Adding extra info to a logged notifications

The notification_log_items table has a JSON column called extra that allows you to store any value you want.

To fill up the extra column, add a function named logExtra to your notification and let it return an array that should be stored in the extra column when the notification gets logged.

use Illuminate\Notifications\Events\NotificationSending;

// in a notification
public function logExtra(NotificationSending $event): array
{
    return ['extraKey' => 'extraValue'];
}
