Payment notifications

If you want to set up POST notifications from Qiwi when payment is received, you have to add qiwi_kassa.urls in your project urls:

urlpatterns.append(
    path('qiwi/', include(('qiwi_kassa.urls', 'qiwi_payments'), namespace='qiwi')),
)

Then you notification URL will be: <your_hostname>/qiwi/notify/

When payments is received and signatures are OK the payment_received signal will be broadcasted. Here is an example how to handle the signal:

from django.dispatch import receiver
from qiwi_kassa.models import Invoice
from qiwi_kassa.signals import payment_received
from qiwi_payments.constants import PaymentStatus

@receiver(payment_received, sender=Invoice)
def payment_handler(sender, **kwargs):
    bill_id = kwargs.get('bill_id')
    invoice = Invoice.objects.get(bill_id=bill_id)
    invoice.status = PaymentStatus.PAID
    invoice.save()
    print('$$$$!')
