Get started

Make yourself familiar with our API Principles to ensure a resilient integration.


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/vnd.worldpay.accounts.transfers-v1+json
Accept: application/vnd.worldpay.accounts.transfers-v1+json
HeaderDescription
WP-CallerId and/or X-WP-Diagnostics-CorrelationIdID of the consumer. This value is optional and provided by you. It should be unique per each consumer. If both WP-CallerId and X-WP-Diagnostics-CallerId are included in the request, then WP-CallerId is used. If not provided, it is generated, since it is required for traceability.
WP-CorrelationId and/or X-WP-Diagnostics-CorrelationIdID of the request which may be used between you, the API and downstream services. If both WP-CorrelationId and X-WP-Diagnostics-CorrelationId are included in the request, then we use WP-CorrelationId. If not set in either WP-CorrelationId nor X-WP-Diagnostics-CorrelationId, a new correlationId is generated, since the correlationId is required for traceability.
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 Account APIs, 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.
AcceptWe use the Accept header to identify which version of our API you are using. You must use the Accept header for any request you send to our Account APIs.

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.
