I am in the process of converting an existing PowerBuilder application that communicates with a mainframe via an emulator to one using APIs with REST/JSON. I have looked at the examples in the Appeon PowerBuilder 2017 R3 Help and was wondering if the URLs listed in the examples are active. If not, does anyone know of any REST/JSON servers that I could use to retrieve data to become familiar with the client side code until my team is able to get our server side code working? Thanks.
