Hello
The AI is unfortunately incorrect
PaymentIntents API does not support promotion codes/coupons
latent galleon
hi Hanzo, how can we use the promo code then in this scenario?
manic fractal
With PaymentIntents, you'd need to add your own fields for coupons, calculate the discount, update the PaymentIntent amount and then use something like fetchUpdates() to update your Elements object with the latest details.
https://docs.stripe.com/js/elements_object/fetch_updates
You can use this API endpoint to update the PaymentIntent amount - https://docs.stripe.com/api/payment_intents/update#update_payment_intent-amount
latent galleon
oh so we need to do the calculation ourself?
manic fractal
That's correct. The PaymentIntents API is bare metal.
If you use Stripe Checkout API then we calculate discounts for coupons/promo codes but with PaymentIntents, the merchants/developers have the full control
latent galleon
then how we get reports on how many times a code had been used or things like that
I mean if we are not passing the promo code to Strip at the time of check out how we get the analytics at it
manic fractal
You'd need to track it manually (in your own database) when you do the calculation
latent galleon
oh so we have to implement the whole logic on our end?
manic fractal
With PaymentIntents API, unfortunately - yes
latent galleon
got it...also could you plz elaborate more on why we should do fetch_update on element object? as its not holding any payment info?
manic fractal
It's because when you update the PaymentIntent's amount server-side, you'd also need to update it client-side so that the customer sees the right amount for let's say Apple Pay or Google Pay modal
latent galleon
one last question for u Hanzo, can we use ur coupon and promo code APIs along with payment Intent endpoint
to like update the info on stripe end abt the usages of promocodes and things like that
or validating the code as well
manic fractal
It is not something the API supports today.
You could validate the coupon/promotion code by retrieving it but since you'll need to track the redemption in your own Database anyway, it'd be better to just validate on your end as well (without using Stripe's APIs)
latent galleon
got it thanks
could u also verify if each coupon is only associated to only "ONE" promo code?
is each promo code is associated to one coupon I better ask
manic fractal
Coupons can have multiple promotion codes but a promocode can only be associated with one coupon
