Payments on App Store, Google Play, Stripe with one RevenueCat Setup

June 7, 2026 While digging through old notes, I found a guide I wrote around two years ago about setting up revenue subscriptions and testing them locally. It covers mobile payments on the App Store and Google Play Store, plus web payments with Stripe, all wired through RevenueCat. The RevenueCat docs are solid, so the guide doesn't repeat them. It's more of an ordered checklist: what to configure on each platform, which keys go into your settings.json, and how to test locally with sandbox accounts, ngrok for webhooks, and the Stripe CLI. I added it to my-docs as Revenue Cat Setup. If you're setting up subscriptions across iOS, Android, and web, it might save you some time.
