  title: Swell Onboard Customer and Place Order
  summary: Create a customer account and immediately place an order for that account.
  description: >-
    A core back-office flow for headless commerce. The workflow creates a
    customer account from an email and name, captures the new account id, and
    then creates an order tied to that account with line items and a currency.
    Each step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
