Refinitiv Data Library for .NET with CIAM

We are currently using the Refinitiv Data Library for .NET for streaming data. Authentication is performed using ApplicationKey, MachineID, and Password. The login process is outlined at https://github.com/LSEG-API-Samples/Example.DataLibrary.DotNet, as follows:

"rdpSession": {

"rdp-credentials": {

"app-key": "<Application Key>",

"password-grant": {

"machine-id": "<RDP Machine ID>",

"password": "<RDP Password>"

}

Like in the example, we use the Refinitiv.Data nuget package.

We need to transition to using Customer Identity and Access Management (CIAM) for authentication.

Could you please inform us what changes are necessary in the settings or application to operate with this new type of login? I should have the Service ID and Password available; what modifications need to be made to the application?

Thank you.

Hi @nerusilj,

Your code looks correct and the library is responding correctly based on the discovery results. This is because your ID does not grant you permissions to retrieve any streaming URLs thus can’t connect to any streaming servers. As I mentioned before, you have to report that ID given to you is not properly setup to permission for streaming market data.

Hi @nerusilj

To support v2 authentication (CIAM), these are the necessary changes.

Via code:

var credentials = new ClientCredentials().ClientID(<ciam id>)
                                         .ClientSecret(<ciam passwd>);
var session = PlatformSession.Definition().OAuthGrantType(credentials)
                                          .GetSession();
var session.Open();

Via configuration:

"rdp-credentials": 
    "client-credentials": {
       "client-id": "<ciam id>",
       "client-secret": "<ciam passwd>"
    }
}

Thanks for the advice.

The connection was successful.

Now I have a problem with permissions.

I assume this is not a connection issue but a matter of account settings.

Hi @nerusilj

The message that refers to "/streaming/pricing/v1/..." indicates you do not have permissions to access streaming market data for your new ID. This is a little surprising given the CIAM IDs should be specifically targeted for only streaming market data. So you may need to confirm what specifically the ID provided to you is supposed to be permissioned for.

Hello,

I still have a isues with the implementation of streaming services in my code and would appreciate your assistance to review and identify the problem. Here is the code where I am setting up the client credentials and initiating the stream:

var credentials = new ClientCredentials()
           .ClientID(<ciam id>)
           .ClientSecret(<ciam passwd>);
        
var session = PlatformSession.Definition().OAuthGrantType(credentials)
            .GetSession();
        
session.Open();
        
var stream = OMMStream.Definition("GBP=")
            .Fields("ASK", "BID")
            .GetStream(session)
            .OnRefresh((item, msg, _) => Console.WriteLine(msg))
            .OnUpdate((item, msg, _) => Console.WriteLine(msg))
            .OnError((item, err, _) => Console.WriteLine(err))
            .OnStatus((item, msg, _) => Console.WriteLine(msg));
            
stream.Open();

Session opening is fine, but I receive an error when attempting to open the stream:

{
    Error: "Failed to open OMM stream - streaming services are unavailable. Verify log details and ensure you have permissions."
}

Here is the complete log:
