subscription-lifecycle

StoreKit 2 subscription lifecycle management handles post-purchase states by providing real-time monitoring, grace period tracking, billing retry detection, and entitlement mapping for access control. You initialize the generator with your StoreKit group ID to begin tracking.

Grace periods and billing retries are managed through real-time lifecycle monitoring that detects subscription state changes. The system maps these states to entitlements, allowing your app to maintain or restrict access control during payment failures.

Offer codes and win-back offers are supported through a comprehensive API surface that integrates with existing paywalls. The system provides guidance for combining these offers with server-side verification to ensure valid entitlements.

Upgrade, downgrade, and crossgrade paths are managed using entitlement mapping that links subscription tiers to access control levels. This allows your app to dynamically adjust feature availability when users change their subscription tier.

Server-side verification is supported as an optional integration path alongside the core lifecycle monitoring. The system provides guidance for combining real-time client monitoring with your server verification workflow to maintain entitlement accuracy.
