  title: Moniepoint POS Push Payment
  summary: Push a payment request to a Moniepoint POS terminal, then poll the terminal until the customer completes it.
  description: >-
    ISV partners push an authenticated payment request to a registered
    Moniepoint POS terminal and wait for the customer to tap to pay. This
    workflow pushes a payment request to a terminal serial number to obtain a
    reference, then polls the push-payment status until the terminal reaches a
    terminal state of COMPLETED, DECLINED, EXPIRED, or FAILED. Authentication is
    HTTP Basic using the API client id and client secret issued from the
    Moniepoint Business dashboard, applied by the runtime per the spec's
    security requirement. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
