Update a user's session tokens to hydrate a front-end session from the backend. For example, if you log your users in with one of our backend SDKs, you can pass the resulting session_token and session_jwt to this method to prime the frontend SDK with a valid set of tokens. You must then make an authenticate call to authenticate the session tokens and retrieve the user's current session.
