Is there a default verb applied to a Web API ApiController method?

Question

I\'ve been looking at the code (in https://github.com/patelsan/WebAPIAuthentication) from this article: http://www.codeproject.com/Articles/630986/Cross-Platform-Authenticat

Typically method name matching is thought of this way. Looking at the WebAPI source, however, there is a branch of logic for fallback. If the method name doesn't map (through attribute, or convention) to a supported HTTP verb, then the default is POST.

By default action selection happens through ReflectedHttpActionDescriptor class. The important method here is GetSupportedHttpMethods(). In relevant part the code reads:

        if (supportedHttpMethods.Count == 0)
        {
            // Use POST as the default HttpMethod
            supportedHttpMethods.Add(HttpMethod.Post);
        }
