The Developers section is for engineers wiring WinWinKit into an app. It covers the SDKs, the REST API, authentication, and limits.

What you can build

With WinWinKit you can:

• Register users so the platform knows about everyone in your app.
• Claim codes (referral, affiliate, promo) on behalf of a user.
• Read reward state to show granted credits, entitlements, or offer codes in your UI.
• Spend credits when a user redeems an in-app credit reward.
• Track conversions automatically when a user becomes premium (via RevenueCat) or manually via the API.

Two ways to integrate

• SDKs — typed, idiomatic clients for Swift, Kotlin, Dart, and TypeScript. Use these when an SDK is available for your platform; they wrap the API and ship convenient observable/state types.
• REST API — call any endpoint from any runtime. Use this when no SDK fits, or when you're integrating from a server.

Both paths talk to the same backend and require an API key.
