sofort 0.4.3

Installation

$ pip install git+https://github.com/spreecode/python-sofort.git

Usage

import sofort
import some_abstract_http_framework as webserver
import some_abstract_data_storage as db

client = sofort.Client(my_user_id, my_api_key, my_project_id,
    success_url='https://mysite.de/thanks.html',
    abort_url='https://mysite.de/abort_payment.html',
    notification_urls={
        'default': 'https://mysite.de/notify.php?' + sofort.TRANSACTION_ID
    })

payment_data = client.payment(
    200,
    reasons=[
        'Invoice 0001 payment',
        sofort.TRANSACTION_ID
    ]
)

db.save_transaction(payment_data.transaction)
webserver.redirect(payment_data.payment_url)

When payment is proccessed, client will be redirected to success_url and Sofort server will send POST-request to notification_urls as soon as transaction status will be changed. You can use sofort.TRANSACTION_ID in URL params, so notification url could be like this:

'http://mysite.de/notify.php?trn=' + sofort.TRANSACTION_ID

it will be substituted to something like

http://mysite.de/notify.php?trn=123456-321321-56A29EC6-066A

So you can catch transaction ID and check it’s status (all responses are wrapped with Schematics models)

>>> details = client.details('123456-321321-56A29EC6-066A')
>>> details[0]._data
{'amount': Decimal('234.00'),
 'amount_refunded': Decimal('0.00'),

 'test': True,

 'user_variables': None}

Testing

$ pip install -e '.[test]' # to obtain mock library
$ python setup.py test

Be careful, transaction ID contains some sensitive data

123456-321321-56A29EC6-066A
^^^^^^ ^^^^^^
   |      |
User ID   |
      Project ID

Of course this data will be visible to customer on payment page, and it’s almost useless without API key. Still I think it’s bad idea to store unmasked transaction IDs in repo.
