👋 happy to help

with coupons only that's not really possible

but what you can do is a combination between coupons and promotion codes

you first create a coupon and set its max_redemption to 50

then for each customer you create a separate promotion code and pass in the coupon, the customer and the max_redemptions 1

hm but if i have 1000 customers i would need to create 1000 promotions codes

i guess i could do that programatically, but then theres another problem

last time i tried using promo codes they don't really work with my app

since im using invoices, and as far as i understand you cant apply promo codes directly to invoices, only coupons

so how it works right now it, the customer inputs a promo code, and the backend looks for the coupon that it belongs to and applies that instead

which means it wouldn't increment that promo codes usage counts, only the coupon codes

[frozen briar]

is it for subscriptions?

[sonic basalt]

nope, just invoices

im using stripe API to create invoices, and the discounts object only accepts coupons, not promo codes

also, would having thousands of promo codes laying around (one for each customer) slow down API requests for fetching them do you think?

or would that not be a problem

[frozen briar]

sorry for keeping you waiting, but I was thinking of a workaround

[sonic basalt]

no problem

[frozen briar]

but unfortunately there isn't a straightforward solution

[sonic basalt]

i guess i could code it to manually increment the usage counts of the promo codes when they reach the backend

is that possible with the stripe API?

so even tho the promo code wasnt directly applied to a checkout, the usage count would still go up

[frozen briar]

I'm thinking of something simpler in a sense

basically you don't use promo codes

but instead you use only coupons and store the list of the customers that already used it

[sonic basalt]

oh

[frozen briar]

and check that list before applying the coupon

[sonic basalt]

so basically nothing would change in stripe

i can do the whole logic in my backend

yeah i think that would work

[frozen briar]

let me know if you need any more help

[sonic basalt]

i think that's it, i'll just save the coupons in the DB and save all the users that used them so they can't use them again

thanks for the help! 😄

sure thing
