How to connect to a specific deployed RTDS service using Pyhon RDL?

I've been able to successfully hand over on-premise server IPs, dacs users and subscribe as snapshot or stream to RICs and specific fields. I was wondering if it was possible to open_session and/or get_data, etc to a specific service within our RTDS ADH service list. e.g. ABC_SELECTFEED

Not exactly sure if this is something that is tied to the configuration file for session establishment or if it is something that can be handed over as a flag when opening a session such as:

rd.open_session(config_name=".\\Configuration\\refinitiv-data.custom.config.json")

Thanks in advance for your help

Thank you for reaching out to us.

The content in the refinitiv-data.custom.config.json file should be like this:

{
     "logs": {
    "level": "debug",
    "transports": {
      "console": {
        "enabled": false
      },
      "file": {
        "enabled": false,
        "name": "refinitiv-data-lib.log"
      }
    }
  },
    "sessions": {
        "default": "platform.my-custom-session",
        "platform": {
            "my-custom-session": {
                "app-key": "",
                "realtime-distribution-system": {
                    "url" : "<hostname>:15000",
                    "dacs" : {
                        "username" : "<username>",
                        "application-id" : 256,
                        "position" : ""
                    }
                }
            }
        }
    }
}

The server must be configured to support WebSocket connections.

Then, refer to the example on GitHub.

stream = rd.open_pricing_stream(
    universe=['JPY='],
    service="ABC_SELECTFEED",
    fields=['BID', 'ASK'],
    on_data=display_data
)

You can enable the file logging in the configuration file to troubleshoot the problem.
