Dan,
WFA as of version 2.2, doesn't have any Swagger Specification for its RESTful APIs. We have REST Facade documentation which can be access using http://<wfa_server>/rest/docs
Are we working on it?
Currently no, but I think it can be a great value add to the product. I'll explore this more and see if we can provide it in future WFA releases.
warm regards,
Abhishek
