Mobile SDKs

Voidhash ships three client SDKs: one for React Native, one for Swift, and one for Kotlin. Each SDK adds entitlements, feature flags, analytics, and observer-mode transaction reporting to your app. In observer mode, the SDK watches the store transactions your existing billing integration makes and submits them to Voidhash for revenue analytics. It never takes ownership of billing away from your code. All three SDKs talk to the same project schema.

All three expose reportTransaction(...) for store values captured from the host billing SDK's successful purchase or restore result. syncPurchases() provides fallback scans when the host exposes no transaction values. Automatic observers and scans can miss purchases, especially consumables already finished or consumed by the host. See each SDK's purchase guide for integration examples and delivery limits. A valid report is persisted before it returns and delivered in the background, so a network or service outage delays reporting without interrupting the purchase flow.

Each SDK integrates with the store for its platform. The React Native SDK runs on iOS and Android and reaches StoreKit 2 and Google Play Billing through native modules. The Swift SDK runs on iOS and uses StoreKit 2. The Kotlin SDK runs on Android and uses Google Play Billing.
