Quickstart
Pick your platform and show your first paywall.
Voidhash ships native SDKs for every major mobile stack. Each quickstart takes an existing app from installation to a working paywall and entitlement check.
React Native
Expo development builds and bare React Native apps on iOS and Android.
Swift
Native iOS apps with StoreKit 2. Requires iOS 15+.
Kotlin
Native Android apps with Google Play Billing. Requires minSdk 23+.
What you need before you start
- a Voidhash project with its publishable key (
vh_pk_...) — store credentials and secret keys never ship inside the app; - a subscription or one-time product in App Store Connect or Google Play Console; and
- a paywall published in Studio, assigned to a location such as
onboarding.
The React Native quickstart uses development purchase mode so you can test without store setup first. Swift and Kotlin test against App Store Sandbox or Google Play testing tracks from the start — see Store setup and Connect Google Play.
