Return custom response on wrong http method usage in API

Hi everyone,

I’ve been exploring ways to handle errors caused by incorrect HTTP method usage. Currently, when a user makes an API request with the wrong HTTP method, Laravel returns its default error. I’d like to create a custom error response for such cases.

I came across some solutions, such as creating a middleware to handle this and passing the allowed routes as parameters. However, I feel there might be a better built-in way to achieve this in Laravel.

Add custom exception rendering logic to bootstrap/app.php. The exception in this case is MethodNotAllowedHttpException:

use Illuminate\Foundation\Application;
use Illuminate\Http\Request;
use Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException;

return Application::configure(basePath: dirname(__DIR__))
	...
	->withExceptions(function (Exceptions $exceptions) {
		$exceptions->render(function (MethodNotAllowedHttpException $e, Request $request) {
			if($request->expectsJson()) {
				return response()->json(['message' => 'Something'], status: 405);
			}
		});
	})

I included a check to see if a JSON response is expected. That way the default error page is rendered for non-API requests. You could also check if the requested path is relevant, e.g. $request->is('api/*').
