DESCRIPTION ^

This module interfaces Business::OnlinePayment with Ogone, a European Payment Provider. It is based on the Ogone DirectLink API.

Ogone accepted credit cards: American Express, MasterCard, VISA, AIRPLUS, Aurore, Billy, Cofinoga, Diners Club, JCB, Laser, Privilège, Solo, MaestroUK, UATP

Features

PROGRAM FLOW ^

You have a choice when implementing credit card processing. You can pocess the money transfer in one or more steps. If you choose to go with one step, customers will be billed directly.

action => 'Normal Authorization' (with operation => 'SAL' (default))
action => 'Authorization Only' (with operation => 'RES' (default)) then action => 'Post Authorization' (with operation => 'SAS' (default))

METHODS ^

new()

Not used directly. Creates a new instance. It's possible to pass credential infomation in the constructor.

    my $tx = new Business::OnlinePayment('Ogone', pspid => 'fred', login => 'bedrock_api', password => 'fl1nst0ne');

content()

This method takes a lot of parameters to prepare the transaction to be submitted. Depending on these parameters the payment processor will act on them in different ways, you can consider it a sort of dispatch table. The main actors are action, alias, win3ds.

content() required parameters

Depending on what action you are triggering a number of parameters are required. You can use the following pseudo perl code as a reference to what exactly is required depending on the parameters.

    my @args_basic  = qw/login password PSPID action/;
    my @args_ccard  = qw/card_number expiration cvc/;
    my @args_alias  = qw/alias cvc/;
    my @args_recur  = (@args_basic, qw/name subscription_id subscription_orderid invoice_number amount currency startdate enddate period_unit period_moment period_number/, has_cc_number() ? @args_ccard : @args_alias ), 
    my @args_new    = @args_basic, qw/invoice_number amount currency/, has_cc_number() ? @args_ccard : @args_alias;
    my @args_post   = @args_basic, qw/invoice_number/;
    my @query       = @args_basic, qw/invoice_number/;

    for ($action) {
        qr/authorization only/i      => required_arguments( @args_new ),
        qr/normal authorization/i    => required_arguments( @args_new ),
        qr/post authorization/i      => required_arguments( @args_post ),
        qr/query/i                   => required_arguments( @query ),
    }

content() examples

example authorize only request: requests a claim on an amount of money [RES] (and creates an alias)

    my %auth = ( pspid => 'fred', login => 'bedrock_api', password => 'fl1nst0ne' );

    my $id = $session->get('orderid');
    my $res = new Business::OnlinePayment('Ogone', %auth);

    $res->content( invoice_number => $id, action => 'authorize only', alias => 'wilma flinstone',  ... );
    $res->submit();

    if ( $res->is_success() ) {
        $dbh->do('insert into tx_status_log (id,status) values (?,?)',undef,$id,"RES OK");
    };

example post authorization request: transfers an amount of money [SAL].

    my $sal = new Business::OnlinePayment('Ogone', %auth);

    $sal->content( invoice_number => $is, action => 'post authorization', ...);
    $res->submit();

    if ( $res->is_success() ) {
        $dbh->do('insert into tx_status_log (id,status) values (?,?)',undef,$id,"SAL OK");
    };

example with alias (ie: no card number used)

    my $res = new Business::OnlinePayment('Ogone',%auth);

    $res->content(alias => 'wilma_flinstone', cvc => 123, ...);
    $res->submit();

    if ( $res->is_success() ) {
        $dbh->do('insert into tx_status_log (id,status) values (?,?)',undef,$id,"RES OK");
    };

example with recurrent transaction using an alias

    my $res = new Business::OnlinePayment('Ogone',%auth);
    
    $res->content(  action => 'recurrent authorization',
                    alias => 'wilma_finstone',
                    name => 'Wilma Flinstone', 
                    cvc => '423',
                    amount => '42',
                    description => "monthly subscription to bedrock magazine",
                    subscription_id => 12312312
                    invoice_number => 9123,
                    subscription_orderid => 123112,
                    startdate => '2012-01-01',
                    enddate => '2013-01-01',
                    status => 1,
                    period_unit => 'm',
                    period_moment => 1,
                    period_number => 1,
                    ... );

    $res->submit();
);

      6                                     STATUS=8 .<-----------'
1 We want to refund a transaction. To check the transaction is refundable, we must first query it.
2 Refunds are only possible once a transaction is completed (STATUS = 9) (e.g. not while it is processing = 91), thus loop until so.
3 Request refund using orderID or PAYID and PAYISUB to identify refundable operation.
4 STATUS=81 indicates the refund is being processed
5 Ogone handles processing with your bank
6 Money has been taken from your account. STATUS is set to 8

TODO ^

TESTING ^

To test this module you will need to set your credentials in the environment. Put the following in a file in your hoe directory e.g. ~/.ogone The password is not the same as the PSPID password, you will need to enter the API users' password.

    export OGONE_PSPID=bob
    export OGONE_USERID=bob_api
    export OGONE_PSWD=foobar

Limit access to the ~/.ogone file

    chmod 600 ~/.ogone

Then load this file into your env en perform the testcases:

    source ~/.ogone
    perl -I lib/ t/*.t

Bugs, inacuracies and quircks

Security risk: password encryption

Ogone claims to encrypt your password where in fact in only hashes it using the SHA-1 algorithm. I suppose someone else wrote the accompanying texts, because the url states hash_pwsd.

Ofcourse hashing your password is a good thing. An intruder can only steal the hashed password and use it for the specified service until the password is changed and the hash becomes invalid. The advantage is the intruder could never 'read' your real typed in password should you have used it on other services.

But Ogone has made the hashing straight without a salt, which is a serious issue if you take rainbow tables into account. Using the rainbow table technique on an unsalted string allows an attacker to reverse engineer the password rather quickly.

Login into your test environment and goto https://secure.ogone.com/ncol/test/hash_pswd.asp to verify.

    echo -n yourpass | sha1sum

Refunds: not possible right after transaction.

It takes a while to approve your transaction. You will need to wait for its status to drop from 91 to 9. If your account type allows it, it's possible to refund by using another transaction. It was however not tested.

Support Helpdesk

Ogone's support helpdesk will answer promptly within a day, also for test accounts. You will need to contact them if you would like to add some features like for example 3d-secure. Most of my helpdesk request have been resolved in matter of days.

Credentials

You need to create a subaccount to access the API. Use that subaccount as the USERID or login. You will need to login with the password of the api user.

If you try to submit requests with a bad username or password your account can get blocked. To unblock your account you should go into the users panel and reactivate the account.
