Using get_data() on an API (Not Codebook)

I'm trying to switch on an API, but it seems like the codes i was using in the internal Refinitv codebook app (even simple lines like:

import refinitiv.data as rd
import refinitiv.data as rd
rd.open_session()
df = rd.get_data(
universe = ['AAPL.O'],
fields = ['CF_CLOSE']
)

display(df)

) don't seem to work in the API. Do you if the structure of the call changes in an API ?

Thank you !

Bests,

Victor

Thank you for reaching out to us.

You can enable the debug log in the API by using the following code in order to verify what the problem is.

import refinitiv.data as rd

config = rd.get_config()

config.set_param("logs.transports.file.enabled", True)

config.set_param("logs.transports.file.name", "lseg-data-lib.log")

config.set_param("logs.level", "debug")


rd.open_session()

df = rd.get_data(

  universe = ['AAPL.O'],

  fields = ['CF_CLOSE']

  )


display(df)

With this code, the lseg-data-lib.log file will be created.

Please ensure all private information is removed from the file before sharing it

It looks like that the library can't connect to the desktop session.

Please refer to the Eikon Data API and Refinitiv Data Library - Troubleshooting article to make sure that the Data API Proxy is running properly.
