  title: Moniepoint Pay A Bill
  summary: List billers for a category, validate the customer, process the bill, then poll the bill status.
  description: >-
    Pay a utility, airtime, or cable-TV bill through the Unified Biller Service.
    This workflow lists the billers in a category to resolve a billerCode,
    validates the customer identifier against the biller and item, processes the
    bill payment, and then polls the bill status until it reaches a terminal
    state of SUCCESS or FAILED. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
