  title: Teradata Provision a Cross-System Link
  summary: Register a system, create a connector for it, then link it into a fabric.
  description: >-
    Builds the QueryGrid plumbing that lets two systems exchange data. The
    workflow registers a new system, creates a connector that QueryGrid uses to
    talk to it, and then creates a link that joins that connector to an existing
    target connector inside a fabric. Each step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
