Authentication

IBKR authenticated web session cookie compound discovered

For the 3rd Party Web API, authenticate using IBKR's supported authorization flow and maintain the resulting session cookie jar. The published OpenAPI for the 3rd Party Web API uses cookieAuth security, and IBKR's OAuth guide states OAuth protocol parameters are sent in Authorization headers while subsequent protected-resource requests are signed/authorized using the established session materials. Start from the official API home at IBKR API Home and the OAuth guide at OAuth at Interactive Brokers.
