# Beneficiary Account Verifications (BAV)
Verify that the bank details of your beneficiary are valid before sending a payout.
__Authentication header__
```
Authorization: {your_credentials}
WP-Api-Version: 2025-01-01
```
Replace `{your_credentials}` with your base64-encoded Basic Auth username and password given to you by your Implementation Manager.
You **must** use the `Authorization` header for any request you send to our Beneficiary Account Verifications API, unless you are using client certificate [authenticating with SSL/TLS](/products/reference/security).
__DNS whitelisting__
Whitelist the following URLs:
* `https://try.access.worldpay-bsh.securedataplatform.com/`
* `https://access.worldpay-bsh.securedataplatform.com/`
Please ensure you use DNS whitelisting, not explicit IP whitelisting. When you make a request within Access Worldpay, you should always cache the response returned.
