Capture POST and redirect with POST data to client

[heymartinadams]

Might anyone know how it’s possible to capture form POST data on a serverless function and then reroute that incoming request to the client?

In order to implement “Sign in with Apple”, I need to capture the form POST data on a server and reroute it to my client. See here (at bottom).

However, not sure if a serverless API endpoint has that ability. Noticed a similar, related issue with NextJS: vercel/next.js#7074

Looks like I can redirect like this:

res.writeHead(302, 'Redirect', { Location: url })
res.end()
