Using embed app for show subscription page and then use external app

Topic summary

Main goal: after app install, present multiple subscription plan pages so the merchant can choose a plan.

Flow: show plans, redirect the merchant to a subscription acceptance page, then proceed once the subscription is approved.

Post-approval requirement: disable the embedded app UI and allow the merchant to use only an external app that interacts via GraphQL.

Key question: whether Shopify supports using embedded app functionality for initial subscription onboarding and then switching to external-only app logic after approval.

Terms: embedded app = app UI shown inside Shopify Admin; external app = standalone web app; GraphQL = Shopify Admin API for data operations.

Status: no answers or decisions yet; the feasibility of this flow in Shopify remains open.

I new in Shopify development,

I start new project where the main requirement is multiple subscription page after app install.

After install app, user can see subscription plans and choose one of them, after that i will redirect him to subscription accept page and then after subscription approved user can’t integrate embed app, hi can use only external app with GraphQL.

Can i do that in Shopify, can i use embed app functionality and then switch to external app logic?
