  title: Flutterwave Virtual Account Collection
  summary: Create a customer, issue a dedicated virtual account for them, then verify the account is active.
  description: >-
    The pay-with-bank-transfer collection pattern. The workflow creates a
    customer, issues a virtual NUBAN tied to that customer for receiving bank
    transfers, and retrieves the virtual account to confirm it was provisioned
    with an account number and an active status. Branching on the account status
    lets the caller surface the account number to the payer or handle a
    provisioning delay. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
