For discussing the development and integration of subscription-enabled shops using Shopify's Subscription APIs.
For example, free to use in the early version of the app.
Then charging in the later version.
Could this be allowed officially, or cannot be changed?
Thank you for your kind reply.
Just to clarify, are you referring to something like a free trial? If so, yes this should be possible using the Billing API - see these docs: https://shopify.dev/apps/billing/purchase-adjustments/free-trials and https://shopify.dev/apps/billing.
To learn more visit the Shopify Help Center or the Community Blog.
Thanks for your kind reply.
Actually, I want to know if a free app can be changed to a charged app in the following release version. 🙂
