Hello @emine.arikan,

Some of the information on Funds, including Lipper funds, can be obtained via Entity Search ( DSS REST Reference Tree) and Fund Search (DSS REST API Reference Tree).

From my testing, I do not see LipperIDs populated as PreferredIdentifierType:

{
                {protocol}}{
                {host}}{
                {api}}Search/FundSearch
{
    "SearchRequest": {
        "DomicileCodes": null,
        "CurrencyCodes": null,
        "SubTypes": null,
        "IdentifierType": "Ric",
        "Identifier": "LP68233262",
        "PreferredIdentifierType": "LipperID"
    }

}

Results in:

{
    "@odata.context": "https://selectapi.datascope.refinitiv.com/RestApi/v1/$metadata#Collection(DataScope.Select.Api.Search.FundSearchResult)",
    "value": [
        {
            "Identifier": "LP68233262",
            "IdentifierType": "Ric",
            "Key": "VjF8MHgwMDAzZjgwODllNjhiZWJifE1GUVV8TFA2ODIzMzI2MnxSSUM",
            "Description": "Galaxy CSI Tencent Jian 100 A",
            "InstrumentType": "Fund",
            "FundName": "Galaxy CSI Tencent Jian 100 A",
            "FundAdministrator": "Galaxy Asset Management Co., Ltd.",
            "PortfolioManager": "Galaxy Asset Management Co., Ltd.",
            "DomicileCode": "CN",
            "CurrencyCode": "CNY",
            "InvestmentType": "Equity",
            "SubType": "MutualFund",
            "AssetStatus": "Active",
            "IssuerName": "",
            "IssuerOrgId": "171173"
        }
    ]
}

However, for authoritative answer on the best way to query, and the content being populated as well as your DSS ID permissioned for this content, I would suggest to contact Refinitiv DSS content experts via Refinitiv Helpdesk Online -> Content -> DSS, directly. Let us know if you are able to proceed?

From API integration viewpoint, Refinitiv Data Platform (RDP) offers HTTP REST request/response integration. It allows access to extensive funds information, including LipperID and several classifications. RDP Search is not released, it is currently in Limited Release/Beta.
