# Exchange callbacks

> Sent to your callback URL whenever the status of an exchange created via [/v2/exchange/fixed](/api-reference/endpoints/exchange-fixed) or [/v2/exchange/now](/api-reference/endpoints/exchange-now) changes. The format is the same for both endpoints.

When you receive a callback with `"status": "confirmed"`, the exchange has been successfully completed. At this stage, your balances for the affected currencies have already been updated. You can retrieve your current account balances via the [/v2/accounts/list](https://docs.ca.cryptoprocessing.com/api-reference/endpoints/accounts-list.md) endpoint.
