  title: Tomorrow.io Saved Location Realtime and Forecast
  summary: Create a reusable saved location, then pull realtime conditions and a multi-day forecast for it.
  description: >-
    A foundational Tomorrow.io pattern that turns an ad-hoc coordinate into a
    durable, reusable location resource and immediately exercises it. The
    workflow creates a saved location, captures the returned locationId, fetches
    the current conditions for that location, and then retrieves a structured
    hourly and daily forecast for the same point. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Persist a location and chain realtime plus forecast retrieval against it.

    Creates a saved location from a GeoJSON point, then uses the persisted
    locationId to fetch realtime conditions and a forecast in a single linear
    flow.
