347 Business::OnlinePayment::InternetSecure is an implementation of
348 L<Business::OnlinePayment> that allows for processing online credit card
349 payments through InternetSecure.
351 See L<Business::OnlinePayment> for more information about the generic
352 Business::OnlinePayment interface.
356 Object creation is done via L<Business::OnlinePayment>; see its manpage for
357 details. The I<merchant_id> processor option is required, and corresponds
358 to the merchant ID assigned to you by InternetSecure.
362 (Other methods are also available -- see L<Business::OnlinePayment> for more
365 =head2 Before order submission
369 =item content( CONTENT )
371 Sets up the data prior to a transaction (overwriting any previous data by the
372 same occasion). CONTENT is an associative array (hash), containing some of
373 the following fields:
377 =item action (required)
379 What to do with the transaction. Only C<Normal Authorization> is supported
384 Transaction type, being one of the following:
392 =item - American Express
398 (This is actually ignored for the moment, and can be left blank or undefined.)
400 =item card_number (required)
402 Credit card number. Spaces are allowed, and will be automatically removed.
404 =item exp_date (required)
406 Credit card expiration date. Since L<Business::OnlinePayment> does not specify
407 any syntax, this module is rather lax regarding what it will accept. The
408 recommended syntax is I<YYYY-MM>, but forms such as I<MM/YYYY> or I<MMYY> are
413 Three- or four-digit verification code printed on the card. This can be left
414 blank or undefined, in which case no check will be performed. Whether or not a
415 transaction will be declined in case of a mismatch depends on the merchant
416 account configuration.
418 This number may be called Card Verification Value (CVV2), Card Validation
419 Code (CVC2) or Card Identification number (CID), depending on the card issuer.
423 A short description of the purchase. See L<"Products list syntax"> for
424 an alternate syntax that allows a list of products to be specified.
426 =item amount (usually required)
428 Total amount to be billed, excluding taxes if they are to be added separately
431 This field is required if B<description> is a string, but should be left
432 undefined if B<description> contains a list of products instead, as outlined
433 in L<"Products list syntax">.
437 Currency of all amounts for this order. This can currently be either
438 C<CAD> (default) or C<USD>.
442 Taxes to be added automatically to B<amount> by InternetSecure.
444 Available taxes are C<GST>, C<PST> and C<HST>. Multiple taxes can specified
445 by concatenating them with spaces, such as C<GST HST>.
447 =item name / company / address / city / state / zip / country / phone / email
449 Customer information. B<Country> should be a two-letter code taken from ISO
456 =head2 After order submission
460 =item receipt_number()
462 Receipt number of this transaction; this is actually a string, unique to all
463 InternetSecure transactions.
467 Sales order number of this transaction. This is a number, unique to each
468 merchant, which is incremented by 1 each time.
472 Date and time of the transaction. Format is C<YYYY/MM/DD hh:mm:ss>.
476 Total amount billed for this order, including taxes.
480 Cardholder's name. This is currently a mere copy of the B<name> field passed
485 Type of the credit card used for the submitted order, being one of the
494 =item - American Express
500 =item avs_response() / cvv2_response()
502 Results of the AVS and CVV2 checks. See the InternetSecure documentation for
503 the list of possible values.
515 =head2 Products list syntax
517 Optionally, the B<description> field of B<content()> can contain a reference
518 to an array of products, instead of a simple string. Each element of this
519 array represents a different product, and must be a reference to a hash with
520 the following fields:
526 Unit price of this product.
530 Ordered quantity of this product.
534 Internal code for this product.
538 Description of this product
542 Taxes that should be automatically added to this product. If specified, this
543 overrides the B<taxes> field passed to B<content()>.
547 When using a products list, the B<amount> field passed to B<content()> should
551 =head2 Character encoding
553 Since communication to/from InternetSecure is encoded with UTF-8, all Unicode
554 characters are theoretically available when submitting information via
555 B<submit()>. (Further restrictions may be imposed by InternetSecure itself.)
557 When using non-ASCII characters, all data provided to B<submit()> should either
558 be in the current native encoding (typically latin-1, unless it was modified
559 via the C<encoding> pragma), or be decoded via the C<Encode> module.
560 Conversely, all data returned after calling B<submit()> will be automatically
