OAuth 1.0aLive Session Token

Endpoint

|View as Markdown|Open in Claude|

The live session token will allow the user to access their API, for trading or for portfolio access, over a 24 hour period. The creation of the Live Session Token does not establish a complete trading session, as that would be handled by Initializing the Brokerage Session.

POST /oauth/live_session_token
