Inspired by django-paypal

1. install django-webtopay

2. add WEBTOPAY_PASSWORD='pass' to your settings file

3. Add callback url:: url(r'^wtp/', include('webtopay.urls.makro')) (it should be relatively hard to guess)

4. Create a form for submission:

   form = WebToPaymentForm(
       dict(projectid = 123123,
           orderid = '3c3662bcb661d6de679c636744c66b62',
           accepturl = request.build_absolute_uri(),
           cancelurl = request.build_absolute_uri(),
           callbackurl = reverse('webtopay-makro'),
           paytext = "Payment for services",
           p_firstname = "Vardenis",
           p_lastname = "Pavardenis",
           p_email = "[email protected]",
           amount = 989, # 9 Lt 89 ct
           test = 1
           ),
       button_html="<input type='submit' value='Pay!'/>",
   )
   

5. Catch a django signal when the payment is completed:

   from webtopay.signals import payment_was_successful
   def process_payment(**kargs):
       trans = kargs['sender']
       if price_i_expect * 100 != trans.amount:
           log.error("Received wrong amount. Expected: %d, got: %d",\
               price_i_expect*100, trans.amount)
           return
       paid = True
       # from this point we assume customer paid
       #...
   payment_was_successful.connect(process_payment)
   

You should catch payment_was_flagged signal if you want to know when something went wrong:

from webtopay.signals import payment_was_flagged
def investigate_payment(**kargs):
    # kargs['sender'] is an instance of WebToPayResponse.
    # All fields are documented in webtopay/models.py
    log.warn("Payment went wrong for %s, please investigate",
        kargs['sender'].orderid)
payment_was_flagged.connect(investigate_payment)
