  title: Paystack Initiate and Monitor a Bulk Charge
  summary: Initiate a bulk charge batch against saved authorizations, fetch the batch, then list the charges in the batch.
  description: >-
    The recurring batch-billing flow. A bulk charge batch is initiated against a
    list of saved card authorizations, the batch is fetched to read its status and
    totals, and the individual charges in the batch are listed so per-customer
    outcomes can be reconciled. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
