-- in my HTML stuff:
function callback(resp){
                var msg = "";
                var status = "";

                switch(resp.status){
                        case 201:
                                $.ajax({
                                        type: 'POST',
                                        async: false,
                                        url: 'process.php?email='+load('mail')+'&cc='+resp.data.uri,
<truncated for brevity>

-- in PHP:
<?php
// Startup the Balanced API stuff
require(__DIR__ . '/vendor/autoload.php');

Httpful\Bootstrap::init();
Balanced\Bootstrap::init();

// Get the card URI
$uri = $_POST['cc']; // this now has the response.data.uri value
