  title: Interswitch Transaction Reconciliation
  summary: Find a transaction by merchant reference, then pull its full detail for reconciliation.
  description: >-
    Back-office reconciliation flow over the Transaction Search API. The workflow
    locates a transaction by its merchant reference, then — when a match is found
    — pulls the full transaction detail (status, response code, settlement date,
    masked PAN) for settlement reconciliation. It branches on whether the
    reference search returned any transactions. All requests are
    Bearer-authenticated.
