I don't think you can add negative amount line items in a checkout session 🤔
Let me see if there's a workaround
full verge
thank you. so far, we have this whole process without importing all our product to stripe. we set up the cart on the fly per transaction.
We have implemented most of this :
just coupons and gift certificates now. which really, just need a place to apply and show the discounted amount, with a reference to the code used sent back to us
pallid wind
Gotcha. Unfortunately, there's no workaround to pass negative items to the checkout session.
The only way to provide discounts using Checkout Sessions is to use promo codes/coupons created on Stripe
full verge
is there a beta feature or something ? i was looking at this thing
not sure if it would apply
pallid wind
I don't think there's beta that works for this. One approach you could take is, when the customer applies a coupon/certificate on your site, you can call Stripe API to create a coupon/promo code on Stripe - https://docs.stripe.com/api/coupons/create | https://docs.stripe.com/api/promotion_codes/create
and then prefill/pre-apply it on checkout creation by passing them through discounts - https://docs.stripe.com/api/checkout/sessions/create#create_checkout_session-discounts
full verge
hmm. so like a pre-created coupon of fixed amount ?
pallid wind
correct
full verge
that could work. is there a way to ensure they can only be applied via the api ?
(eg, don't want a bunch of coupons created, then someone come along and use one)
pallid wind
You can create coupons that are single use - https://docs.stripe.com/api/coupons/create
or set a redeem_by date - https://docs.stripe.com/api/coupons/create#create_coupon-redeem_by

This is the hashing I am using for creating a line item (roughly, this shows an attempt for coupon code entry at 0$)
// create a line item for stripe checkout
formParams["line_items[#itemIndex#][price_data][currency]"] = "usd";
formParams["line_items[#itemIndex#][price_data][product_data][name]"] = "COUPON: #discountCode#";
formParams["line_items[#itemIndex#][price_data][unit_amount]"] = 0;
formParams["line_items[#itemIndex#][quantity]"] = 1;
Or create a promo code that can only be used by that specific customer - https://docs.stripe.com/api/promotion_codes/create
full verge
we have to do everything manually since coldfusion is not really supported.

You can create coupons that are single use - https://docs.stripe.com/api/coupons...
single use isn't the problem, it is if the user aborts the cart. my concern here, is user creates a cart, and aborts --- and ends up with dozens of coupons since the amounts will be different.
pallid wind
One option would be to delete the coupon if the cart is abandoned
full verge
that specific customer doesn't exist in your system yet
ok, if the coupon can not be applied by typing a code in stripe, then it should be fine.
pallid wind
👍

could you provide an example like this on how I would set a stripe coupon to our cart -- not on an item
// create a line item for stripe checkout
line_items[0][price_data][currency] = "usd";
line_items[0][price_data][product_data][name] = "COUPON: #discountCode#";
line_items[0][price_data][unit_amount] = 0;
line_items[0][quantity] = 1;
My test request was in stripe-node with following body:
options = ({
line_items: [
{
price_data: {
unit_amount: 10000,
currency: 'usd',
product_data: {
name: 'test'
},
},
quantity: 1
}
],
discounts: [
{
coupon: 'me9ftfRt'
}
],
success_url: url,
mode: 'payment'
})
so it's a separate thing
pallid wind
so discounts would look like
discounts[0][coupon]="xxxx"
^ ya. thank you
pallid wind
full verge
thank you so much 🙂
pallid wind
We have step by step guides in case you need it later - https://docs.stripe.com/payments/checkout/discounts?lang=curl
full verge
last question, a bit unrelated.
pallid wind
Sure
full verge
would you happen to know a rough eta on when google pay/apple pay/link/etc one-click checkouts will be enabled for the beta feature for custom shipping
pallid wind
Unfortunately, not. My team doesn't familiarize much beta features so we don't keep upto date on that. I would suggest you reach out to our support about that
