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.
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.
