# CARD_TERMINATION_REFUND

> Fired when a terminated card's remaining balance is refunded back to your program.

Fires when a card is terminated and its remaining prefunded balance is returned to your program balance.

The `reference` is the provider transaction id — unique per refund — so use it as your idempotency key.

| `cardId`       | string | The terminated card ID                                                      |
| `cardholderId` | string | The cardholder the card belonged to                                         |
| `amount`       | number | Refunded amount, credited to your program balance                           |
| `currency`     | string | ISO-4217 currency of the refund                                             |
| `reference`    | string | Provider transaction id — unique per refund; use it as your idempotency key |
| `timestamp`    | string | ISO 8601 time the refund was processed                                      |

## Common Use Cases

* Reconcile the returned balance against your program ledger
* Log the refund for audit purposes, keyed on `reference`

<Note>
  Deduplicate on `reference`. A webhook retry re-delivers the same `reference`; a genuinely
  new refund always carries a new one.
</Note>
