Session & Core
The ambient context every integration needs: where the session is in its lifecycle, the clock, the lap count, and the driver entry list. Use these to gate your timing logic and to label everything else —driver.list maps the driver numbers that key most other feeds.
Subscribe with the feedId via webhook or SSE. The badge shows the feed's access class: free feeds are open to every plan, live feeds require the Developer plan, and analytics feeds require the Custom plan.
