URL for Web API Management

I have a problem with the version of my web API:

[ApiVersion("1.0")]
[ApiVersion("2.0")]
[System.Web.Http.Route("api/v{version:apiVersion}/monitors")]
[ControllerName("Monitors")]
public sealed class MonitorsController : ApiController
{
   /* 
     /monitors/get?heartbeat=foo
   */
   [System.Web.Http.Route("api/v{version:apiVersion}/monitors/get")]
   [MapToApiVersion("1.0")]
   public JsonResult GetHeartbeatStatusV1(string heartbeat)
   {
      var x = new JsonResult {Data = "heartbeat v1"};
      return x;
   }
   [System.Web.Http.Route("api/v{version:apiVersion}/monitors/get")]
   [MapToApiVersion("2.0")]
   public JsonResult GetHeartbeatStatusV2(string heartbeat)
   {
      var x = new JsonResult { Data = "heartbeat v1" };
      return x;
   }
   /* 
      /monitors/get?alert=foo 
   */
   [System.Web.Http.Route("api/v{version:apiVersion}/monitors/get")]
   [MapToApiVersion("2.0")]
   public JsonResult GetAlertStatus(string alert)
   {
      var x = new JsonResult {Data = "alerts"};
      return x;
   }
   /* 
      /monitors/get?oDataQuery=foo 
   */
   [System.Web.Http.Route("monitors/get")]
   public JsonResult GetODataQuery(string oDataQuery)
   {
      var x = new JsonResult {Data = "oDataQuery"};
      return x;
   }
}

      

        
        
        
      

    

Above is my controller. I have a bunch of actions that I want to be able to call based on the version.

The problem is I also need all of them in order to be / get and then decide which method to call based on the parameter name, which is why I have:

[System.Web.Http.Route("api/v{version:apiVersion}/monitors/get")]

      

        
        
        
      

    

I thought I could decorate the method [MapToApiVersion("1.0")]

and [MapToApiVersion("2.0")]

to recognize which method is being called. However, in the exmaple posted, if I call api/v1.0/monitors/get?heartbeat=foo

, I get multiple actions error. If I call v2.0 it says it cannot find any method at all.

?

I would like to be able to do

http://foo:blah/api/v1.0/monitors/get?heartbeat=foo

http://foo:blah/api/v2.0/monitors/get?heartbeat=foo

http://foo:blah/api/v2.0/monitors/get?alert=foo

Is it possible?

EDIT

One thing I tried was splitting them into 2 different controllers in different namespaces.

[ApiVersion("2.0")]
[System.Web.Http.Route("api/v{version:apiVersion}/monitors")]
[ControllerName("Monitors")]
public sealed class MonitorsController : ApiController
{
    /* 
        /monitors/get?heartbeat=foo
    */
    [System.Web.Http.Route("api/v{version:apiVersion}/monitors/get")]
    [MapToApiVersion("2.0")]
    public JsonResult GetHeartbeatStatusV2(string heartbeat)
    {
        var x = new JsonResult {Data = "heartbeat v2"};
        return x;
    }
    /* 
        /monitors/get?alert=foo 
    */
    [System.Web.Http.Route("api/v{version:apiVersion}/monitors/get")]
    public JsonResult GetAlertStatus(string alert)
    {
        var x = new JsonResult {Data = "alerts"};
        return x;
    }

}

      

        
        
        
      

    

This error gets an error when searching multiple actions.

My WebApiConfig.cs looks like this:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
        var constraintResolver = new DefaultInlineConstraintResolver
                                 {
                                     ConstraintMap =
                                     {
                                         ["apiVersion"] = typeof(ApiVersionRouteConstraint)
                                     }
                                 };
        config.MapHttpAttributeRoutes(constraintResolver);
        config.AddApiVersioning();
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/v{version:apiVersion}/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}
