## Installation

```shell
pip install click-sdk
```

## Installation to Django

Add `'click_up'` in to your settings.py

```python
INSTALLED_APPS = [
    ...
    'click_up',
    ...
]
```

Add `'click_up'` credentials inside to settings.py

Click configuration settings.py

```python
CLICK_SERVICE_ID = "your-service-id"
CLICK_MERCHANT_ID = "your-merchant-id"
CLICK_SECRET_KEY = "your-secret-key"
CLICK_ACCOUNT_MODEL = "order.models.Order"  # your order model path.
CLICK_AMOUNT_FIELD = "amount"  # your amount field that's belongs to your order model

CLICK_COMMISSION_PERCENT = "(optional int field) your companies comission percent if applicable"
CLICK_DISABLE_ADMIN = False  # (optionally configuration if you want to disable change to True)
```

Create a new View that about handling call backs

```python
from click_up.views import ClickWebhook


class ClickWebhookAPIView(ClickWebhook):
    def successfully_payment(self, params):
        """
        successfully payment method process you can ovveride it
        """
        print(f"payment successful params: {params}")

    def cancelled_payment(self, params):
        """
        cancelled payment method process you can ovveride it
        """
        print(f"payment cancelled params: {params}")
```

Add a `click webhook` path to core of urlpatterns:

```python
from django.urls import path
from django.urls import include

from your_app.views import ClickWebhookAPIView

urlpatterns = [
    ...
    path("payment/click/update/", ClickWebhookAPIView.as_view()),
    ...
]
```

Run migrations

```shell
python3 manage.py makemigrations && python manage.py migrate
```

🎉 Congratulations you have been integrated click with django, keep reading docs. After successfull migrations check your
admin panel and see results what happened.

## Generate Pay Link

Example to generate link:

- Input

```python
from click_up import ClickUp

click_up = ClickUp(service_id="your-service-id",
                   merchant_id="your-merchant-id")  # alternatively you can use settings variables as well here.

# Generate Paylik payment link
paylink = click_up.initializer.generate_pay_link(
    id=1,  # id maybe order_id or acount_id (user_id, chat_id and etc..)
    amount=100,
    return_url="https://example.com"
)
```

- Output

```
https://my.click.uz/services/pay?service_id=service_id&merchant_id=merchant_id&amount=1000&transaction_param=1&return_url=https://example.com
```
