How to get all instruments by API request for a list created manually in DSS (not a count as ment...

@stas.grinberg,

If I understand correctly, you want to use the API to retrieve the list of instruments in an instrument list stored on the server.

For this you need the instrument list ID.

Step 1: get the instrument list ID from the instrument list name

If you only have the list name, you can retrieve the ID using the GetByName call:

GET https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/InstrumentListGetByName(ListName='MyListName')

This delivers the ListId:

{
"@odata.context": "https://hosted.datascopeapi.reuters.com/RestApi/v1/$metadata#InstrumentLists/$entity",
"ListId": "0x066c72ea4b60201a",
"Name": "MyListName",
"Count": 2,
"Created": "2018-10-03T16:59:07.670Z",
"Modified": "2018-10-03T16:59:29.986Z"
}

Step 2: get all instruments in the instrument list stored on the server

You can use the GetAllInstruments call (replace the InstrumentList Id value by the ID of your own list):

GET https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/InstrumentLists(';0x066c72ea4b60201a')/ThomsonReuters.Dss.Api.Extractions.InstrumentListGetAllInstruments

The result will contain a set of records, one per instrument. Each record contains the Identifier, IdentifierType, etc. Here is an extract of a sample output:

{
"@odata.context": "https://hosted.datascopeapi.reuters.com/RestApi/v1/$metadata#InstrumentListItems",
"value": [
{
"ListId": "0x066c72ea4b60201a",
"Identifier": "SARON.S",
"IdentifierType": "Ric",
"Source": "SWX",
"UserDefinedIdentifier": "",
"UserDefinedIdentifier2": "",
"UserDefinedIdentifier3": "",
"UserDefinedIdentifier4": "",
"UserDefinedIdentifier5": "",
"UserDefinedIdentifier6": "",
"Order": 4,
"Description": "SARON Swiss Average Rate ON",
"InstrumentListItemKey": "VjF8MHgwNjZjNzJlYTRiNjAyMDFhfDQ",
"InstrumentKey": "VjF8MHgwMDEwMGIwMDAzN2Y5YjhhfDB4MDAxMDBiMDAwZjVkYWIxMnxTV1h8TU5RVXxNT05ZfE1PTll8WXx8U0FST04uU3wzNjk4"
},

]
}
