I'm sending my current subscription in subscriptions arg, and the new price to upgrade to in subscription_item
^ method just calls one that spreads that args object into a stripe call

If you pass in the Customer's coupon in the coupon property does it work as expected? https://stripe.com/docs/api/invoices/upcoming#upcoming_invoice-coupon
slim shell
I've tried that and it didn't seem to make a difference, I will try again now
i've added the coupon and the discount amount is 0
in lines.data the items have discountable: false
lone mesa
It sounds like the Coupon you're using doesn't apply to those items
slim shell
in the documentation, it says the exisitng coupons on the plan will be applied
I see them being applied if i get the upcoming invoice for the current plan
lone mesa
Can you paste the coupon ID here?
slim shell
but you're saying that if I get an invoice for an upgrade plan, i need to also pass the coupon?
'25-percent-discount'
lone mesa
Oh, sorry, I should have asked for the Discount ID.
slim shell
oh i might have an error looks like i'm passing the whole class, not the string
that is on the dashboard?
i'm searching the coupon section
di_1JwDtzJOFr5bboslPufjnwkj is the one from my response payload
hm doesn't exist on my stripe dashboard
lone mesa
Let me look...
Ah, that must be from the upcoming Invoice, it doesn't seem to exist. I was hoping to get the Discount ID from the existing Subscription where the coupon is working as expected.
slim shell
oh i see
i can get that
di_1JwCmaJOFr5bboslHUgGEruI
this is what discount I get on the current subscription upcoming invoice (no upgrade, no coupon param)
just the exisitng coupon

Looking back at the original Subscription creation request it looks like the coupon is being passed in as a one-off and is not attached to the Customer beyond that: https://dashboard.stripe.com/test/logs/req_aoOCatjGdfxGPU
That explains why no discount is shown if you don't specify coupon when getting the upcoming Invoice.
slim shell
at the time of first purchase?
lone mesa
Yeah, when the Subscription was created.
slim shell
how do I attach the coupon to the customer?
I guess its in update customer API https://stripe.com/docs/api/customers/update#update_customer-coupon
lone mesa
Yep.
slim shell
thanks alot.
was stuck on this for a couple days, will try this
I send coupon info when creating customer, and the discount didn't apply di_1JwERGJOFr5bbosllh28LXxX

or is it something I have to calculate from these amounts?

👋 I'm hopping in for @lone mesa - give me a minute to catch up!
slim shell
it actually seems like the response is correct, I may be reading the response incorrectly.
coarse meadow
Just to make sure I understand - your core issue is that you have a customer discount set, but it doesn't seem to be applying to the upcoming invoice like you expect it to
slim shell
yes, but I think the issue is solved, becuase I do see the correct price in the response object, i'm just a little confused how to read it. my current code is reading the plan.amount which is not the correct price
does this represent the new recurring charge to the customer after upgrade?
oh no, that's the old plan price
it should be this. I'm using plan.amount but I should be using .amount
coarse meadow
If you're looking for the amount due for a specific line item then yes, it would be at amount not plan.amount
slim shell
ok i have no issue, that is the correct amount
