I'm moving a service from using an EZD to Refinitive Real-time Optimized, and getting a bit confused by the documentation.
I've been given an AppKey and read a PDF on Real-time Oprimized talking about providing Client_ID, whereas the C++ documentation on the API we're using (https://github.com/Refinitiv/Real-Time-SDK/tree/master/Cpp-C/Ema/Docs) refers to neither instead talking about username, password, and maybe applicationId (which seems to be a number however).
Does anyone know how they all link together?
