🚀 Jumpstart Your Integration

1. Generating Checkout Links

Drop in your merchant credentials and generate secure payment references instantly.

from unipay_uz.gateways.payme import PaymeGateway
from unipay_uz.gateways.click import ClickGateway
from unipay_uz.gateways.uzum.client import UzumGateway
from unipay_uz.gateways.paynet import PaynetGateway

# Setup Payme 
payme_client = PaymeGateway(
    payme_id="MERCHANT_ID_HERE",
    payme_key="SECRET_KEY_HERE",
    is_test_mode=True  # Toggle for production deployment
)

# Setup Click 
click_client = ClickGateway(
    service_id="APP_SERVICE_ID",
    merchant_id="APP_MERCHANT_ID",
    merchant_user_id="APP_USER_ID",
    secret_key="SECRET_HASH_KEY",
    is_test_mode=True 
)

# Create an invoice / checkout URL
checkout_url_payme = payme_client.create_payment(
    id="ORD-998877",
    amount=250000,  # Value in UZS (Som)
    return_url="https://your-platform.uz/checkout/success",
    account_field_name="order_id"  # Identifier key requested by Payme
)

# Generate Click invoice
checkout_url_click = click_client.create_payment(
    id="ORD-998877",
    amount=250000, 
    description="Subscription Renewal",
    return_url="https://your-platform.uz/checkout/success"
)

2. Provider-Specific Details

Paynet Interactions

Paynet processes invoices predominantly via mobile devices, rendering direct app redirection links.

# Create a Paynet invoice (amount in Tiyin: 1 UZS = 100 Tiyin)
paynet_url = paynet_client.create_payment(
    id="ORD-998877", 
    amount=25000000 
)
# Returns: https://app.paynet.uz/?m={merchant_id}&c=ORD-998877&a=25000000

Note: Paynet relies on JSON-RPC 2.0 Webhooks for fulfillment acknowledgment, not return URLs.

Uzum Biller Integration

Generate an open-service gateway redirect for the Uzum ecosystem.

uzum_url = uzum_client.create_payment(
    id="ORD-998877",  
    amount=50000,  # Value in UZS
    return_url="https://your-platform.uz/sync"  
)

🏗️ Deep Dive: Django Blueprint

Integrating real-time transaction state updates using Django is built into unipay-uz.

Configuration Requirements

First, add your credentials in settings.py:

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

TOLOV = {
    'PAYME': {
        'PAYME_ID': 'STORE_ID',
        'PAYME_KEY': 'STORE_KEY',
        'ACCOUNT_MODEL': 'shop.models.Transaction',
        'ACCOUNT_FIELD': 'ref_id',
        'AMOUNT_FIELD': 'total_amount',
        'ONE_TIME_PAYMENT': True,
    },
    'CLICK': {
        'SERVICE_ID': 'SRV_ID',
        'MERCHANT_ID': 'MCH_ID',
        'MERCHANT_USER_ID': 'USR_ID',
        'SECRET_KEY': 'SECRET',
        'ACCOUNT_MODEL': 'shop.models.Transaction',
        'ACCOUNT_FIELD': 'ref_id',
        'COMMISSION_PERCENT': 0.0,
        'ONE_TIME_PAYMENT': True,
    }
}

Listening to Webhooks

Create specialized views that inherit from our base webhook classes.

# views.py
from unipay_uz.integrations.django.views import BasePaymeWebhookView, BaseClickWebhookView
from shop.models import Transaction

class PaymeCallbackReceiver(BasePaymeWebhookView):
    def successfully_payment(self, params, transaction):
        order = Transaction.objects.get(ref_id=transaction.account_id)
        order.mark_as_paid()

    def cancelled_payment(self, params, transaction):
        order = Transaction.objects.get(ref_id=transaction.account_id)
        order.mark_as_failed()

class ClickCallbackReceiver(BaseClickWebhookView):
    def successfully_payment(self, params, transaction):
        order = Transaction.objects.get(ref_id=transaction.account_id)
        order.mark_as_paid()

    def cancelled_payment(self, params, transaction):
        order = Transaction.objects.get(ref_id=transaction.account_id)
        order.mark_as_failed()

Map these receivers in your urls.py:

from django.urls import path
from .views import PaymeCallbackReceiver, ClickCallbackReceiver

urlpatterns = [
    path('api/v1/webhooks/payme/', PaymeCallbackReceiver.as_view()),
    path('api/v1/webhooks/click/', ClickCallbackReceiver.as_view()),
]
