Do you know how we can create swagger file for REST services that are exposed within Pega? I could not find much documentation around that in PDN. From what I researched, I believe there is no support for that in Pega yet.
There is API2Swagger tool to generate Swagger JSON automatically by invoking REST service(s). It takes the manual work out of API documentation. The tool and its ReadMe are available at :https://github.com/pegasystems/api2swagger.git
