## The login_url Parameter

      

Instead of requiring users to enter passwords or 2FA codes on your website, you can attach a `login_url` button in Telegram chat. When clicked, Telegram securely prompts the user and passes verified user data via GET parameters to your auth endpoint.

      
```php
bot('sendMessage', [
    'chat_id'      => $chatId,
    'text'         => "🔐 Access Your Web Dashboard:
Click below to log in securely without entering credentials.",
    'parse_mode'   => 'HTML',
    'reply_markup' => [
        'inline_keyboard' => [
            [
                [
                    'text'      => '🚀 One-Click Web Login',
                    'login_url' => [
                        'url'                => 'https://botlify.cloud/login.php?telegram_oauth=1',
                        'forward_text'       => 'Log in to Botlify Cloud',
                        'request_write_access' => true
                    ]
                ]
            ]
        ]
    ]
]);
```
