# Meta Instant Games SDK V8.5 Sunset & Migration Guide
The sunset of Meta Instant Games SDK v8.5 represents a critical inflection point for WebGL and HTML5 instant game developers. Meta's updated platform requirements mandate zero legacy synchronous calls, strict PII privacy controls, and modern asynchronous initialization via SDK v9.x+.
Executive Summary Legacy WebGL builds relying on `FBInstant.initializeAsync()` v8.5 patterns face automatic platform suspension. This guide details forensic scanning, step-by-step code refactoring, and WGL-CERT certification parameters.
Critical Breaking Changes 1. **Deprecated Payment APIs**: `FBInstant.payments.getCatalogAsync()` signature changes. 2. **Context Switching**: Synchronous payload passing removed in favor of encrypted session tokens. 3. **Memory Management**: WebAssembly heap allocation limits enforced at 512MB max per instance.
// LEGACY (DEPRECATED): v8.5 initialization
FBInstant.initializeAsync().then(function() {
FBInstant.startGameAsync();
});// CERTIFIED (v9.x+ Standard): WGL-CERT Approved async function initMetaGame() { await FBInstant.initializeAsync(); FBInstant.setLoadingProgress(100); await FBInstant.startGameAsync(); } ```
