  title: SAP BRIM Charge an Account and Refund It
  summary: Execute a charge against an account, refund that charge, and confirm the balance.
  description: >-
    Executes and then reverses a charge on SAP BRIM Convergent Charging. The
    workflow charges the account, refunds the charge it just created using the
    returned charge identifier, and reads the account balance to observe the
    restored funds. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
