Docdata Payments Gateway integration for django-oscar

django-oscar-docdata

Payment gateway integration for Docdata Payments in django-oscar. DocData Payments is a large payment gateway based in The Netherlands that supports more then 40 international payment methods.

Installation

Install via pip:

pip install django-oscar-docdata

Configuration

Configure the application:

DOCDATA_MERCHANT_NAME
Credentials as supplied by the payment provider.
DOCDATA_MERCHANT_PASSWORD
Credentials as supplied by the payment provider.
DOCDATA_PROFILE
The payment-methods profile that is created in the Docdata Backoffice. By default, this is named “standard”.
DOCDATA_TESTING
Whether or not to run in testing mode. Defaults to True.

Add to urls.py:

from oscar_docdata.dashboard.app import application as docdata_app

urlpatterns += patterns('',
    url(r'^api/docdata/', include('docdata.urls')),
    url(r'^dashboard/docdata/', include(docdata_app.urls)),
)

Add to settings.py:

OSCAR_DASHBOARD_NAVIGATION[2]['children'].insert(1, {
    'label': _('Docdata Orders'),
    'url_name': 'docdata-order-list',
})

As recommendation, temporary log all events from this package as well:

LOGGING = {
    # ...

    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse',
        }
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        },
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        # ...

        'suds': {
            'handlers': ['console'],
            'level': 'DEBUG',
            'propagate': True,
        },
        'oscar_docdata': {
            'handlers': ['mail_admins', 'console'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

Integration into your project

Please view the sandbox application how to integrate the application. This includes the project-specific desisions such as:

  • How to create payment events.
  • Which fields to map to the “house number” field. (e.g. line2, line3 or a custom field).
  • Whether to cancel an order when the customer aborted the payment.
  • When to submit confirmation emails.

Configuration of the Docdata Backoffice

Make sure the following settings are filled in:

  • The “Payment Method names” need to be added to a profile (default value of DOCDATA_PROFILE is “standard”).
  • The notification URL and return URL need to be set. Example values:
  • Success: http://example.org/api/docdata/update_order/?callback=SUCCESS&order_id=
  • Cancelled: http://example.org/api/docdata/update_order/?callback=CANCELLED&order_id=
  • Error: http://example.org/api/docdata/update_order/?callback=ERROR&order_id=
  • Pending: http://example.org/api/docdata/update_order/?callback=PENDING&order_id=
  • Update URL: http://example.org/api/docdata/update_order/?order_id=

Caveats

While working with the Docdata 1.0 and 1.2 API, we found the following limitations:

  • Address fields are oriented towards Dutch address standards. Passing international addressfields is hard, or requires hacking, for example:
  • Faking the house number (because the US address fields have no official field for that).
  • Streets have a limit of 35 characters, so the “Address Line 1” should be truncated.
  • Passing invalid address fields could cause PayPal, VISA or MasterCard transactions to fail.
  • PayPal payments may fail when the “state” field is invalid (e.g. because of a typoo). This is a check done by PayPal, Docdata passes the responsability to the merchant (you).
  • The <billTo><address><state> field is typically ignored. Provide it via <invoice><shipTo><address><state>. Seriously.
  • The individual payment objects have a status value, but the payment cluster does not. This means that there is no global status value to read. If an order has been cancelled before starting a payment, there is no way to tell from the API. The only way this can be detected, is when the customer presses the “Back to shop” link, which calls the cancel callback url. You may want to catch the return_view_called signal for this.
  • Determining that an order has been paid happens by comparing “received >= expected”. This could break with currency conversions. Again, because the payment cluster status is not exposed in the API. As workaround, there is a DOCDATA_PAYMENT_SUCCESS_MARGIN setting to add a margin of 100 cents.

We hope this will be addressed by Docdata Payments in future versions of the API.
