};
Hydrate a front-end session with a member’s session tokens from your backend. If you log a member 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. Then, make a Session Authenticate call to authenticate the session tokens and retrieve the user’s current session.

​
Parameters

An object containing the session tokens to update the front-end session.
