Set your headers

Setting your headers is an important part of an API request. The headers represent the meta-data associated with your API request.

Authorization: {your_credentials}
Content-Type: application/json
WP-Api-Version: 2023-06-01
HeaderDescription
AuthorizationWe use the Authorization header to identify and authenticate you within Access Worldpay. You -must- use the Authorization header for any request you send to our APM API, unless you are using client certificate authentication over TLS. If you must use this, read our reference guide on Authenticating with SSL/TLS.
Content-TypeWe require the Content-Type header if the request you're sending includes a request body, and if the HTTP method is a POST or a PUT.
WP-Api-VersionWe use the WP-Api-Version header to identify which version of our APM API you are using. You must use the WP-Api-Version header for any request you send to our API.

If you're using both the Content-Type and WP-Api-Version headers, they must match.

Note

Replace {your_credentials} with your base64-encoded Basic Auth username and password. To get your Access Worldpay credentials contact your Implementation Manager.
