Hi 👋 can you summarize your concern/question here for me?
lone belfry
yes of course !
(thx for opening it again)
As a good to know, we currently use the notion of subscription in Stripe to bill our customers.
For a few days now, we've been testing a new specific case.
It involves a subscription update (formula upsale) with a coupon. We currently use pending_if_incomplete for subscription updates.
Sometimes, 3DS authentication is required for the change. We manage this by launching Stripe.js, which performs this verification.
In this case, we get the following error: When payment_behavior is set to pending_if_incomplete, you can only pass supported params. coupon is not supported.
Knowing that if no 3DS authentication is requested, everything works fine.
Do you have a solution for us in this case? We've tried using the other payment_behavior values, but there's nothing satisfactory for us. For example, if the 3DS fails, the subscription is cancelled, which we don't want.

When do you encounter that error? Can you share the ID of a request where you're seeing that?

Thank you, taking a look.
Ah I see, yeah, that looks expected as coupon is not a supported parameter to provide with a pending updates flow:
https://docs.stripe.com/billing/subscriptions/pending-updates-reference#supported-attributes
It looks like with current system behavior your choice is to either use a coupon or use pending updates.

I can file feedback with our teams that this is a limitation that you'd like to see removed in the future.

That's what I've been trying to think through. What kind of coupon were you trying to apply?
