  title: SAP BRIM Authorize and Confirm a Charge Reservation
  summary: Reserve an amount against a prepaid balance, confirm it into a final charge, and read the balance.
  description: >-
    Runs the reserve-then-capture charging pattern on SAP BRIM Convergent
    Charging. The workflow authorizes (reserves) an amount against a prepaid
    balance, confirms the authorization to convert the reservation into a final
    charge, and reads the account balance to observe the result. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
