  title: ServiceNow Create Trouble Ticket Then Update
  summary: Create a trouble ticket, read it back by id, then update its status and severity.
  description: >-
    The TM Forum-style trouble-ticket lifecycle exposed by ServiceNow over the
    Case, Incident, and Service Problem Case tables. The workflow creates a
    trouble ticket, retrieves it by its returned id to confirm persistence, and
    then updates its status and severity as the ticket progresses. Unlike the
    Table API, the Trouble Ticket API returns each ticket as a flat object
    keyed by id rather than wrapping it under a result object. Every request is
    written inline.
