Connect to the live update stream

Opens a WebSocket that streams order_updated events for your organization. Authenticate with a token from POST /ramp/ws-api-token passed as the token query parameter; a browser cannot set an Authorization header on a WebSocket upgrade. The token is single-use and expires in 30 seconds. Each frame signals that an order changed; re-read the order with GET /ramp/order/{order_id} for the authoritative state, including any pending approval package. Connect over wss (for example wss://api.etherfuse.com/ramp/ws?token=...).
