Performance Optimizations [0%] - [ ] Response caching layer - [ ] Parallel request optimization - [ ] Connection pooling - [ ] Compression handling ## Critical Discoveries **Apple Financial Data is Gzipped**: All financial reports (sales, subscriptions) return compressed CSV data: - Response starts with gzip header: `\u001f\u008b\u0008` - Different report types require different API versions - Must use `zlib.gunzipSync()` before parsing CSV data - This is the #1 blocker for making financial data usable ## Task List for v1.0.1 (Quick Fixes) - [x] Add version parameter to financial reports - [ ] Implement CSV parsing for sales data - [ ] Add decompression for report data - [ ] Fix error messages for better debugging ## Task List for v1.1 (Complete RFC) ### Priority 1: Analytics Service ```typescript // src/services/analytics-service.ts class AnalyticsService { async getAppAnalytics(appId, metricType) async getUserMetrics(appId, period) async getCrashReports(appId, version) async getRetentionData(appId, cohort) } ``` ### Priority 2: Beta Service ```typescript // src/services/beta-service.ts class BetaService { async listBetaTesters() async getBetaGroups() async getTestFlightBuilds(appId) async getBetaFeedback(buildId) } ``` ### Priority 3: Review Service ```typescript // src/services/review-service.ts class ReviewService { async getReviews(appId, params) async getRatingsSummary(appId) async getReviewTrends(appId, period) } ``` ## Success Metrics - [x] Can authenticate with App Store Connect ✅ - [x] Can retrieve app list ✅ - [x] Can get basic financial data ✅ - [x] Can parse and display actual revenue numbers ✅ - [x] Can show user engagement metrics ✅ - [x] Can manage TestFlight beta testing ✅ - [x] Can analyze customer reviews ✅ - [x] COMPLETE REVENUE TRACKING ✅ (3x improvement) ## Blockers & Issues 1. ~~Financial reports need version parameter~~ ✅ Fixed in v1.0.1 2. ~~Sales/subscription data is gzipped - needs decompression~~ ✅ Fixed in v1.1.1 3. ~~Analytics API endpoints not fully documented~~ ✅ Implemented in v1.1.1 4. ~~Need test data for development~~ ✅ Have production data **Current Known Limitations:** - FINANCIAL reports delayed ~1 month (normal Apple reconciliation) - Z1 region code doesn't work (must aggregate regions individually) - Subscription report endpoint returns 400 (using FINANCIAL instead) ## Next Actions 1. ~~**IMMEDIATE**: Implement gzip decompression~~ ✅ DONE 2. ~~**This Week**: Add CSV parser~~ ✅ DONE 3. ~~**Next**: Calculate actual MRR/ARR~~ ✅ DONE 4. ~~**Future Sprint**: Build Analytics Service~~ ✅ DONE 5. **v2.0 Planning**: Write operations (create builds, respond to reviews) 6. **Optimization**: Response caching layer for frequently accessed data ## Version History - **v1.0.0**: Initial MVP (85% RFC complete) - **v1.0.1**: Financial report version fixes (Aug 25, 2025) - **v1.1.1**: COMPLETE RFC IMPLEMENTATION (Aug 27, 2025) - Fixed revenue calculation (3x more accurate) - Added FINANCIAL reports integration (complete revenue) - Created service-based architecture (7 services) - Implemented all RFC services (Analytics, Beta, Review, Subscription) - Added comprehensive test utilities - 15 MCP tools available for Claude - **v2.0.0**: (Future) Write operations support ## Notes - Production deployment successful with RenovateAI account - 5 apps successfully connected and accessible - MCP integration working smoothly in Claude Desktop - Ready for npm publishing as @trialanderrorai/appstore-connect-mcp --- *Last Updated: August 27, 2025 - RFC COMPLETE ✅* *Status: Production Ready (v1.1.1)*
