# Confirm Sub-Account Withdrawal

`POST /api/v4/sub-account/withdraw/confirm`

The endpoint confirms a single withdrawal transaction created by a [sub-account](/glossary#sub-account)
of the authenticated main account. Confirmation is the main account action that approves a withdrawal
held in `unconfirmed_by_main_account` status and releases it for processing.

Identify the target transaction by its external id, obtained from
[List Unconfirmed Sub-Account Withdrawals](/api-reference/sub-accounts/list-unconfirmed-sub-account-withdrawals).
Confirmation is the only main account action on an unconfirmed withdrawal; a withdrawal left unconfirmed
expires after a retention period. A successful call returns an empty object.

<Note>
The sub-account withdrawal endpoints are not available by default. To request access, contact institutional@whitebit.com.
A `404 Not Found` response indicates the endpoint is not enabled for the account.
</Note>

<Note>
The sub-account feature must be enabled for the region.
