I'm trying to use to the the GetChain and GetChainComponents Operations, but the documentation is not available for these 2 calls.
Can someone provide me with the Endpoint, Body, and Headers for these calls? Thank you.
Hello @ovx-wxu
The RetrieveItem_Request_3 operation has "ExpandChains" attribute that lets the API returns the data for all RICs included in this particular chain RIC (e.g. 0#.DJI) in one response. Is it match your requirement?
{ "RetrieveItem_Request_3": { "ItemRequest": [{ "Fields": "", "RequestKey": [{ "Name": "0#.HSI", "NameType": "RIC" }], "ExpandChains": true, "Scope": "All" }] }}
Regarding the Get Chain and Get Chain Components operations, they are available in SOAP WebService protocol only which returns data as XML message . You can find more detail about them in the RKD API Quote Chains page.
Hi @ovx-wxu,
1. The GetChain and GetChainComponents are only available as legacy SOAP API and are not provided as REST API endpoint. Do you still need the SOAP envelope?
2. I will raise the missing documentation issue with the development team.
Hello @Gurpreet. , thank you for your reply again. Is there anything equivalent in JSON format? Where I can make a Chain call? As far as I see, GetSimpleData is the closest one.
If not, I would appreciate it if you can share the SOAP call with me. Thank you.
You can use RetrieveItem_Request_3 to get Chain data as well.
{ "RetrieveItem_Request_3": { "TrimResponse": false, "ItemRequest": [{ "Fields": "", "RequestKey ": [{ "Name": "0#.DJI", "NameType": "RIC" } ], "Scope": "All" } ] }}
See Section 16.6 for the Quote Chain documentation.
I don't think RetrieveItem_Request_3 returns all the RICs within a Chain, is there another call that returns all the details of all the RICs in the Chain? Thanks again.
If you think this is an issue with returned chain data, I would recommend that you raise a content support ticket with my.refinitiv.com and talk to content expert. They would be able to advise you on alternate API calls to use here.
