  title: Amazon Connect Start Chat Contact and Set Attributes
  summary: Start a customer chat, confirm the contact, and attach routing attributes.
  description: >-
    Initiates a customer chat against a contact flow and prepares it for routing.
    The workflow starts the chat contact, reads the contact back to confirm it is
    live, and writes user-defined attributes onto the contact so the flow can
    branch on customer context such as tier or topic. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
