  title: Paystack Settlement Reconciliation
  summary: Fetch settlement records, then list the transactions that make up a chosen settlement payout.
  description: >-
    The payout reconciliation flow. Settlement records are fetched to identify a
    settlement payout, and the underlying transactions that comprise that
    settlement are then listed so each payout to the bank account can be tied back
    to its source transactions. The settlement id is supplied as an input because
    it identifies which settlement to drill into. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
