Usage

1. Create order and init payment with default params:

   from django_paynova import create_order, PaynovaException
   try:
       pp = create_order({
           'orderNumber': '0001',
           'currencyCode': 'EUR',
           'totalAmount': 10
       })
       # TODO: redirect to pp.url
   except PaynovaException as e:
       # TODO: handle exception

   create_order takes dictionary with Create Order parameters

2. Handle Event Hook Notifications:

   from django.dispatch import receiver
   from django_paynova.signals import paynova_payment
   
   @receiver(paynova_payment)
   def paynova_payment_signal(sender, status, params, **kwargs):
       # TODO: handle paynova payment notification

   where

   • sender - PaynovaPayment model
   • status - status of payment
   • params - payment params from Paynova

Advanced

Also you can create order and initialize payment separately:

from django_paynova import create_order, initialize_payment, PaynovaException
try:

    # create order

    pp = create_order({
        'orderNumber': '0005',
        'currencyCode': 'EUR',
        'totalAmount': 10
    }, init_payment=False)

    # init payment. http://docs.paynova.com/display/API/Initialize+Payment

    pp = initialize_payment({'orderId': pp.order_id})

    # TODO: redirect to pp.url

except PaynovaException as e:
    # TODO: handle exception

• create_order takes dictionary with Create Order parameters
• initialize_payment takes dictionary with Initialize Payment parameters

Errors

If Paynova return an error, PaynovaException will be raised

from django-paynova import create_order, PaynovaException

    pp = create_order()

    # process exception
