- Identity is the hard part, not the entitlement check itself.
- Map Stripe products to app entitlements so iOS code stays store-agnostic.
- Keep test and live environments fully separated while you wire the flow.
Definitions used in this guide
A verified view of subscription state, renewals, refunds, and active access across all payment rails.
A policy that lets one customer unlock the same entitlement across iOS, Android, and web.
The process of checking incoming events against the source system so missed webhooks do not leave access or revenue wrong.
What should be true before you start?
Before you connect Stripe to iOS access, decide how one person becomes one customer across web and mobile. If your identity model is weak, the same subscriber will look like two separate users and access restoration will feel random.
- Define a stable user ID that both your web app and iOS app can resolve.
- Choose the entitlement the web subscription should unlock, such as
pro. - Keep Stripe test mode and iOS sandbox flows separate from live data.
How should you implement this step by step?
The implementation path is straightforward once identity is stable. Stripe completes the purchase, your backend verifies and records the subscription event, Crossdeck projects the entitlement to the customer record, and the iOS app checks isEntitled("pro") on launch or restore.
- Create or map the Stripe product, such as
stripe_monthly_pro, to the entitlementpro. - Attach the Stripe checkout or subscription update to the same customer identity the iOS app will later identify with.
- Verify the Stripe event on the backend and update the entitlement state server-side.
- Have the iOS app identify the same user and resolve the entitlement instead of trying to interpret Stripe billing details client-side.
| Step | Web side | iOS side |
|---|---|---|
| Identity | Stripe checkout tied to a stable customer ID | iOS app identifies the same customer ID |
| Access model | Product stripe_monthly_pro maps to pro | App checks pro, not Stripe status |
| Environment | Test mode and live mode are split | Sandbox and production stay split too |
await Crossdeck.identify(userId: "user_847")
let hasAccess = await Crossdeck.isEntitled("pro")
if hasAccess {
unlockPremium()
}Where do teams make mistakes?
Most broken cross-platform access flows come from treating checkout completion as enough without solving identity or environment discipline.
- Creating a new anonymous identity on iOS instead of resolving the signed-in web customer.
- Checking Stripe subscription details directly in the client app.
- Letting test-mode subscriptions contaminate live entitlement state.
How does Crossdeck operationalize the workflow?
Crossdeck turns the problem into one entitlement question instead of a Stripe-on-web versus Apple-on-mobile debate. Once the customer record is unified, whichever payment rail granted pro can unlock the same feature set everywhere.
That creates a better experience for founders and users alike: one paid relationship, one access state, and fewer restore-access support tickets.
Frequently asked questions
Should iOS know whether the payment came from Stripe or Apple?
Usually no. The iOS app should care about entitlement state. The rail source matters for reporting and support, not for core access checks.
What if the user buys on web before creating an iOS account?
You still need a strategy to merge or resolve the identity later. Cross-platform access always becomes an identity problem before it becomes an entitlement problem.
Why keep test and live fully separate?
Because environment leaks create fake revenue, misleading support cases, and accidental premium access decisions that are hard to debug later.
Does Crossdeck work across iOS, Android, and web?
Yes. Crossdeck is designed around one customer timeline across Apple, Google Play, Stripe, and web or mobile product events, so the same entitlement and revenue model can travel across surfaces.

Use the Stripe docs path first, then confirm that the iOS app resolves the same entitlement after web checkout completes.
