Refinitiv .NET Library GrantRefreshToken returns unsupported

I am unable to authenticate a PlatformSession using the Refinitiv.Data libraries (v1.0.0-beta2) for .NET when trying to use GrantRefreshToken grant type.

session = PlatformSession.Definition().AppKey(appKey)
    .OAuthGrantType(new GrantRefreshToken().UserName(username).RefreshToken(refreshToken))
    .TakeSignonControl(true)
    .GetSession();

Response when trying to open a session using the above

{PlatformSession (Cloud)}
    [Refinitiv.Data.Core.PlatformSessionCore]: {PlatformSession (Cloud)}
    LastEventCode: SessionAuthenticationFailed
    LastEventMessage: {
  "ExceptionType": "System.NotSupportedException",
  "Message": "PlatformSession (Cloud) authorization using grant GrantRefreshToken 
  {\r\n\t\tUser: raymond.tieu@refinitiv.com\r\n\t\tRefresh Token: 914d1286-2bcb-4719-8bd8-c872bf3880ca\r\n\t} 
  not supported."
}
    OpenState: Closed

I have tried passing a refresh token obtained from https://sts.login.cp.thomsonreuters.net/oauth2/v1/token after getting the access/refresh tokens using my username and password.


I am able to authenticate a session when using the GrantPassword grant type. Is the GrantRefreshToken implemented in the .NET libraries?

@RaymondTieu1

RDP only supports the password grant authentication mechanism. In the near future, RDP will be supporting Client Credentials which will also support the self-signed client assertion. When these details are finalized, they will be supported within the Refinitiv Data Libraries (Python, TypeScript and .Net).

Hi @RaymondTieu1

You stated you found success when using the GrantPassword. Is there a reason you are not using this? What are you trying to achieve by using the GrantRefreshToken?

Currently I am authenticating using the PKCE authorization code flow and obtaining the tokens from AAA to then connect to RDP. I was hoping the .NET library would be able to allow authentication using the token from the AAA server so there would be no need to handle client usernames and passwords.
