I fail to use the get_data function. I installed the DatastreamPy via pip with my proxy.
Looking into the DS_response file, I duly get the connection and get a token but the request output is "None".
Checked also in your test page https://developers.refinitiv.com/en/api-catalog/eikon/datastream-web-service to do a request but get the message that my access is suspended... But still I can use Datastream requests in XLS with no pb.
Any hint ?
