I attached relevant code

I believe we should provide a coupon id whether it's a downgrade/upgrade/purchase but

do we lookup the coupon that the input promotion code belongs to ?

is that the normal way to do this ?

[spare scroll]

Will the discount be input by the customer via a form, or is it applied programmatically in your integration?

[severe arch]

we use a setup session to save the card details & then they only select which card to pay with & for what but they'll have to input some kind of code from frontend in the new flow

so I was thinking that they need to create a coupon & promotion codes for that in the dashboard give them to whoever they want & on code we get the promotion code from input & validate it/get the coupon for that (I'm not sure about how this part is done) & then just provide the couponId to one of the methods mentioned above
