  title: Commerce Layer Guest Order Add Line Item and Place
  summary: Open a guest order, add a SKU line item, then place the order in one flow.
  description: >-
    A streamlined Commerce Layer guest checkout flow. The workflow opens a guest
    order in a market with a customer email, adds a SKU line item, and then
    patches the order with the documented _place transition flag to submit it.
    Every step spells out its JSON:API request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
