# Card Transactions
> List transaction history for a specific card. GET /cards/{id}/transactions. Requires cards:read scope.
## Overview
Returns a paginated list of card-level transactions sourced directly from the card network. This includes purchases, declines, refunds, reversals, and fees — everything that moved money on the physical card.
These are **card-to-merchant transactions**, not program ledger movements. For deposits, withdrawals, and card funding/unload events, use `GET /transactions` instead.
