# Click Integration

Click is a widely used payment system in Uzbekistan. This guide shows how to
integrate Click with PayTechUZ.

## Installation

```bash
pip install paytechuz
```

## Basic usage

### Create a gateway

```python
import os
from paytechuz.gateways.click import ClickGateway

gateway = ClickGateway(
    service_id="your_service_id",
    merchant_id="your_merchant_id",
    merchant_user_id="your_merchant_user_id",
    secret_key="your_secret_key",
    is_test_mode=True,  # True for testing, False for production
)
```

### Create a payment

```python
payment = gateway.create_payment(
    id="12345",          # Invoice ID
    amount=500.00,       # Amount in UZS
    return_url="https://example.com/return"
)

print(f"Payment URL: {payment}")
# Redirect the user to the payment URL
```

### Check payment status

```python
status = gateway.check_payment("transaction_id")
print(f"Status: {status['status']}")
```

## Webhooks

Webhooks are handled through the framework integrations — `BaseClickWebhookView` for
Django and `ClickWebhookHandler` for FastAPI. Signature verification, transaction
persistence and the response format are done for you; you only override the event
methods.

See the sections below.

## Django integration

### Settings.py

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

PAYTECHUZ = {
    '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': 'shop.models.Order',
        'ACCOUNT_FIELD': 'id',
        'AMOUNT_FIELD': 'amount',
        'IS_TEST_MODE': True,
    }
}
```

### Views.py

```python
from paytechuz.integrations.django.views import BaseClickWebhookView
from .models import Order

class ClickWebhookView(BaseClickWebhookView):
    def successfully_payment(self, params, transaction):
        order = Order.objects.get(id=transaction.account_id)
        order.status = 'paid'
        order.save()

    def cancelled_payment(self, params, transaction):
        order = Order.objects.get(id=transaction.account_id)
        order.status = 'cancelled'
        order.save()
```

### URLs.py

```python
from django.urls import path
from .views import ClickWebhookView

urlpatterns = [
    path('webhooks/click/', ClickWebhookView.as_view(), name='click_webhook'),
]
```

## FastAPI integration

```python
from fastapi import FastAPI, Request
from paytechuz.gateways.click import ClickGateway
from paytechuz.integrations.fastapi import ClickWebhookHandler
import os

app = FastAPI()

# Create the gateway
click = ClickGateway(
    service_id=os.getenv('CLICK_SERVICE_ID'),
    merchant_id=os.getenv('CLICK_MERCHANT_ID'),
    merchant_user_id=os.getenv('CLICK_MERCHANT_USER_ID'),
    secret_key=os.getenv('CLICK_SECRET_KEY'),
    is_test_mode=True
)

@app.post("/payment/create")
async def create_payment():
    payment_url = click.create_payment(
        id="12345",
        amount=500.00,
        return_url="https://example.com/return"
    )
    return {"payment_url": payment_url}

@app.post("/webhooks/click")
async def webhook(request: Request):
    handler = ClickWebhookHandler(
        service_id=os.getenv('CLICK_SERVICE_ID'),
        secret_key=os.getenv('CLICK_SECRET_KEY'),
        account_model=Order
    )
    return await handler.handle_webhook(request)
```

## Configuration

### Test mode

Use these credentials for testing:
- **Service ID**: `test_service_id`
- **Merchant ID**: `test_merchant_id`
- **Test card**: `8600 0691 9540 6311`

### Production mode

1. Register at [Click Business](https://business.click.uz)
2. Get your production credentials
3. Set `is_test_mode=False`

## Error handling

```python
from paytechuz.core.exceptions import PaymentException

try:
    payment = gateway.create_payment(
        id="12345",
        amount=500.00,
        return_url="https://example.com/return"
    )
except PaymentException as e:
    print(f"Click error: {e.code} - {e.message}")
```

## Webhook response codes

Click expects specific response codes:

- `0` — Success
- `-1` — Signature verification failed
- `-2` — Invalid amount parameter
- `-3` — Action not found
- `-4` — Already paid
- `-5` — User does not exist
- `-6` — Transaction does not exist
- `-7` — Failed to update user
- `-8` — Error in request from Click
- `-9` — Transaction cancelled
