353 Business::OnlinePayment::InternetSecure is an implementation of
354 L<Business::OnlinePayment> that allows for processing online credit card
355 payments through InternetSecure.
357 See L<Business::OnlinePayment> for more information about the generic
358 Business::OnlinePayment interface.
362 Object creation is done via L<Business::OnlinePayment>; see its manpage for
363 details. The I<merchant_id> processor option is required, and corresponds
364 to the merchant ID assigned to you by InternetSecure.
368 (Other methods are also available -- see L<Business::OnlinePayment> for more
371 =head2 Before order submission
375 =item content( CONTENT )
377 Sets up the data prior to a transaction (overwriting any previous data by the
378 same occasion). CONTENT is an associative array (hash), containing some of
379 the following fields:
383 =item action (required)
385 What to do with the transaction. Only C<Normal Authorization> is supported
390 Transaction type, being one of the following:
398 =item - American Express
404 (This is actually ignored for the moment, and can be left blank or undefined.)
406 =item card_number (required)
408 Credit card number. Spaces are allowed, and will be automatically removed.
410 =item exp_date (required)
412 Credit card expiration date. Since L<Business::OnlinePayment> does not specify
413 any syntax, this module is rather lax regarding what it will accept. The
414 recommended syntax is I<YYYY-MM>, but forms such as I<MM/YYYY> or I<MMYY> are
419 Three- or four-digit verification code printed on the card. This can be left
420 blank or undefined, in which case no check will be performed. Whether or not a
421 transaction will be declined in case of a mismatch depends on the merchant
422 account configuration.
424 This number may be called Card Verification Value (CVV2), Card Validation
425 Code (CVC2) or Card Identification number (CID), depending on the card issuer.
429 A short description of the purchase. See L<"Products list syntax"> for
430 an alternate syntax that allows a list of products to be specified.
432 =item amount (usually required)
434 Total amount to be billed, excluding taxes if they are to be added separately
437 This field is required if B<description> is a string, but should be left
438 undefined if B<description> contains a list of products instead, as outlined
439 in L<"Products list syntax">.
443 Currency of all amounts for this order. This can currently be either
444 C<CAD> (default) or C<USD>.
448 Taxes to be added automatically to B<amount> by InternetSecure.
450 Available taxes are C<GST>, C<PST> and C<HST>. Multiple taxes can specified
451 by concatenating them with spaces, such as C<GST HST>.
453 =item name / company / address / city / state / zip / country / phone / email
455 Customer information. B<Country> should be a two-letter code taken from ISO
462 =head2 After order submission
466 =item receipt_number()
468 Receipt number of this transaction; this is actually a string, unique to all
469 InternetSecure transactions.
473 Sales order number of this transaction. This is a number, unique to each
474 merchant, which is incremented by 1 each time.
478 Date and time of the transaction. Format is C<YYYY/MM/DD hh:mm:ss>.
482 Total amount billed for this order, including taxes.
486 Type of the credit card used for the submitted order, being one of the
495 =item - American Express
501 =item avs_response() / cvv2_response()
503 Results of the AVS and CVV2 checks. See the InternetSecure documentation for
504 the list of possible values.
516 =head2 Products list syntax
518 Optionally, the B<description> field of B<content()> can contain a reference
519 to an array of products, instead of a simple string. Each element of this
520 array represents a different product, and must be a reference to a hash with
521 the following fields:
527 Unit price of this product.
531 Ordered quantity of this product.
535 Internal code for this product.
539 Description of this product
543 Taxes that should be automatically added to this product. If specified, this
544 overrides the B<taxes> field passed to B<content()>.
548 When using a products list, the B<amount> field passed to B<content()> should
552 =head2 Character encoding
554 Since communication to/from InternetSecure is encoded with UTF-8, all Unicode
555 characters are theoretically available when submitting information via
556 B<submit()>. (Further restrictions may be imposed by InternetSecure itself.)
558 When using non-ASCII characters, all data provided to B<submit()> should either
559 be in the current native encoding (typically latin-1, unless it was modified
560 via the C<encoding> pragma), or be decoded via the C<Encode> module.
561 Conversely, all data returned after calling B<submit()> will be automatically
