We had users who paid on the web but the mobile app showed them as unsubscribed. That caused confusion, support tickets, and cancellations.
After syncing subscription state between the web checkout and our in‑app entitlement system the support volume dropped and we could run accurate win‑back campaigns. The tricky parts were id matching and handling delayed webhooks.
What are your rules for matching web payments to in‑app accounts and handling webhook delays?
We matched on user id where possible and fell back to email mapping.
Delays happen. We made the app poll entitlement state on open for a short window and accepted eventual consistency.
Integration was easier than expected with Web2Wave pushing a consistent subscription payload.
Syncing fixed a lot of false churn. We flagged users who paid but lacked entitlements and ran targeted reactivation offers. The results were measurable within weeks.
Having the sync live on the web funnel sped up fixes.
We use email plus a stored external id to match payments.
When webhooks lag, the client retries a fetch and shows a pending state. It cut support messages a lot.
email match then retry
show pending
We added a reconciliation job that runs nightly to fix missed mappings.
That cleaned up edge cases and reduced churn caused by entitlement mismatches.
We log webhook receipts and surface failures to support.
That helped identify a payment gateway misconfiguration quickly.
If you have RevenueCat or Adapty, sync the web purchase id there.
It makes app entitlement checks simpler.
