=head1 SUPPORTED TRANSACTION TYPES

=head2 CC, Visa, MasterCard, American Express, Discover

Content required: type, login, password|transaction_key, action, amount, first_name, last_name, card_number, expiration.

=head2 Check

Content required: type, login, password|transaction_key, action, amount, first_name, last_name, account_number, routing_code, bank_name.

=head1 DESCRIPTION

For detailed information see L<Business::OnlinePayment>.

=head1 NOTE

Unlike Business::OnlinePayment or pre-3.0 verisons of
Business::OnlinePayment::AuthorizeNet, 3.1 requires separate first_name and
last_name fields.

Business::OnlinePayment::AuthorizeNet uses Authorize.Net's "Advanced
Integration Method (AIM) (formerly known as ADC direct response)", sending a
username and transaction_key or password with every transaction.  Therefore, Authorize.Net's
referrer "security" is not necessary.  In your Authorize.Net interface at
https://secure.authorize.net/ make sure the list of allowable referers is
blank.  Alternatively, set the B<referer> field in the transaction content.

To settle an authorization-only transaction (where you set action to
'Authorization Only'), submit the nine-digit transaction id code in
the field "order_number" with the action set to "Post Authorization".
You can get the transaction id from the authorization by calling the
order_number method on the object returned from the authorization.
You must also submit the amount field with a value less than or equal
to the amount specified in the original authorization.

Recently (February 2002), Authorize.Net has turned address
verification on by default for all merchants.  If you do not have
valid address information for your customer (such as in an IVR
application), you must disable address verification in the Merchant
Menu page at https://secure.authorize.net/ so that the transactions
aren't denied due to a lack of address information.

=head1 COMPATIBILITY

This module implements Authorize.Net's API verison 3.1 using the Advanced
Integration Method (AIM), formerly known as ADC Direct Response.  See
http://www.authorize.net/support/AIM_guide.pdf for details.
