About

Implementation of the iDEAL v3.3.1 specification in Python.

Installation

You can install ideal either via the Python Package Index (PyPI) or from source.

To install using pip:

$ pip install -U ideal

Usage

It is assumed you have already requested access at your bank for iDEAL.

  1. Install the ideal library:

    $ pip install ideal
    
  2. Generate or locate your certificates (cert.cer, and priv.pem) and your bank’s public certificate (here named ideal_v3.cer but depends on your bank), and place them in a folder where your web application can access them.

  3. Create a config file called ideal.cfg (or copy and modify the ideal-example.cfg):

    [ideal]
    debug = 1
    private_key_file = priv.pem
    private_key_password = secret
    private_certificate = cert.cer
    certificates = ideal_v3.cer
    merchant_id = 123456789
    sub_id = 0
    merchant_return_url = https://www.example.com/ideal/callback/
    acquirer = ING
    
  1. In Python, make sure your settings are initialized by loading the config file:

    from ideal.conf import settings
    settings.load('ideal.cfg')
    
    # You may adjust (or completely define) your settings (capitalized) in Python as well
    settings.DEBUG = True
    
  2. After your settings are loaded, you can communicate with iDEAL:

    from ideal.client import IdealClient
    ideal = IdealClient()
    
    response = ideal.get_issuers()
    print response.issuers
    

Settings

These settings are lower-case and stored in your ideal.cfg file (or in Django’s settings.py, prefixed with IDEAL_).

DEBUG (boolean)
Uses the test URL of the acquirer if set to True, otherwise the production URL is used (default: True).
PRIVATE_KEY_FILE (string)
Absolute path to the merchant’s private key (default: priv.pem).
PRIVATE_KEY_PASSWORD (string)
Password to access the merchant’s private key.
PRIVATE_CERTIFICATE (string)
Absolute path to the merchant’s private certificate (default: cert.cer).
CERTIFICATES (list or comma-separated string if file config is used)
Absolute path the the acquirer’s iDEAL certificate (default: ideal_v3.cer).
MERCHANT_ID (string)
The ID of the online shop, received by the acceptor during the iDEAL registration process.
SUB_ID (string)
Sub ID of the online shop, also received during the registration process (default: 0).
MERCHANT_RETURN_URL (string)
The callback URL for iDEAL. The customer is redirected to this URL after the payment process at the acquirer.
EXPIRATION_PERIOD (string)
The time a transaction is valid for in ISO 8601 format, minimum is 1 minute, maximum is 1 hour (default: PT15M).
ACQUIRER (string)
Acquirer code to identify the endpoint. Valid values are: [ING, RABOBANK] (default: None).
ACQUIRER_URL (string)
Overrides the default acquirer URL and ignores the ACQUIRER and DEBUG setting (default: None).
LANGUAGE (string)
Response language in ISO 639-1 format, only Dutch (nl) and English (en) are supported (default: nl).

Testing

To run all unit tests, download the entire package and run:

$ python setup.py test

Contrib

Django

  1. All settings can be capitalized and prefixed with IDEAL_ and placed in Django’s settings.py file, rather than using a configuration file. Of course, you may still use the settings file method.

  2. Add ideal.contrib.django.ideal_compat to your INSTALLED_APPS.

  3. Run python manage.py migrate to create the Issuer table in your database, to store a local copy of all issuers.

  4. Run python manage.py sync_issuers to fill the Issuer table with a list of issuers. You should run this command every day or so using a cronjob.

  5. You should create a view to handle the iDEAL callback and add the URL (as defined in your settings as MERCHANT_RETURN_URL) to your urls.py. Below, you’ll find an example view to redirect the use depending on the transaction status:

    from django.views.generic.base import RedirectView
    from ideal.client import IdealClient, TransactionStatus
    from ideal.exceptions import IdealException
    
    class IdealCallbackView(RedirectView):
        permanent = False
    
        def get_redirect_url(self, **kwargs):
            """
            Simplistic view to handle the callback. You probably want to update your database with the transaction
            status as well, or sent a confirmation email, etc.
            """
            client = IdealClient()
    
            try:
                response = client.get_transaction_status(self.request.GET.get('trxid'))
                if response.status == TransactionStatus.SUCCESS:
                    # Redirect to some view with a success message.
                    return '<payment success url>'
            except IdealException, e:
                # Do something with the error message.
                error_message = e.message
    
            # Redirect to some view with a failure message.
            return '<payment failed url>'
    
  6. Optionally, you can add the the following to your main urls.py to test your configuration and perform all iDEAL operations via a web interface:

    if settings.DEBUG:
        urlpatterns += [
            url(r'^ideal/tests/', include('ideal.contrib.django.ideal_compat.test_urls')),
        ]
    
  7. If you are in DEBUG mode and use runserver, you can point your browser to: http://localhost:8000/ideal/tests/.
