another thought I add was to update the coupon on the fly, prior to creating the subscription, and restrict it to the specific price, but alas the update coupon API doesn't allow it

Can you detail more explicitly each of the steps of your desired flow? I feel like this could be solved by creating separate Subscription Items, but I'm not entirely sure without more context.

It's a hybrid situation.
Customers are allowed to purchase a one time product and a subscription at the same time.
And sometimes there is a promo code, but the way the system was designed, the equivalent Stripe Coupon cannot be restricted.
When there is a promo code for a subscription, I need to apply it only to the subscription.
Currently because when I create the subscription I pass the param "coupon" and the invoice is immediately finalized, the promo is applied to the invoice, including the one time purchase, which is not the behavior we want
That's why I wanted to not use the coupon param anymore and update the invoice line manually and then finalize the invoice manually
so to be clear, if they are only buying a subscription it's a non issue because the coupon will apply only to it
but if they have a pending "one time purchase" then it's a problem because it gets discounted as well
sharp robin
Ahhh, okay I see. I think you'd have to do one of two things, either:
(a) create the one-off charge separate from the Subscription, or
(b) track the discount on your end then and use a Subscription Schedule to model the discount (docs overview here: https://stripe.com/docs/billing/subscriptions/subscription-schedules)

yep that's what I was thinking too
thanks for confirming
is there any gotcha?
our subscription are usually pretty simple with: customer, application_fee_percent, items.price and trial_end params
looks like that would all be in one phase?
sharp robin
yep, exactly. The next Phase could then be used to update the amount and trial or whatever other mechanisms you have in place to determine the behavior of the Subscription
