What is the expected behaviour? Do you want the amount paid for the first month be partly refunded?
quick bramble
No. So I meant if the customer does not pay for the subscription after i create the subscription element without coupon and goes back to apply a coupon, when he pays he is charged the initial price without discount.
I would like to be able to apply the coupon to the current payment even if the subscription element was created already
this is my flow: select plan + add coupon -> register -> pay. I want the user to be able to return from payment -> select plan and apply coupon -> back to pay updated subscription

How do you apply the coupon?
quick bramble
this.stripe.subscriptions.update(id, {
promotion_code: promotionCode,
});
on the server side
using "stripe": "^8.193.0"
and I create the subscription like this:
const subscription = await this.stripe.subscriptions.create({
customer: customer.id,
items: [{
price: priceId,
}],
payment_behavior: 'default_incomplete',
payment_settings: { save_default_payment_method: 'on_subscription' } as any,
expand: ['latest_invoice.payment_intent'],
promotion_code: promotionCode,
metadata: {
internal_id: user.internal_id,
firebase_id: user.uid,
subscription_type: subscriptionType,
},
});

You can try to apply the invoice to the latest_invoice instead, I see it's a one-time discount, correct?
quick bramble
yes, it should be one-time
So i should update the invoice and not the subscription?
dire creek
Please try to see if it works in your case.
quick bramble
I will! thanks

Hi there 👋 jumping in as my teammate needs to step away. If the Invoice is finalized at that point, you may not be able to update it. The coupon will need to be applied before the invoice is finalized and gets locked.

Working on it! It will take me a bit because I need to add the update invoice method on the server and then use it on the frontend
quick bramble
I will go offline now, and get back to this on monday, I don't think it will work with updating the invoice
subscription is sub_1NTlx7Bn4amlqukbyE5sf5jH

Ah, that's what I was afraid of. I think if the Subscription has already been created, then there won't be a way to apply a Coupon that impacts the first payment. You would need to cancel the existing Subscription and create a new one with the Coupon.
