  title: Salla Shipment Lifecycle
  summary: Resolve a courier, create a shipment, read it back, and branch on whether to cancel.
  description: >-
    The end-to-end courier flow for a Salla shipping app. The available
    shipping companies are listed, a shipment is created against an order with
    the chosen courier, the created shipment is read back to capture its
    tracking detail, and the flow branches on a caller flag to cancel the
    shipment when it should not proceed. Each step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
