The Right Way to Use env() in Laravel

Use env() only in config files. Then call config() in your app code.

Example: WhatsApp API Setup

  1. Create a config file config/whatsapp.php:

return [
    'api_key' => env('WHATSAPP_API_KEY'),
    'webhook_secret' => env('WHATSAPP_WEBHOOK_SECRET'),
];

  1. Add these to your .env file:

WHATSAPP_API_KEY=your_api_key
WHATSAPP_WEBHOOK_SECRET=your_webhook_secret

  1. Use config() in your app logic:

$apiKey = config('whatsapp.api_key');
$webhookSecret = config('whatsapp.webhook_secret');

  1. Update your config cache after any change:

php artisan config:clear
php artisan config:cache
