  • SECURELY PRESERVING PRIOR SECURITY TOKENS FOR RECALL
    Publication number: 20230188515
    Abstract: An approach for optimizing security token exchange. The approach receives a first request from a client. The approach extracts a first security token and an API reference. The approach validates the first security token. If the security token is valid, then the approach, calls the API and retrieves a second security token, embeds the second security token in the API and sends a second request with a third security token and the reference to the API to another application in a different domain.
