Hi! Let me help you with this.
You can create a Coupon instead: https://stripe.com/docs/api/coupons

I don't want coupon. I want to give free 100 items in first month, so if user will buy 80 items, I want to add discount for 80 items and invoice will be 0.
But if user will buy 240, I want to create invoice with 240 items and discount for 100

You can create a coupon for a specific amount (cost of 100 items).
lunar canyon
but what if user will buy smaller amount? I don't want to add additional balance for him
is it possible to automaticly apply coupon?
gusty pier
Coupon doesn't add additional balance, while negative invoice amounts might.
You can also dynamically create a coupon, e.g. if quantity < 100 -> create a -100% coupon

i am asking about something different. I want to add automatic coupon for drafted invoice
(coupon already exists)
gusty pier
What do you mean by "automatic coupon" exactly? Not have the customer type in the code?
lunar canyon
yes, i want to add coupon by stripe
gusty pier
You can add a discount.coupon when creating an Invoice: https://stripe.com/docs/api/invoices/create#create_invoice-discounts-coupon
lunar canyon
but I have to do it manually when I receive event invocie created?
stripe cannot do it?
gusty pier
Is it for a Subscription?
gusty pier
Yes, you will need to update the Invoice manually when you receive the event, but it's a normal practice. That's exactly the reason why we don't finalize it right away.

ok, thanks
