HistoricalBulkSearch API - Need Help in Python

SamGarcia

Hi Team,

We would like to ask for your expertise in coding for Python since this what the client uses.
Here is the REST API JSON Format that we are more familiar with:

POST
https://selectapi.datascope.refinitiv.com/RestApi/v1/Search/HistoricalBulkSearch

 {
    "Request": {
    "Identifiers": [
        {
            "Identifier": "GB00BH4HKS39",
            "IdentifierType": "Isin",
            "Exchange": "GTX"
        },
        {
            "Identifier": "GB00BH4HKS39",
            "IdentifierType": "Isin",
            "Exchange": "TDG"
        }
    ],
    "Range": {
        "Start": "2025-11-24T00:00:00.000Z",
        "End": "2025-11-24T00:00:00.000Z"
    }
    }
}

Here is the client verbatim and I don't know if this will help:
I’m not sure how to access and execute the API code you mentioned, I tried to download the API

$ uv add refinitiv-data

but wasn’t able (tried on windows, linux) with 3 different python environment (might try again with something stand alone)

Hello @SamGarcia

Please be informed that the API is https://developers.lseg.com/en/api-catalog/datascope-select/datascope-select-rest-api which cannot be accessed via https://developers.lseg.com/en/api-catalog/lseg-data-platform/lseg-data-library-for-python . The refinitiv-data (Data Library version 1) and lseg-data (Data Library version 2) cannot access and use the DSS REST API.

The client can use Python requests library to

1. Request token to https://selectapi.datascope.refinitiv.com/RestApi/v1/Authentication/RequestToken endpoint with DSS Username and DSS Password (not Workspace or RDC credential)
2. Once get a token, send it to https://selectapi.datascope.refinitiv.com/RestApi/v1/Search/HistoricalBulkSearch endpoint with HTTP Header "Authorization: Token {token}"

HistoricalBulkSearch example code:

history_search_url= 'https://selectapi.datascope.refinitiv.com/RestApi/v1/Search/HistoricalBulkSearch'


payload = json.dumps({

  'Request': {

    'Identifiers': [

      {

        'Identifier': 'GB00BH4HKS39',

        'IdentifierType': 'Isin',

        'Exchange': 'GTX'

      },

      {

        'Identifier': 'GB00BH4HKS39',

        'IdentifierType': 'Isin',

        'Exchange': 'TDG'

      }

    ],

    'Range': {

      'Start': '2025-11-24T00:00:00.000Z',

      'End': '2025-11-24T00:00:00.000Z'

    }

  }

})

headers = {

  'Content-Type': 'application/json',

  'Authorization': f'Token {token}'

}


try:

    history_response = requests.request('POST', history_search_url, headers=headers, data=payload,timeout=50)

except requests.exceptions.RequestException as exp:

    print(f'Caught exception: {exp}')


if history_response.status_code == 200:  # HTTP Status 'OK'

    print('Request succeed')


    print(f'Response = \n{history_response.json()}')


if history_response.status_code != 200:

    print(f'RDP authentication failure: {history_response.status_code} {history_response.reason}')

    print(f'Text: {history_response.text}')
