  title: Cellulant Get Bill and Pay
  summary: Fetch the outstanding bill for an account, then settle it with a Beep payout.
  description: >-
    A bill-payment flow for billers such as DSTV, GOTV, electricity, and water.
    The workflow first calls the Beep endpoint with BEEP.getBill to look up the
    outstanding amount for an account or invoice, then calls the same endpoint
    with BEEP.postPayment to settle the bill. Both steps use the bare
    postPayment operationId and inline the Beep Basic Authorization header
    alongside the payload credentials. The invoiceNumber and amount fields carry
    the bill reference and settlement amount through the packet.
