This project is a reference implementation for integrating Stripe payment processing into an application. It provides a boilerplate for managing the end-to-end checkout lifecycle, specifically focusing on binding local user accounts to third-party payment identities.
The implementation utilizes a payment checkout orchestrator to coordinate the creation of customer identities and checkout sessions. It includes a dedicated webhook processor and subscription state synchronizer to mirror external payment data into a local database, ensuring application state remains consistent with asynchronous provider events.
The system covers subscription lifecycle management and identity mapping, including mechanisms to enforce subscription limits and prevent duplicate active plans per customer. It handles data synchronization through shared logic used across both webhook listeners and success pages.
