DSWS REST API

I'm attaching a screenshot but also here's the full details of the issue as well:


We're using the DSWS REST API. While trying to troubleshoot in case it was some of our code causing the issue, we tried multiple alternatives.

We tried the Python package https://github.com/datastreamapi/DatastreamPy as mentioned on https://developers.lseg.com/en/api-catalog/eikon/datastream-web-service, without any luck, resulting in the same error.

We also tried pure manual HTTPS requests to the same REST API specifically
1. Get auth token: https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/Token?username=...&password=...

2. Get data using the above auth token https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/Data?token=...&instrument=VOD&datatypes=PL%2cPH&datekind=TimeSeries&start=-30D&end=-25D&freq=D

The (1) auth token is returned successfully (HTTP code 200), but (2) fails to return the data and instead returns HTTP code 401 with the following response:

{
"Code": "InvalidCredentials",
"Message": "User ZEID052 access temporarily suspended. Access suspended whilst investigating end user . Please contact your LSEG representative",
"SubCode": null
}


and some headers of a sample problematic reponse:

X-Ds-Server: DSWP12

X-DS-VIP: DS_Web_Prod_EXT-443

    Hi @RALPHPAOLO.NAVARRO , may I ask: which data field were you after? I'm asking because on my end I can make things like this work:


    import DatastreamPy as DSWS

    # We can use our Datastream Web Socket (DSWS) API keys that allows us to be identified by
    # Refinitiv's back-end services and enables us to request (and fetch) data:
    # Credentials are placed in a text file so that it may be used in this code without showing it itself.
    (DSWS_username, DSWS_password) = (
        open("Datastream_username.txt","r"),
        open("Datastream_password.txt","r"))

    ds = DSWS.Datastream(
        username = str(DSWS_username.read()),
        password = str(DSWS_password.read()))

    # It is best to close the files we opened in order to make sure that we don't stop any other
    # services/programs from accessing them if they need to.
    DSWS_username.close()
    DSWS_password.close()


    # # Alternatively one can use the following:
    # import getpass
    # dsusername = input()
    # dspassword = getpass.getpass()
    # ds = DSWS.Datastream(username = dsusername, password = dspassword)

    df = ds.get_data(
        "VOD",
        ['PL'],
        start = '2013-08-31',
        kind = 1)
