Laravel API Routes

you need to pass the fulldomain, not only the hostname

Route::group(['domain' => 'api.withdomain.name', 'prefix' => 'v1'], function () {

https://laravel.com/docs/5.7/routing#route-group-sub-domain-routing

I ended up going an alternate way. In RouteServiceProvider.php :

protected function mapApiRoutes()
    {
        Route::domain(env('API_ENDPOINT'))
             ->middleware('api')
             ->namespace($this->namespace)
             ->group(base_path('routes/api.php'));
    }

But it accomplishes the same thing. Your way is correct and its also did work!

Thanks for your time.

+1 @adrian.nuernberger, also if you are using a web server you will need to configure the virtual hosts accordingly pointing to the same laravel installation. However when developing using artisan serve, you can test it like:

Route::domain('api.localhost')->group(function() {
    Route::get('', function() {
        return 'hello api';
    });
});

Route::get('', function() {
    return 'hello web';
});

Now pointing browser to api.localhost:8000 and localhost:8000 should return the hello api and hello web response respectively.
