Hello,
We are building an integration for one of our client with their old SAP HCM. They haven't migrated to Successfactors yet hence need an integration into their old SAP HCM. I am unable to find an API description similar to the one for Successfactors like this one here. Is there something publicly accessible? Or where can I get the latest technical descriptions about the endpoints and how I can interact with an old SAP HCM? This seems unnecessary difficult to find.
