How to add a * Stripe * subscription coupon with Laravel Cashier after a subscription has already been created

Question

According to the Stripe documentation, it looks like you can really apply coupons to the customer as a whole, but you can also apply coupons to their subscriptions. I am trying to apply a coupon to a customer’s subscription after the subscription has already been created. I am using Laravel Cashier 4.2.

Here is what I tried:

 $company = Auth::user()->company;
 $customer = $company->subscription()->getStripeCustomer(); // returns a StripeGateway object
 $customer->subscription->applyCoupon($input['coupon_code']);

Here is the error message:

"Call to undefined method Stripe_Subscription::updateSubscription()"

I can use the method applyCoupon()for the client as a whole, but not the actual subscription ... Ideas are appreciated.

The Stripe documentation only shows how to remove a discount from a subscription: Discount object . The only other information that I could find in their documentation is:

Coupons and discounts

, Subscription Laravel\Cashier\Subscription.

withCoupon():

public function withCoupon($coupon)
{
    $this->coupon = $coupon;

    return $this;
}

swap() . - $subscription->save();.

...
// Applying the discount coupon if such exists
if ($this->coupon) {
     $subscription->coupon = $this->coupon;
}
...
$subscription->save();

, , , - Billable subscriptions(), Subscription.

After that, you can apply your own trait Billableto the paid model and apply coupons when exchanging plans.

$user
    ->subscription($product)
    ->withCoupon($coupon)
    ->swap($plan);
