A description of the Structure.Testy API is available at http://almworks.com/testy/apidocs/v3/

APIs can be accessed via Swagger UI, which is available at <You JIRA address>/rest/testy/3/rest-browser/. For example, the address to our public demo Jira instance is https://demo-structure.almworks.com, so the URL for Swagger UI is https://demo-structure.almworks.com/rest/testy/3/rest-browser/ 

Before trying to access Swagger UI, you must log in to your Jira instance first.
