Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, called RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.
With Intersystems indicating ZEN pages are being deprecated, I'm looking to find out how to add custom configuration pages for the management portal using the new method similar to the new Rules editor.
From what I can tell the new method uses rest pages using JWT Authentication, and has a mechanism to use the session cookie to generate the JWT token.
