  title: Grubhub Orders API
  description: >-
    The Grubhub Orders API allows partners to receive, manage, and update
    order statuses for restaurant orders placed through the Grubhub
    Marketplace. Partners can retrieve individual orders by UUID, list
    orders by status and date range, confirm orders with estimated wait
    times, and update order lifecycle states. New orders are primarily
    received through webhook subscriptions, with polling available as
    a fallback.
