Returns debit card transactions for the card from the General Ledger (Command.GeneralLedger.GLGetDebitCardTransactions). GL-201: Responses may include multiple ledger rows for one authorization when ION completes partial capture (settled amount less than hold), delta capture (additional amount over hold), or informational authorizations. Use optional debit_card.capture_mode, authorized_amount, captured_amount, and released_amount to explain amounts. Logical grouping uses a stable id (root transaction) across related rows.
