>; see its manpage for
355 details. The I<merchant_id> processor option is required, and corresponds
356 to the merchant ID assigned to you by InternetSecure.
360 (Other methods are also available -- see L<Business::OnlinePayment> for more
363 =head2 Before order submission
367 =item content( CONTENT )
369 Sets up the data prior to a transaction (overwriting any previous data by the
370 same occasion). CONTENT is an associative array (hash), containing some of
371 the following fields:
375 =item action (required)
377 What to do with the transaction. Only C<Normal Authorization> is supported
382 Transaction type, being one of the following:
390 =item - American Express
396 (This is actually ignored for the moment, and can be left blank or undefined.)
398 =item card_number (required)
400 Credit card number. Spaces are allowed, and will be automatically removed.
402 =item exp_date (required)
404 Credit card expiration date. Since L<Business::OnlinePayment> does not specify
405 any syntax, this module is rather lax regarding what it will accept. The
406 recommended syntax is I<YYYY-MM>, but forms such as I<MM/YYYY> or I<MMYY> are
411 Three- or four-digit verification code printed on the card. This can be left
412 blank or undefined, in which case no check will be performed. Whether or not a
413 transaction will be declined in case of a mismatch depends on the merchant
414 account configuration.
416 This number may be called Card Verification Value (CVV2), Card Validation
417 Code (CVC2) or Card Identification number (CID), depending on the card issuer.
421 A short description of the purchase. See L<"Products list syntax"> for
422 an alternate syntax that allows a list of products to be specified.
424 =item amount (usually required)
426 Total amount to be billed, excluding taxes if they are to be added separately
429 This field is required if B<description> is a string, but should be left
430 undefined if B<description> contains a list of products instead, as outlined
431 in L<"Products list syntax">.
435 Currency of all amounts for this order. This can currently be either
436 C<CAD> (default) or C<USD>.
440 Taxes to be added automatically to B<amount> by InternetSecure.
442 Available taxes are C<GST>, C<PST> and C<HST>. Multiple taxes can specified
443 by concatenating them with spaces, such as C<GST HST>.
445 =item name / company / address / city / state / zip / country / phone / email
447 Customer information. B<Country> should be a two-letter code taken from ISO
454 =head2 After order submission
458 =item receipt_number()
460 Receipt number of this transaction; this is actually a string, unique to all
461 InternetSecure transactions.
465 Sales order number of this transaction. This is a number, unique to each
466 merchant, which is incremented by 1 each time.
470 Date and time of the transaction. Format is C<YYYY/MM/DD hh:mm:ss>.
474 Total amount billed for this order, including taxes.
478 Cardholder's name. This is currently a mere copy of the B<name> field passed
483 Type of the credit card used for the submitted order, being one of the
492 =item - American Express
498 =item avs_response() / cvv2_response()
500 Results of the AVS and CVV2 checks. See the InternetSecure documentation for
501 the list of possible values.
513 =head2 Products list syntax
515 Optionally, the B<description> field of B<content()> can contain a reference
516 to an array of products, instead of a simple string. Each element of this
517 array represents a different product, and must be a reference to a hash with
518 the following fields:
524 Unit price of this product.
528 Ordered quantity of this product.
532 Internal code for this product.
536 Description of this product
540 Taxes that should be automatically added to this product. If specified, this
541 overrides the B<taxes> field passed to B<content()>.
545 When using a products list, the B<amount> field passed to B<content()> should
549 =head2 Character encoding
551 Since communication to/from InternetSecure is encoded with UTF-8, all Unicode
552 characters are theoretically available when submitting information via
553 B<submit()>. (Further restrictions may be imposed by InternetSecure itself.)
555 When using non-ASCII characters, all data provided to B<submit()> should either
556 be in the current native encoding (typically latin-1, unless it was modified
557 via the C<encoding> pragma), or be decoded via the C<Encode> module.
558 Conversely, all data returned after calling B<submit()> will be automatically
