Store metadata in a subscription with Stripe - stripe-payments

Question

I'm trying to figure out how to store metadata directly into a Stripe CC payments subscription. I'm using the PHP SDK and have:
$test = $stripe->checkout->sessions->create([
'customer_email' => $_GET["who"],
'success_url' => $success_url,
'payment_method_types' => ['card'],
'cancel_url' => "https://www.example.com",
'line_items' => [
[
'price' => $price_plan_id,
'quantity' => 1,
],
],
'payment_intent_data' => [
'metadata' => [
'who' => $_GET["who"],
'total' => $_GET["total"],
'period' => $_GET["period"],
'description' => $_GET["description"],
'district' => $_GET["district"],
'what' => $_GET["what"],
'ip' => $_SERVER["REMOTE_ADDR"]
]
],
'mode' => $mode 'subscription',
]);
This gives me an error:
You can not pass payment_intent_data in subscription mode.
I've tried just doing:
$test = $stripe->checkout->sessions->create([
'customer_email' => $_GET["who"],
'success_url' => $success_url,
'payment_method_types' => ['card'],
'cancel_url' => "https://www.example.com",
'line_items' => [
[
'price' => $price_plan_id,
'quantity' => 1,
],
],
'metadata' => [
'who' => $_GET["who"],
'total' => $_GET["total"],
'period' => $_GET["period"],
'description' => $_GET["description"],
'district' => $_GET["district"],
'what' => $_GET["what"],
'ip' => $_SERVER["REMOTE_ADDR"]
],
'mode' => $mode 'subscription',
]);
And while it kind of works, its not assigned to the subscription (when you view it metadata is empty)
How do I go passing this along? I want to keep this data stored in the subscription element (not just the payment)
Thanks

You want to pass the metadata on to the resulting Subscription object by setting it in subscription_data.metadata: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-subscription_data-metadata
