I mean user type a promotion code in coupon and validate this is valid or not
something like "SALE50OFF"
stoic cliff
hi! you can't validate it directly; either the customer types it into Checkout to use it, or you :
- call https://docs.stripe.com/api/promotion_codes/list#list_promotion_code-code to find the promo_xxxx object from the user-facing code
- pass it to
https://docs.stripe.com/api/subscription_items/create#create_subscription_item-discounts-promotion_code when creating a Subscription and see if it works
swift bone
I use invoice, step bellow:
Steps to use discounts with stripe
Split the payment form into two steps
Event details and coupon field
Payment form (card details, apple pay, google pay)
User enters or skips the coupon details on screen one and presses the submit/next button. Then we hit the API and do the following
Create a new invoice - https://docs.stripe.com/api/invoices/create
Create a new invoice item with the invoice id from step a and the coupon code if entered by the user in 1.a - https://docs.stripe.com/api/invoiceitems/create
Once the invoice item is created and attached to the invoice, finalise the invoice - https://docs.stripe.com/api/invoices/finalize
It will generate a payment intent attached to the invoice object
Return that payment intent id to the frontend
Use the payment intent id to render the payment form from step 2
User enters the card details and clicks pay now
Confirm the payment on the frontend using the stripe API (how it is working currently)

If user enter promotion code. I want call api to validte it

Create a new invoice item with the invoice id from step a and the coupon code if entered by the user in 1.a - https://docs.stripe.com/api/invoiceitems/create
This call will fail if the provided coupon/code is invalid
swift bone
Yep so I want a step before to validate the promotioncode is valid in specify subscription or not before create invoice
limber wraith
There is no endpoint really to validate the application of a coupon other than just trying to apply it
swift bone
no way to validate code is valid in products?
limber wraith
Not really, other than just trying to apply it to a subscription/invoice. You could use the retrieve endpoint I guess which will preview the invoice without actually creating it: https://docs.stripe.com/api/invoices/upcoming
swift bone
So I add promotion code -> create preview invoice -> check preview invoice is valid before create reality invoice with promotion code?
limber wraith
Yep should work
swift bone
sounds good, thank you, let me try it
Hey mate
relate this follow. Do you think should update any step? Please corrrect it and give better guidance if needder
swift bone
I use invoice, step bellow:
Steps to use discounts with stripe
Split the payment...
this flow
limber wraith
Seems fine, it's just a bit cumbersome because that's not really how the Invoices API is supposed to work (i.e. use the intent secret on the front-end)
swift bone
can you explain more detail?
after user click paynow in payment element, I wwill call strip.confirmpayment
limber wraith
What you have is fine. There's a lot of API calls sure, to create the invoice, add the items, etc. But that's just how the API works/is designed – nothing you can do to optimise that
swift bone
thanks mate, will try thiss flow
