=head1 NAME

Business::OnlinePayment::Exact - Perl extension for doing credit card 
processing through the E-xact v7 Web Services API payment gateway.

=head1 SYNOPSIS

  use Business::OnlinePayment;
  my $tx = new Business::OnlinePayment('Exact');
  $tx->content(
    amount => '19.00',
    card_number => '4200000000000000',
    expiration => '0110',
    name => 'Some Guy',
    action => 'authorization only',
    login => 'A000XX-XX'
    password => 'password'
  );
  $tx->submit;
  if ($tx->is_success()) {
    my $ordernum = $tx->order_number;
    print "Got the cash";
  }
  else {
    print $tx->error_message;
  }

=head1 ABSTRACT

    This is a Business::OnlinePayment module for E-xact loosely based on
    Business::OnlinePayment::AuthorizeNet.  I've only used it for normal
    authorization so it may require some work to do pre auth, etc.


=head1 DESCRIPTION

    See synopsis.  It works like any other Business::OnlinePayment module.
    The following content keys are usefull:
    login
    password
    amount
    card_number
    expiration
    name
    referer
    email
    address
    order_number
    customer_ip
    action

    The following content keys are also available (but not really usefull):
    'first_name' and 'last_name' will combine to override 'name'
    'expiration_month' and 'expiration_year' will combine to override 
    'expiration'

    The 'authorization' method will return the bank authorization code, and the
    'order_number' method will contain the sequence number from E-xact.
    The content key 'referer' can be used to store any string data (20 bytes)
    and used to search for those transactions from the web interface.

=head2 EXPORT

None by default.
