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, 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.

{
  "event":       "CARD_TERMINATION_REFUND_POST",
  "eventId":     "evt_01HXY7890XYZABCDE",
  "businessId":  "BUS1A2B3C4D5E6F",

    "cardholderId": "chd_01HXYZ1111ABCDEF0000",
    "amount":       4.25,
    "currency":     "USD",

  }
}

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

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