You probably need to enable CORS:

In your WebApiConfig.cs file, add this:

var cors = new EnableCorsAttribute("*", "*", "*");
config.EnableCors(cors);

CORS is a check by the browser to enforce same origin policy when the call is made using scripting. You won't see it when using something like Fiddler or when accessing the api directly in the browser.
