Python API config.json

Hi,

I had an LSEG helpchat which instructed me to post my question here (Ticket#15530419).

I am usually using the Refinitiv GUI dashboard, but am trying to set up my Python API calls to fetch hourly FX and interest rate datasets.

I am following the Python Juypter Notebook provided by LESG here:
https://github.com/LSEG-API-Samples/Example.DataLibrary.Python/blob/lseg-data-examples/Quick%20Start/QS_1.0%20-%20Sessions.ipynb

And I am populating the config file from this template:

https://github.com/LSEG-API-Samples/Example.DataLibrary.Python/blob/lseg-data-examples/Configuration/lseg-data.config.json

Under "realtime-distribution-system", I do not know how to locate my "URL" (HOST:PORT) or "DACS ID"

Where can I find this information?

I'd believe authenticating with credentials is best because the LSEG desktop application is unable to be installed on the Python server running my financial models.

Here is the error message I am currently receiving:

Thank you for reaching out to us.

Please let know which LSEG product you are using (Datastream, Workspace, Data Platform, or RTDS).

The LSEG Data Library for Python can retrieve data from the Desktop Workspace, Data Platform, or RTDS depending on the configuration. The default session configuration on GitHub uses the Data Platform (platform.ldp).

"sessions": {

"default": "platform.ldp",

You can change it to "desktop.workspace" or "platform.deployed" to connect to the Workspace or RTDS respectively.

However, if you are using Datastream, you need to use the Datastream Web Service instead.
