You can list all Promotion Codes that have a specific Code - see https://stripe.com/docs/api/promotion_codes/list#list_promotion_code-code

Thank you. And 1 more question. We are use the checkout session payments with enabled promotion codes. Can I retrieve the promotion code in this session by any callback?
So I need to know did user use the promotion code or not, and if he used, what the code?

@ornate jewel let me look
The info about the discount(s) claimed if any would be in this: https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-total_details-breakdown-discounts you need to retrieve them via the API after you get the event

But now i receive only the discount amount instead the discount id. How I can set up to retrieve the discount id?
This is checkout.session.completed callback

that's expected, the information inside breakdown is not included by default, you have to explicitly expand it. You can read more about expand here: https://stripe.com/docs/expand
So when you get the event you need to retrieve the Session and pass expand: ['total_details.breakdown']
ornate jewel
Ohh, ok, I will try. Thank you
ornate jewel
Can I expand multiple parameters like expand: [
'total_details.breakdown',
'total_details.breakdown.discounts.promotion_code'
] ??
noble cloud
yeah but that's expected
expansion works based off of the API layer
total_details -> breakdown -> discounts -> discount -> promotion_code
you can't just pass promotion_code after discounts, there's a layer in between
sadly, the maximum is 4 deep so you won't be able to reach promotion code
ornate jewel
Ohh, yep, I see 🙂 So thank you 🙂
noble cloud
sure! Expand is super easy once you grasp it fully but it takes a while to resonate 😦
