Fired when money lands on an already-terminated card and is returned to your business wallet. 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. Each delivery carries a distinct reference (the provider transaction id) and is credited exactly once — always deduplicate on reference.
