What you want to do on the server side is generate an expiring session id that is sent back to the client on login or signup. without proxying the request. Finally, you add this signature as a parameter Get the API key and you have all the tools to access the API.

Informally, we call this process "signing the But even then one cannot easily refresh the CSRF validation cookie when a new token is requested, as users might be browsing the same site in multiple windows, sharing a single cookie (which, when refreshing, would be updated in all windows, after which the JavaScript token in the other windows would no longer match that single cookie). To determine where the data is shown, a public API key is used to limit access to domains we know, and above all to ensure the private user data is not vulnerable to CSRF.
