WebAPI2绑定不工作

我是webapi 2的新手,正在尝试将我的api绑定到下面的调用。

有人知道我做错了什么吗?

呼叫: https://blabla.azurewebsites.net/myjohndeere/authenticated/e33dd8f74c97474d86c75b00dd28ddf8?oauth_token=1539dccf-d935-4d9e-83be-e00f76cabbb9&oauth_verifier=B22dWL

[RoutePrefix("myjohndeere")]
public class ApiMyJohnDeereController : ApplicationController
{

    [HttpGet, Route("authenticated/{callbackId}")]
    [SwaggerResponse(HttpStatusCode.OK, Type = typeof(ApiResponseModel))]
    [SwaggerResponse(HttpStatusCode.InternalServerError, "An unknown error occurred")]
    [SwaggerResponse(HttpStatusCode.BadRequest, "Missing FieldMappings")]
    public IHttpActionResult Authenticated(string callbackId,[FromUri]string oauth_token, [FromUri]string oauth_verifier)
    {
        ...
    }
