One integrationQuery work zones from many publishers through a single API instead of building a separate feed integration for each.
Know the sourceEvery record carries its publisher, freshness and quality indicators, and scheduled activity stays distinct from confirmed activity.
Standard formatsReceive WZDx 4.2 or CWZ-compatible 1.0, so your existing tooling works unchanged.
