356 Business::OnlinePayment::InternetSecure is an implementation of
357 L<Business::OnlinePayment> that allows for processing online credit card
358 payments through InternetSecure.
360 See L<Business::OnlinePayment> for more information about the generic
361 Business::OnlinePayment interface.
365 Object creation is done via L<Business::OnlinePayment>; see its manpage for
366 details. The I<merchant_id> processor option is required, and corresponds
367 to the merchant ID assigned to you by InternetSecure.
371 (Other methods are also available -- see L<Business::OnlinePayment> for more
374 =head2 Before order submission
378 =item content( CONTENT )
380 Sets up the data prior to a transaction (overwriting any previous data by the
381 same occasion). CONTENT is an associative array (hash), containing some of
382 the following fields:
386 =item action (required)
388 What to do with the transaction. Only C<Normal Authorization> is supported
393 Transaction type, being one of the following:
401 =item - American Express
407 (This is actually ignored for the moment, and can be left blank or undefined.)
409 =item card_number (required)
411 Credit card number. Spaces are allowed, and will be automatically removed.
413 =item exp_date (required)
415 Credit card expiration date. Since L<Business::OnlinePayment> does not specify
416 any syntax, this module is rather lax regarding what it will accept. The
417 recommended syntax is I<YYYY-MM>, but forms such as I<MM/YYYY> or I<MMYY> are
422 Three- or four-digit verification code printed on the card. This can be left
423 blank or undefined, in which case no check will be performed. Whether or not a
424 transaction will be declined in case of a mismatch depends on the merchant
425 account configuration.
427 This number may be called Card Verification Value (CVV2), Card Validation
428 Code (CVC2) or Card Identification number (CID), depending on the card issuer.
432 A short description of the purchase. See L<"Products list syntax"> for
433 an alternate syntax that allows a list of products to be specified.
435 =item amount (usually required)
437 Total amount to be billed, excluding taxes if they are to be added separately
440 This field is required if B<description> is a string, but should be left
441 undefined if B<description> contains a list of products instead, as outlined
442 in L<"Products list syntax">.
446 Currency of all amounts for this order. This can currently be either
447 C<CAD> (default) or C<USD>.
451 Taxes to be added automatically to B<amount> by InternetSecure.
453 Available taxes are C<GST>, C<PST> and C<HST>. Multiple taxes can specified
454 by concatenating them with spaces, such as C<GST HST>.
456 =item name / company / address / city / state / zip / country / phone / email
458 Customer information. B<Country> should be a two-letter code taken from ISO
465 =head2 After order submission
469 =item receipt_number()
471 Receipt number of this transaction; this is actually a string, unique to all
472 InternetSecure transactions.
476 Sales order number of this transaction. This is a number, unique to each
477 merchant, which is incremented by 1 each time.
481 Date and time of the transaction. Format is C<YYYY/MM/DD hh:mm:ss>.
485 Total amount billed for this order, including taxes.
489 Type of the credit card used for the submitted order, being one of the
498 =item - American Express
504 =item avs_response() / cvv2_response()
506 Results of the AVS and CVV2 checks. See the InternetSecure documentation for
507 the list of possible values.
519 =head2 Products list syntax
521 Optionally, the B<description> field of B<content()> can contain a reference
522 to an array of products, instead of a simple string. Each element of this
523 array represents a different product, and must be a reference to a hash with
524 the following fields:
530 Unit price of this product.
534 Ordered quantity of this product.
538 Internal code for this product.
542 Description of this product
546 Taxes that should be automatically added to this product. If specified, this
547 overrides the B<taxes> field passed to B<content()>.
551 When using a products list, the B<amount> field passed to B<content()> should
555 =head2 Character encoding
557 Since communication to/from InternetSecure is encoded with UTF-8, all Unicode
558 characters are theoretically available when submitting information via
559 B<submit()>. (Further restrictions may be imposed by InternetSecure itself.)
561 When using non-ASCII characters, all data provided to B<submit()> should either
562 be in the current native encoding (typically latin-1, unless it was modified
563 via the C<encoding> pragma), or be decoded via the C<Encode> module.
564 Conversely, all data returned after calling B<submit()> will be automatically
