WebMethods internal APIs

I would like to know how much of internal APIs are exposed by WebMethods. Is there any document that has all the details about exposed APIs?

Thanks

I think you would be best on your way by going to the webMethods Extranet (http://Advantage.webmethods.com), there is a section there I remember called Bookshelf or similar named. You would be suprised how many API’s are exposed by webMethods. Java API volumes should be able to help you on your way
