creating stripe connected subscriber account - php

Question

I'm trying to first create a stripe account, then create the subscription and customer via the created account ID, and then ultimately link the two to create a 'connected' subscriber account on stripe and for it to appear under my connected accounts in my dashboard. So far the script is failing.
// Include Stripe PHP library
require_once 'stripe-php/init.php';
// Set API key
\Stripe\Stripe::setApiKey($STRIPE_API_KEY);
// Create Account
try {
$stripe = \Stripe\Account::create(array(
"email" => $email,
"country" => "US",
"type" => "custom",
'capabilities' => [
'card_payments' => ['requested' => true],
'transfers' => ['requested' => true],
],
));
// Add customer to stripe
try {
$customer = \Stripe\Customer::create(array(
"email" => $email,
"source" => $token
), array("stripe_account" => $stripe->id));
}catch(Exception $e) {
$api_error = $e->getMessage();
}
if(empty($api_error) && $customer){
// Convert price to cents
$priceCents = round($planPrice*100);
// Create a plan
try {
$plan = \Stripe\Plan::create(array(
"product" => [
"name" => $planName
],
"amount" => $priceCents,
"currency" => $currency,
"interval" => $planInterval,
"interval_count" => 1
), array("stripe_account" => $stripe->id));
}catch(Exception $e) {
$api_error = $e->getMessage();
}
if(empty($api_error) && $plan){
// Creates a new subscription
try {
$subscription = \Stripe\Subscription::create(array(
"customer" => $customer->id,
"items" => ["plan" => $plan->id]), array("stripe_account" => $stripe->id));
}catch(Exception $e) {
$api_error = $e->getMessage();
}
echo $api_error;
