How do I get a copy of the epicor rest-api development documentation?

I’m a programming developer from China,epicor seems just have only a few developer in China, so I can’t got any help in Chinese Internet, now I have some secondary development needs in Epicor, but I don’t know how to get started.As I browsed the forums, I found some information.but when me wants to got the document in http://servername/ERP101400/api ,404 is displayed on the web page. so how can I got some document or help for Epicor.

Its /api/help

What version are you on?

I have changed my url but it still 404,and my version is 10.1.400

That version you had to turn on the rest api in admin console that was the first time it came out and it was very buggy

In admin console you can enable rest interface

I can’t seem to find a configuration option for the rest interface in the admin console, perhaps I can get a graphic tutorial somewhere?

I would upgrade before trying to do anything with rest at that version. Everything will be a struggle.
