Web API not working when doing POST passing a string to the method

Question

Why am I getting this error msg? {"Message":"No HTTP resource was found that matches the request URI 'http://www.test.com:7043/API/RunningValue_Import'.","MessageDetail":"No action was found on the controller 'RunningValue_Import' that matches the request."}

Here is the code:

public class RunningValue_ImportController : ApiController
{
    string temp001 = ""; //breakpoint here but it wont enter into the function below

    // POST api/RunningValue_Import
    public object PostRunningValue_Import(string xml)
    {
        string temp = String.Empty;
        try
        {
            temp = xml;
        }
        catch (Exception ee)
        {
            return new { isError = true, Msg = ee.ToString() };
        }
        return new { isError = false, Msg = "successful." };
    }
}

Fiddler:

POST http: //www.test.com:7043/API/RunningValue_Import HTTP/1.1

xml=WhateverStringGoesHere

Any ideas? Thanks

If you are using the default routing, then the request for URI = http://www.test.com:7043/API/RunningValue_Import will look for an Index() action method. Since your action method is named PostRunningValue_Import, it's not matching any route defined in the Routes Dictionary.

If you want, you can try giving it the ActionName as follows.

// POST api/RunningValue_Import    
[ActionName("Index")]
public object PostRunningValue_Import(string xml)
{
