    }

### Usage

Valid URL should always end with backlash: https://www.google.com/
Following URL will be considered invalid: http://www.google.com

#### Using views:

Add following in your project's urls.py file:
    
    urlpatterns = [
        ... ,
        path('your_endpoint/', include('urlshort.urls'))
    ]
    
##### shorten_url

    ENDPOINT = defined in urlpatterns for the package's urls

    POST request:
    
        curl --location 'your_server_domain/ENDPOINT/apis/url/create' \
        --data '{
            "original_url": "https://www.postgresql.org/docs/7.3/arrays.html"
        }

        for example:
            curl --location 'your_server_domain/your_endpoint/apis/url/create' \
            --data '{
                "original_url": "https://www.postgresql.org/docs/7.3/arrays.html"
            }

    SCHEME and DOMAIN = defined in your env/secrets file
    
    response:
        
        {
            "status": "01",
            "data": {
                "created_at": "2023-10-25T12:00:12.623Z",
                "original_url": "https://www.postgresql.org/docs/7.3/arrays.html",
                "short_url": "SCHEME://DOMAIN/ENDPOINT/CWmPYIc",
                "expires_at": "2023-10-26T12:00:12.621Z",
                "alias": "CWmPYIc",

    original_url = "https://www.google.com/"
    
    from urlshort.helpers import shorten_url
    
    short_url = shorten_url(value)

        unqiue_id = Pq3E8yy
    
    from urlshort.helpers import get_original_url
    
    original_url = get_original_url(unique_id)
