When creating transactions on behalf of a buyer via a server
without the use of Embed, pass the IP address of the buyer via
the X-Forwarded-For header.
Most of the SDKs support passing through this header on the POST transactions call.
This header is automatically accepted and passed to the payment service
where needed. If the header is not provided and the service provider recommends passing the IP
address, the IP address of the request’s origin is forwarded instead.
Not all endpoints pass the IP address to a connector. It is recommended
to send the IP address whenever it is available.
