ESG API : maximum number of instruments, duplicated headers and process for adding new fields

Hi,

I have a few questions regarding the ESG API:


1) Maximum number of items in a request:

We were told that the ESG API can handle maximum 100 companies per request. However, trying the request with more than 100 ISINs we still get all the data in the response and no restriction in the response. Can you please confirm the maximum number of requests per item ( i.e. Get Measures Full) and how item restriction works?


Example:

https://api.refinitiv.com/data/environmental-social-governance/{ {RDP_VERSION_ESG}}/views/measures-full?universe=4295533401,4295613014,4295641240, 4295856018, 4295856019, 4295856020, 4295856021, 4295856025, 4295856026, 4295856029, 4295856031, 4295856039, 4295856043, 4295856044, 4295856050, 4295856051, 4295856053, 4295856055, 4295856058, 4295856060, 4295856061, 4295856067, 4295856070, 4295856073, 4295856074, 4295856077, 4295856080, 4295856082, 4295856083, 4295856084, 4295856086, 4295856087, 4295856094, 4295856097, 4295856098, 4295856099, 4295856108,4295856110, 4295856118, 4295856121, 4295856122, 4295856134, 4295856136, 4295856137, 4295856141, 4295856150, 4295856152, 4295856154, 4295856167, 4295856169, 4295856173, 4295856174, 4295856181, 4295856189, 4295856196, 4295856216, 4295856220, 4295856223, 4295856234, 4295856246, 4295856249, 4295856256, 4295856257, 4295856266, 4295856267, 4295856276, 4295856277, 4295856281, 4295856305, 4295856309, 4295856316, 4295856333, 4295856338, 4295856343, 4295856351, 4295856352, 4295856360, 4295856396, 4295856400, 4295856422, 4295856428, 4295856431, 4295856433, 4295856435, 4295856441, 4295856449, 4295856451, 4295856461, 4295856463, 4295856474, 4295856486, 4295856489, 4295856495, 4295856496, 4295856504, 4295856533, 4295856537, 4295856539,4295856542,4295856544,4295856551,4295856573,4295856578,4295856585 &format=noMessages&start=0&end=0



2) Duplication of "description" field in the Header session:

In the response of GetScores and GetMeasures calls, the fields in the "Header" have always a duplicated "Description" item? See below. Is this a bug? Are you planning to fix it anytime soon?

headers": [

{

"name": "instrument",

"title": "Instrument",

"type": "string",

"description": "The requested Instrument as defined by the user.",

"description": "The requested Instrument as defined by the user."

},

{

"name": "periodenddate",

"title": "Period End Date",

"type": "date",

"description": "The last day of the financial period in question.",

"description": "The last day of the financial period in question."

},

{

"name": "TR.TRESGCScore",

"title": "ESG Combined Score",

"type": "number",

"decimalChar": ".",

"description": "Thomson Reuters ESG Combined Score is an overall company score based on the reported information in the environmental, social and corporate governance pillars (ESG Score) with an ESG Controversies overlay.",

"description": "Thomson Reuters ESG Combined Score is an overall company score based on the reported information in the environmental, social and corporate governance pillars (ESG Score) with an ESG Controversies overlay."

},


Example requests:

https://api.refinitiv.com/data/environmental-social-governance/{ {RDP_VERSION_ESG}}/views/scores-standard?universe=NESN.S https://api.refinitiv.com/data/environmental-social-governance/

{ {RDP_VERSION_ESG}}/views/scores-full?universe=NESN.S&format=noMessages



3) How are new Measures added in the API?

In the last years Refinitiv has increased the number of measures covered by the below call. Can youplease clarify how new measures are added? <Are any new measures added as a Header at the bottom of previous existing Headers/measures? How are these new entries communicated to users of RDP?

https://api.refinitiv.com/data/environmental-social-governance/{ {RDP_VERSION_ESG}}/views/measures-full?universe=NESN.S&format=noMessages


Thanks,

Carlos

Hi,

I'm able to see the duplicate description on the API DOCS using the Firefox Developer Tools. The API DOCS likely remove the duplicate description.

Hi @carlos.feres3,

#2: I don't see repeated description in the response message headers for any scores/measures endpoint. Can you please verify that it is not a bug in the code. You could also try python ESG sample provided in the downloads.


  "headers": [
    {
      "name": "instrument",
      "title": "Instrument",
      "type": "string",
      "description": "The requested Instrument as defined by the user."
    },
    {
      "name": "periodenddate",
      "title": "Period End Date",
      "type": "date",
      "description": "The last day of the financial period in question."
    },
    {
      "name": "TR.TRESGCScore",
      "title": "ESG Combined Score",
      "type": "number",
      "decimalChar": ".",
      "description": "Thomson Reuters ESG Combined Score is an overall company score based on the reported information in the environmental, social and corporate governance pillars (ESG Score) with an ESG Controversies overlay."
    },


For #1, and #3, please raise a ticket at Refinitiv Support to talk to a content/product expect. We can only answer technical questions on these forums.

Hi Gurpreet,

we are not yet using the response in any code. This is simply what we get in Postman with a collection we imported from the Developpers Portal:


I disagree that points #1 and #3 are content questions. I am afraid if I raised these questions via your normal support, I will get replies related to the Eikon terminal ( as usual) while my concerning is specific to the calls in RDP platform.

I still don't see duplicated description in the header. I have tried both Postman and the ApiDocs. Do you see the same result in the ApiDocs too?

Hi Gurpreet,

In the APIDocs I see only one item for "Description", however calling the API from Postman or our WebService we receive it always duplicated. Is this related maybe to our API account setup? Maybe the second description is supposed to be for another language, and as there’s none, it just repeats English as a fallback. Can you please check that?

Thanks,

Carlos

For #1 and #3, from Refinitiv support, select - Product Support -> I need help understanding content within the product, and select Elektron Data Platform - Environmental, Social & Governance as the product. This should help get to the right content group.

Hi Carlos,

As far as I know, the description is provided in English only. The data is exactly same in the APIDocs as the webservice (it is invoking the REST API underneath). Could you try the latest version of Postman, or try the esgViews.py sample from the downloads tab - Python tutorials source code. Uncomment the line to view the raw JSON response message:

#print(json.dumps(vData, indent=2))

We dont develop in Python. I have updated Postman to the latest version and I still see duplicated "Description" fields. We get the same when we call the API directly from our application. Can anyone check if the setup of our account is the reason for that? Thanks.

Carlos

Hi @carlos.feres3,

We have not been able to replicate your issue -either with API or with Postman tool. Moreover, you also do not observe duplicate fields when using APIDocs. This leaves us with two possibilities - either your API version is incorrect, or it is a user error.

Can you confirm that your RDP_VERSION_ESG is v1.

You can use Fiddler proxy to capture the raw REST messages to confirm that there are indeed no duplicated fields. See the setup guide here.
