  title: ServiceNow Link Configuration Item to Incident
  summary: Find a CI by name in a CMDB class, fetch its full record, then attach it to an incident.
  description: >-
    A CMDB-to-ITSM linking flow. The workflow lists configuration items in a
    CMDB class filtered by name, branches on whether a CI was found, fetches the
    matched CI's full record from the CMDB Instance API, and then patches an
    incident on the Table API to reference that CI as its affected
    configuration item. The CMDB Instance API returns lists and single CIs
    under a result object/array. Every request is written inline.
