# CARD_TERMINATION_REFUND_POST

> Fired when funds arrive on an already-terminated card and are refunded back to your program.

Fires when money lands on an **already-terminated** card and is returned to your program balance. This happens for:

* a later reconciliation/discrepancy refund from the provider, or
* a merchant refund that posts to a card after it was terminated.

Unlike [`CARD_TERMINATION_REFUND`](/v3.20/webhooks/events/card-termination-refund), this event can fire **multiple times** for the same card — once per incoming refund. Each delivery carries a distinct `reference` (the provider transaction id) and is credited exactly once.

## Payload Fields

| Field          | Type   | Description                                                                 |
| -------------- | ------ | --------------------------------------------------------------------------- |
| `cardId`       | string | The terminated card the refund posted to                                    |
| `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

* Capture merchant refunds that arrive after a card is terminated
* Reconcile discrepancy refunds against your program ledger

<Note>
  Always deduplicate on `reference`. Because this event can fire several times for one card,
  per-card deduplication would incorrectly drop legitimate later refunds.
</Note>
