We plan to migrate a PowerBuilder classic application to PowerServer 2021. Once migrated, can PowerServer 2021 REST API's be called from a non-PowerBuilder application?

The swagger docs are for the internal APIs... not for retrieving/updating data from/to the deployed DataWindows.

Hi Amit;

  You can use "http://localhost:5008/swagger/index.html" in your web browser when the PS2021 server is running on your developer machine to get the documentation on the RESTAPI's that the PS Project generated plus the Built-in ones. Just replace port 5008 in my URL example with the port that you are using for your PS2021 server. Also, makes sure that the Web Browser & PS2021 server are running locally on your development machine.

  Now you can use the API documentation to allow other App's to call any of those RESTFul API's.  HTH

Regards ... Chris

Is there a way to generate swagger documentation for the retrieve/update calls?

Engineering suggests not to reuse the generated C# project for non-PB apps. For your non-PB projects, you should create completely separate C# project from your existing DataWindows.

There are some tutorials and other tech resources how to do this at the bottom of this page: https://www.appeon.com/products/powerbuilder/dotnet-datastore-rest-apis

There is also lots of Elevate sessions about this: https://www.youtube.com/playlist?list=PL2Eo5uXB4T3nendKrWoSmPeX92U8JbgyP
