Web API equivalent to Web Service [.asmx]

I am new to Web API. I have implemented some Web service methods [.asmx] using deprecated WebServices - with Attributes [WebMethod] and was able to place all my different methods in the .asmx file and was able to call them by the webmethod name in my ajax calls.

I am trying to move this to WebAPI, and i dont see that i could use different methods here in the WebAPI.

for ex., in my WebService.asmx file, i could declare :

 [WebMethod]
    public void LoadReport()
    {
        ...
    }


 [WebMethod]
    public void LoadReport2()
    {
      ...
    }

But in WebAPI, all i could utilize is the Get(), Put(), Post() and Delete().

How do i declare these 2 different methods in Web API ?

Use the attribute routing in web api.

for example:

[RoutePrefix("api/Data")]
    public class DataController : ApiController
    {
      [Route("LoadReport")]
        [HttpGet]
        public HttpResponseMessage LoadReport()
            {
                ...
            }

        [Route("LoadReport2")]
        [HttpGet]
        public HttpResponseMessage LoadReport2()
            {
                ...
            }

you can access these methods by calling

http://localhost:<port>/api/sample/LoadReport
http://localhost:<port>/api/sample/LoadReport2

if you use .Net 4.5.2, ensure that the Attribute Routing is enabled. Add the below line under Register method of App_Start\WebAPiConfig.cs file:

public static void Register(HttpConfiguration config)
{    
         config.MapHttpAttributeRoutes(); //enable Attribute routing

In WebApiConfig.cs :

public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }

and in my Controller :

namespace WebAPIa.Controllers
{
   // [Route("api/[controller]")]
    public class DataController : ApiController
    {
        [ActionName("LoadReport")]
        [HttpGet]
        public HttpResponseMessage LoadReport()
        {

           return Request.CreateResponse("Testing LoadReport");
        }

        [ActionName("LoadReport2")]
        [HttpGet]
        public HttpResponseMessage LoadReport2()
        {
            return Request.CreateResponse("Testing LoadReport2");
        }
    }
}
