It is hard to handle multiple parameters on the action directly. The better way to do it is to create a view model class. Then you have a single parameter but the parameter contains multiple data properties.

public class MyParameters
{
    public string a { get; set; } 
    public string b { get; set; }
}

public MyController : ApiController
{
    public HttpResponseMessage Get([FromUri] MyParameters parameters) { ... }
}

Then you go to:

http://localhost:12345/api/MyController?a=par1&b=par2

If you want to use "/par1/par2", you can register an asp routing rule. eg routeTemplate: "API/{controller}/{action}/{a}/{b}".
