> **The method ships in the `crm 26.2100.0` update and is not yet available on all Bitrix24 accounts.** If the method is not yet available on your Bitrix24 account, the API returns `422 METHOD_NOT_YET_AVAILABLE` — this means the update has not reached your account yet, not that the integration is broken.

## List advertising accounts
