In-app purchases and subscriptions with RevenueCat. Use for paywalls, odd sandbox behavior, premium not arriving after purchase, webhook verification, restore and transfer flows.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Subscriptions without 2 AM incidents

## The architecture rule everything else hangs on

Entitlement truth lives on your server, not in the client. The purchase SDK tells the client "probably premium" fast; the webhook pipeline tells your database "actually premium" reliably. The client renders from server state and treats its local SDK state as an optimistic hint.

Every horror story in this domain is a variation of trusting the client: premium flags in AsyncStorage, entitlement checks that only run at purchase time, or webhook handlers that were never verified against replay.

## RevenueCat wiring that holds up

- Identify the user to the SDK with your own auth user id after sign-in. Anonymous ids merging into identified ids is where "user bought on the wrong account" tickets are born.
- Configure once at startup with the platform key; render from `customerInfo` listeners rather than one-shot fetches, so a purchase completing in the background updates the UI without a restart.

How to install

The exact contents, by fingerprint

mdr add anilburcu/claude-code-react-native/in-app-purchases@sha256:6ccfc4c2faf2c490

The line at the top of this page pins the label git:20260911.98ac3cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
