Can a VPN be used only for certain server-to-server requests?

Question

PHP

There is a server with a website. And there is a task to connect to the api of a third-party resource, access to which is provided only via VPN. How can you give site users access to this third-party resource? Is this a typical situation or is the approach itself bad initially?

Answer 1

The situation is typical. In routing, you specify that all requests to the necessary private IP/domains go through the VPN.
On the site, accordingly, you make a wrapper that proxies user requests.
