Last steps to get your "hello world" response working by creating your first endpoint and route.
If you've followed the Get started guide you should be able to fire off a request to the root of your URI and get a response. Please note that you must do a GET request and include the Accept header with application/json as the value. The response you get should look like this:
{
"message": "Welcome to the API."
}
Add more endpoints to the app/endpoint/ directory and
learn more about how to work with endpoints by reading about endpoints in the documentation.
When you've added more endpoints you also need to set up routes that points to the new endpoints. Add those routes to the app/configuration/routes.php file and read more about how routes works in the documentation.
