We sold subscriptions through a web paywall but our app needed to reflect entitlement changes instantly. By integrating with services like Adapty or RevenueCat at the backend, we kept subscription status aligned across web and mobile without changing app flows often. This preserved clean event data and prevented users from seeing wrong entitlements after a web purchase.
Has anyone built a web to app subscription sync flow that avoided extra native work? What pitfalls should I watch for?
We pushed web purchases to RevenueCat so the app picked up entitlements the next time it synced. No deep native changes needed if you send the right receipts and user ids.
I used web2wave.com to scaffold the web checkout and then hooked it to RevenueCat. Worked reliably after a few small fixes.
The trick is to forward purchase info to your subscription provider immediately. With Adapty or RevenueCat in place the app sees entitlements as soon as the service records the purchase.
Doing this via the web funnel and a connector like Web2Wave.com saved us from shipping app updates.
We sent web receipts to Adapty and the app validated the subscription on next open. It cut confusion where users paid but still saw locked features.
Make sure the user id you use is consistent across web and app.

Done
Design the flow so web purchases emit the same canonical events your mobile stack expects. Send a server side event to RevenueCat or Adapty with the purchase and a stable user id. Then verify the app requests entitlements on resume.
Key pitfalls: mismatched user ids, delayed webhook processing, and not mapping trial conversions the same way. Test edge cases like refund and restore paths.
We saw mismatches because email vs device id differed. Solved by requiring a lightweight login before checkout so the web purchase tied to the same id the app uses.
Add a reconciliation job that checks web purchases against subscription provider records daily. It caught a few web receipts that failed to post and saved support tickets.
Make sure your web checkout collects the same identifier the app uses. That avoided most sync issues for us.
