Version 2 OAuth Client Credentials with JWT requires a JWK public/private pair to be generated and registered with LSEG via the Platform Admin UI. The API will use a private JWK to create and sign a JWT request, which will be sent to retrieve an access token. The JWK will be handled by the API the exact same way as a client secret above. For more information about the Platform Admin UI, refer to the Real-Time — Optimized documentation in the LSEG Developers portal.
NOTE: Follow best practices for securely storing and retrieving JWK.
