  title: Flutterwave Order Checkout And Verify
  summary: Create a customer, place a server-side order for them, then retrieve the order to confirm its status.
  description: >-
    A server-side checkout pattern. The workflow creates the customer, creates
    an order that captures the cart amount and line items, and retrieves the
    order to confirm it was recorded and inspect its status. This backs a hosted
    checkout session where the order object is the source of truth for what the
    customer is paying for. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
