I'm integrating Shopify GraphQL Billing API for my app. I have plans and add-ons, users can choose one of the plans and add a certain amount of add-ons. Downgrading your plan will change the recurring subscription accordingly with ReplacementBehaviour being
APPLY_ON_NEXT_BILLING_CYCLE
whereas if you upgrade to a higher plan it will be
APPLY_IMMEDIATELY
and charge you the full price. Everything is okay till now. But the issue is If the user has an add-on added I want it only to charge the user the add-on price now and from the next cycle charge plan+addon. I couldn't find a way to get around this.
For instance, let's say I have three plans:
s - 10$
m - 20$
p - 30$
and one addon priced at 5$.
If the user is on the m plan, and they add two addons I want them to be charged immediately:
2x5$ = 10$
and starting from the next cycle:
20 + 2x5 = 30$
Is there a way to achieve this kind of behaviour? I searched the docs and forums but haven't found anything relevant. Am I missing something? Any help is much appreciated!
Regards,
Asker Ali!
