Add a basic endpoint

To create an endpoint, create a class that derives from HeadlessApiControllerBase class. Apply the RoutePrefix attribute to the class level, that define the url to this endpoint.

Basic endpoint

For this example, we create a TestPage controller, that would have the url <your domain name>/headlessapi/Test

    [RoutePrefix(Routes.RootUri + "/TestPage")]
    public class TestPageController:HeadlessApiControllerBase
    {

    }

Add a HTTP GET method that would simply return a string "This is a test page"

    [RoutePrefix(Routes.RootUri + "/TestPage")]
    public class TestPageController:HeadlessApiControllerBase
    {
        [HttpGet]
        [Route("", Name = "TestPage")]
        public IHttpActionResult Get()
        {           
            return Ok("This is a test page");
        }
    }

If the Litium instance running is on server.localtest.me, the url to the test page would be,  http://server.localtest.me/headlessApi/TestPage

Open postman and send a GET request to this page, would produce following output.
