Authentication Set your headers
Authorization: {your_credentials} Content-Type: application/json WP-Api-Version: 2024-07-01
Replace {your_credentials}
with your base64-encoded Basic Auth username and password given to you by your Implementation Manager.
You must use the Authorization

DNS Whitelisting
Whitelist the following URLs:

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.
