yes
and by acitve i mean everything like end date and usage
Do you want to said that active = true means is valid?
tender wigeon
actually the easiest way to check whether the promotion code will apply or not is to use the preview upcoming invoices https://docs.stripe.com/api/invoices/upcoming#upcoming_invoice-discounts-promotion_code
so basically if it's a new subscription you would pass in everything that you would normally pass to a subscription (customer and subscription_... fields)
blazing dome
Yes i know this
blazing dome
and for new subscritpion we can use during create subscription
tender wigeon
and if it's an existing subscription you would pass the subscription ID
blazing dome
Ok, great then
tender wigeon
in both cases if you want to make sure that the discount will apply is to retrieve the upcoming invoice before creating/updating the subscription
blazing dome
So if promo code will not be valid, then I will go and error yes? Or I will get full price?
tender wigeon
no you would have to check the https://docs.stripe.com/api/invoices/object#invoice_object-discounts on the returned invoice
and see if it was applied or not
tender wigeon
sure let me know if you need any more help
