Fix Stripe Webhook & Payment Gateway Issue in FastAPI Backend ($25 Fixed Price)

I am looking for an experienced developer to help resolve a specific issue with my existing Stripe integration in a FastAPI backend application. Scope of Work: * Review existing Stripe payment integration * Identify and fix the current payment processing issue * Debug and fix Stripe webhook event handling * Verify successful payment and webhook flow * Provide brief notes on what was fixed Requirements: * Experience with Stripe API * Experience with FastAPI/Python * Ability to troubleshoot existing code quickly Important: This is not a full Stripe integration project. The Stripe integration is already implemented, and I only need help fixing the current issue(s). The task is expected to be small and suitable for a $25 fixed-price budget. Please include: * Your experience with Stripe and FastAPI * Similar debugging/fix work you have completed * Estimated time to complete This version sets the expectation that you're hiring for a quick debugging task rather than a complete payment gateway implementation, which makes the $25 budget more reasonable.
