# POST /v1/borderless-accounts/{}/conversions is deprecated

Transferwise deprecated POST /v1/borderless-accounts/{}/conversions without giving a shutdown date yet.

Transferwise has deprecated the POST /v1/borderless-accounts/{}/conversions endpoint without announcing a shutdown date. Subsequent calls to this endpoint will fail. The change affects all integrations relying on the legacy borderless accounts conversion route.

## What to use instead

Convert between balances with POST /v2/profiles/{profileId}/balance-movements instead.
