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}
Accept: application/vnd.worldpay.foreignexchange-v1+json
Content-Type: application/vnd.worldpay.foreignexchange-v1+json
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.
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.
AcceptWe use the Accept header to identify which version of the resource you are using. You must use the Accept header if the HTTP method is a GET.

If you're using both the Content-Type and Accept 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.

DNS whitelisting

Whitelist the following URLs:

  • https://try.access.worldpay.com/
  • https://access.worldpay.com/

Please ensure you use DNS whitelisting not explicit IP whitelisting.

Note

When you make a request within Access Worldpay, you should always cache the response returned.
