Оба примера включают полную настройку Django, обработчики вебхуков и готовый к продакшену код!

Установка

Установите PayTechUZ с поддержкой Django:

pip install paytechuz[django]

Настройки Django

Добавьте конфигурацию PayTechUZ в настройки Django:

note

Вы можете удалить конфигурацию для платёжных провайдеров, которые вам не нужны. Настраивайте только те провайдеры, которые планируете использовать в вашем проекте.

# settings.py

INSTALLED_APPS = [
    # ...
    'paytechuz.integrations.django',
]

PAYTECHUZ = {
    'PAYME': {
        'PAYME_ID': 'your_payme_id',
        'PAYME_KEY': 'your_payme_key',
        'ACCOUNT_MODEL': 'payment.models.Invoice',  #  Your invoice model
        'ACCOUNT_FIELD': 'id',
        'AMOUNT_FIELD': 'amount',
        'ONE_TIME_PAYMENT': True,
        'IS_TEST_MODE': True,  # Set to False in production
    },
    'CLICK': {
        'SERVICE_ID': 'your_service_id',
        'MERCHANT_ID': 'your_merchant_id',
        'MERCHANT_USER_ID': 'your_merchant_user_id',
        'SECRET_KEY': 'your_secret_key',
        'ACCOUNT_MODEL': 'payment.models.Invoice',
        'ACCOUNT_FIELD': 'id',
        'COMMISSION_PERCENT': 0.0,
        'ONE_TIME_PAYMENT': True,
        'IS_TEST_MODE': True,  # Set to False in production
    },
    'UZUM': {
        'SERVICE_ID': 'your_service_id',  # ID сервиса Uzum для Biller URL
        'USERNAME': 'your_uzum_username',  # Для Basic Auth вебхука
        'PASSWORD': 'your_uzum_password',  # Для Basic Auth вебхука
        'ACCOUNT_MODEL': 'payment.models.Invoice',
        'ACCOUNT_FIELD': 'id',  # или 'id'
        'AMOUNT_FIELD': 'amount',
        'ONE_TIME_PAYMENT': True, # Set to False if you want to allow multiple payments for the same invoice
        'IS_TEST_MODE': True,  # Установите False в продакшене
    },
    'PAYNET': {
        'MERCHANT_ID': 'your_merchant_id',  # Paynet Merchant ID
        'SERVICE_ID': 'your_paynet_service_id',
        'USERNAME': 'your_paynet_username',
        'PASSWORD': 'your_paynet_password',
        'ACCOUNT_MODEL': 'payment.models.Invoice',
        'ACCOUNT_FIELD': 'id',
        'AMOUNT_FIELD': 'amount',
        'ONE_TIME_PAYMENT': True,
        'IS_TEST_MODE': True,
    }
}

Создайте модели для обработки заказов и платежей:

# shop/models.py
from django.db import models
from django.contrib.auth.models import User

class Order(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    product_name = models.CharField(max_length=255)
    total_amount = models.DecimalField(max_digits=12, decimal_places=2)
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return f"Order {self.id} - {self.product_name}"

# payment/models.py
from django.db import models
from django.contrib.auth.models import User
from django.utils import timezone
from shop.models import Order  # Import Order from shop app

class Invoice(models.Model):
    STATUS_CHOICES = (
        ('pending', 'Pending'),
        ('paid', 'Paid'),
        ('cancelled', 'Cancelled'),
    )

    user = models.ForeignKey(User, on_delete=models.CASCADE)
    order = models.ForeignKey(Order, on_delete=models.CASCADE)
    amount = models.DecimalField(max_digits=12, decimal_places=2)
    status = models.CharField(max_length=20, choices=STATUS_CHOICES, default='pending')
    created_at = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return f"Invoice {self.id} for Order {self.order.id}"

Представления (Views)

Создайте представления для обработки платежей:

note

Вам нужно создавать webhook представления только для тех платёжных провайдеров, которые вы используете. Удалите импорты и классы для ненужных провайдеров.

# payment/views.py
from paytechuz.integrations.django.views import (
    BasePaymeWebhookView,
    BaseClickWebhookView,
    BaseUzumWebhookView,

        invoice.save()

    def cancelled_payment(self, params, transaction):

    def successfully_payment(self, params, transaction):
        invoice = Invoice.objects.get(id=transaction.account_id)
        invoice.status = 'paid'
        invoice.save()

    def cancelled_payment(self, params, transaction):

                "balance": 0  # account.user.balance
            }
        }

URL маршруты

Настройте URL маршруты:

note

Добавляйте URL маршруты только для тех платёжных провайдеров, которые вы используете. Удалите импорты и пути для ненужных провайдеров.

# urls.py
from django.urls import path
from payment.views import PaymeWebhookView, ClickWebhookView, UzumWebhookView, PaynetWebhookView
from shop.views import OrderCreateView

urlpatterns = [
    # ...
    path('webhooks/payme/', PaymeWebhookView.as_view(), name='payme_webhook'),
    path('webhooks/click/', ClickWebhookView.as_view(), name='click_webhook'),
    path('webhooks/uzum/<str:action>/', UzumWebhookView.as_view(), name='uzum_webhook'),
    path('webhooks/paynet/', PaynetWebhookView.as_view(), name='paynet_webhook'),
    
    # Order creation endpoint
    path('order/create/', OrderCreateView.as_view(), name='order_create'),
]

Создание платёжных ссылок

Пример представления Django Rest Framework (DRF), которое обрабатывает создание заказа и генерирует платёжную ссылку на основе выбранного платёжного провайдера (без использования сериализаторов):

note

Настройте логику так, чтобы она включала только те платежные системы, которые вы хотите поддерживать. Удалите импорты и блоки elif для неиспользуемых систем.

# shop/views.py
