WebService::PayPal::PaymentsAdvanced - A simple wrapper around the PayPal Payments Advanced web service

=head1 VERSION

version 0.000027

=head1 SYNOPSIS

    use WebService::PayPal::PaymentsAdvanced;
    my $payments = WebService::PayPal::PaymentsAdvanced->new(
        {
            password => 'seekrit',
            user     => 'username',
            vendor   => 'somevendor',
        }
    );

        {
            AMT            => 100,
            TRXTYPE        => 'S',
            BILLINGTYPE    => 'MerchantInitiatedBilling',
            CANCELURL      => 'https://example.com/cancel',
            ERRORURL       => 'https://example.com/error',

            NAME           => 'Chuck Norris',
            RETURNURL      => 'https://example.com/return',
        }
    );

    my $uri = $response->hosted_form_uri;

    # Store token data for later use.  You'll need to implement this yourself.
    $foo->freeze_token_data(
        token    => $response->secure_token,

        ip_address => $ip,
        params     => $params,
    );

    # Fetch the tokens from the original request. You'll need to implement

=head1 DESCRIPTION

BETA BETA BETA.  The interface is still subject to change.

This is a wrapper around the "PayPal Payments Advanced" (AKA "PayPal Payflow
Link") hosted forms.  This code does things like facilitating secure token
creation, providing an URL which you can use to insert an hosted_form into
your pages and processing the various kinds of response you can get from
PayPal.

We also use various exception classes to make it easier for you to decide how
to handle the parts that go wrong.

=head1 OBJECT INSTANTIATION

The following parameters can be supplied to C<new()> when creating a new object.

=head2 Required Parameters

=head3 password

The value of the C<password> field you use when logging in to the Payflow
Manager.  (You'll probably want to create a specific user just for API calls).

=head3 user

The value of the C<user> field you use when logging in to the Payflow Manager.

=head3 vendor

The value of the C<vendor> field you use when logging in to the Payflow
Manager.

=head2 Optional Parameters

=head3 nonfatal_result_codes

An arrayref of result codes that will be treated as non-fatal (i.e., that will
not cause an exception). By default, only 0 is considered non-fatal, but
depending on your integration, other codes such as 112 (failed AVS check) may
be considered non-fatal.

=head3 partner

The value of the C<partner> field you use when logging in to the Payflow
Manager. Defaults to C<PayPal>.

=head3 payflow_pro_uri

The hostname for the Payflow Pro API.  This is where token creation requests
get directed.  This already has a sensible (and correct) default, but it is
settable so that you can more easily mock API calls when testing.

=head3 payflow_link_uri

The hostname for the Payflow Link website.  This is the hosted service where
users will enter their payment information.  This already has a sensible (and
correct) default, but it is settable in case you want to mock it while testing.

=head3 production_mode

This is a C<Boolean>.  Set this to C<true> if when you are ready to process
real transactions.  Defaults to C<false>.

=head3 ua

You may provide your own UserAgent, but it must be of the L<LWP::UserAgent>
family.  If you do provide a UserAgent, be sure to set a sensible timeout
value. Requests to the web service frequently run 20-30 seconds.

This can be useful for debugging.  You'll be able to get detailed information
about the network calls which are being made.

    use LWP::ConsoleLogger::Easy qw( debug_ua );
    use LWP::UserAgent;
    use WebService::PayPal::PaymentsAdvanced;

    my $ua = LWP::UserAgent;
    debug_ua($ua);

    my $payments
        = WebService::PayPal::PaymentsAdvanced->new( ua => $ua, ... );

    # Now fire up a console and watch your network activity.

Check the tests which accompany this distribution for an example of how to mock
API calls using L<Test::LWP::UserAgent>.

=head3 validate_hosted_form_uri

C<Boolean>.  If enabled, this module will attempt to GET the uri which you'll
be providing to the end user.  This can help you identify issues on the PayPal
side.  This is helpful because you'll be able to log exceptions thrown by this
method and deal with them accordingly.  If you disable this option, you'll need
to rely on end users to report issues which may exist within PayPal's hosted
pages.  Defaults to C<true>.

=head3 verbose

C<Boolean>.  Sets C<VERBOSITY=HIGH> on all transactions if enabled.  Defaults
to C<true>.

=head2 Methods

=head3 create_secure_token

Create a secure token which you can use to create a hosted form uri.  Returns a
L<WebService::PayPal::PaymentsAdvanced::Response::SecureToken> object.

The first parameter holds the key/value parameters for the request. The second
parameter is optional and holds parameters to the underlying
L<WebService::PayPal::PaymentsAdvanced::Response::SecureToken> object, which is
useful to set attributes such as C<retry_attempts> and C<retry_callback>.

    use WebService::PayPal::PaymentsAdvanced;
    my $payments = WebService::PayPal::PaymentsAdvanced->new(...);

    my $response = $payments->create_secure_token(
        {
            AMT            => 100,
            TRXTYPE        => 'S',
            BILLINGTYPE    => 'MerchantInitiatedBilling',
            CANCELURL      => 'https://example.com/cancel',
            ERRORURL       => 'https://example.com/error',
            L_BILLINGTYPE0 => 'MerchantInitiatedBilling',
            NAME           => 'Chuck Norris',
            RETURNURL      => 'https://example.com/return'
        }
    );

    print $response->secure_token;

=head3 get_response_from_redirect

This method can be used to parse responses from PayPal to your return URL.
It's essentially a wrapper around
L<WebService::PayPal::PaymentsAdvanced::Response::FromRedirect>.  Returns a
L<WebService::PayPal::PaymentsAdvanced::Response> object.

    my $response = $payments->get_response_from_redirect(
        params     => $params,
    );
    print $response->message;

=head3 get_response_from_silent_post

This method can be used to validate responses from PayPal to your silent POST
url.  If you provide an ip_address parameter, it will be validated against a
list of known IPs which PayPal provides.  You're encouraged to provide an IP
address in order to prevent spoofing of payment responses.  See
L<WebService::PayPal::PaymentsAdvanced::Response::FromSilentPOST> for more
information on this behaviour.

This method returns a
L<WebService::PayPal::PaymentsAdvanced::Response::FromSilentPost::PayPal>
object for PayPal transactions.  It returns a
L<WebService::PayPal::PaymentsAdvanced::Response::FromSilentPost::CreditCard>
object for credit card transactions.  You can either inspect the class returned
to you or use the C<is_credit_card_transaction> or C<is_paypal_transaction>
methods to learn which method the customer paid with.  Both methods return a
C<Boolean>.

    my $response = $payments->get_response_from_redirect(
        ip_address => $ip,
        params     => $params,
    );
    print $response->message. "\n";
    if ( $response->is_credit_card_transaction ) {
        print $response->card_type, q{ }, $response->card_expiration;
    }

=head3 post

Generic method to post arbitrary params to PayPal.  Requires a C<HashRef> of
parameters and returns a L<WebService::PayPal::PaymentsAdvanced::Response>
object.  Any lower case keys will be converted to upper case before this
response is sent. The second parameter is an optional C<HashRef>. If provided,
it defines attributes to pass to the
L<WebService::PayPal::PaymentsAdvanced::Response::SecureToken> object.

    use WebService::PayPal::PaymentsAdvanced;
    my $payments = WebService::PayPal::PaymentsAdvanced->new(...);

    my $response = $payments->post( { TRXTYPE => 'V', ORIGID => $pnref, } );
    say $response->message;
