  title: ServiceNow Order Catalog Item
  summary: Look up a catalog item, read its details, then order it immediately.
  description: >-
    The direct order-now path through the Service Catalog API. The workflow
    lists catalog items in a catalog to find a candidate, reads the chosen item
    by sys_id to confirm it is orderable, and then submits an immediate order
    for it with a quantity and variable values, returning the request number.
    The Service Catalog API wraps each item and the order result under a result
    object. Every request is written inline.
