Php curl redirect from another page?

Question

PHP

In general, there is a site X
AND there is a request path X/api

You need to send a request to X/api
AND the user is on the X/ page (because it is redirected according to the parameters of those who came from X/api using js with X/).

How to solve this?
You can use JS (but api does not come with a link for a redirect, other parameters come with api for a post request when redirecting)

The access itself (there is no X site to change files!)

Answer 1
