How can I handle validation errors specifically for Laravel API requests?

For API validation errors in Laravel, when a `FormRequest` fails validation, Laravel automatically redirects. For APIs, you need to override the `failedValidation` method in your `FormRequest` class or catch the `ValidationException` in your `app/Exceptions/Handler.php`. In the handler, you can format the validation errors into a JSON response, typically returning a 422 Unprocessable Entity status code with an array of validation error messages keyed by the field names.
