How to create a payment
- Prepare your order's data:
data = {
"order_id": f"order-123",
"amount": 400.00,
"parts_count": 2, # optional, default value is '2'
"merchant_type": "II", # optional, default value is 'II'
"products": [
{
"name": "Телевизор",

}
],
# also optional fields (can be set in your cabinet):
"response_url": "http://shop.com/response",
"redirect_url": "http://shop.com/redirect",
}- Get your redirect url:
from payparts.use_cases import GetRedirectUrlUseCase
redirect_url = GetRedirectUrlUseCase().execute(data)- Redirect a user to the url.
How to process a callback
Whenever a callback is processed a signal will be sent with the result of the transaction.
There are two signals (payparts.signals):
-
pay_parts_success_callback- if signature is valid. -
pay_parts_invalid_callback- if signature is not valid.
Connect the signals to actions to perform the needed operations when a successful payment is received:
from payparts.signals import pay_parts_success_callback, pay_parts_invalid_callback
from orders.models import Order
def success_callback(sender, log, request, **kwargs):
# ensure success state
if log.is_success:
order = Order.objects.get(pk=log.order_id)
order.set_success_payment_state()
pay_parts_success_callback.connect(success_callback)
