# TRANSACTION_REVERSED

> Fired when a transaction is reversed or a merchant refund is received. Funds are returned to the card.

<Warning>
  **Deprecated** — superseded by [`TRANSACTION_PROCESSED`](/v3.20/webhooks/events/transaction-processed)
  (`status: REVERSED`). Still delivered to existing subscribers, so no migration is
  required. New integrations should subscribe to `TRANSACTION_PROCESSED`.
</Warning>

Fires when a card transaction is reversed. This covers two scenarios:

* **Pre-settlement reversal**: An authorization is voided before it clears — the reserved funds are released back to the card.
* **Post-settlement refund**: A merchant issues a refund after the transaction has cleared — funds are credited back to the card.
