Hello,

Our client is currently migrating to v2 authentication and is in process of testing the following RTO Java sample code:

websocket-api/Applications/Examples/RTO/java/MarketPriceRTOClientCredAuth.java at master · Refinitiv/websocket-api · GitHub

They are concerned that the MarketPriceRTOClientCredAuth.java posted on the website link above is incorrect specifically with the way it periodically re-authenticates.

They do not see a grant_type of refresh_token, and furthermore, the newly returned access_token from the HTTP authentication request is not being passed back into the web socket.

Can you please help?
Thank you

    Hello @dumitru.arama

    I checked the Java RTO example and did not find any discrepancies. There is no concept of periodic access token refresh when using Client Credentials, but if there is a connection loss, a valid token is required. This means the app has to re-authenticate if the token is expired. This is what is implemented in the code sample.

    They do not see a grant_type of refresh_token, and furthermore, the newly returned access_token from the HTTP authentication request is not being passed back into the web socket.

    There is no Refresh token when using client credentials.

    PS: There is an option to use RTSDK Java, which can handle all the discovery and session management tasks for the user. See this example on GitHub.

    Hello @dumitru.arama

    Please check an Getting Started with Version 2 Authentication for The Real-Time Optimized: Overview article for an in dept detail of the Version 2 authentication.

    The Version 2 does not use a refresh token anymore; it uses the same Client Credential grant request message for both the initial request and renewal of the access token.

    There is also a Real-Time WebSocket API: The Real-Time Optimized Version 2 Authentication Migration Guide article that might help you.
