Set proxy header from upstream

I'm configuring an application that will authenticate a user, and then set the X-Accel-Redirect header and a private api key, Foo (for testing purposes), that will be passed on to the proxied endpoint.

I'm setting the private api key as a header in the authenticating application, and have the following location block in my nginx configuration file. How do I set the header to the proxied application based on what the upsteam server sets? I've also tried using $http_foo and $sent_http_foo. Currently, the Foo response header is never set for the proxy.

location ~* ^/redirect {
  internal;

  resolver 8.8.8.8;
  proxy_ssl_server_name on;
  add_header Foo $upstream_http_foo;

  set $my_host "requestb.in";
  set $my_uri "a_test_uri";
  proxy_pass http://$my_host/$my_uri;
}

The directive to use is proxy_set_header, so in your case:

proxy_set_header Foo $http_api_key; # assuming a "API-Key" header incoming

As a general rule, any settings you intend to apply to your communication with an upstream will be prefixed with proxy_
