Stripe Subscription Integration Expert

My SaaS platform is already live, written in Python with FastAPI, and I have a Stripe product set up at $2,499 per month. All that’s missing is the final wiring: the checkout needs to pull that Product ID, run the full subscription flow, and trigger the right webhooks...
