Backend Payment Processing Fix

My digital product is live but the checkout flow stalls because payment processing is still missing. I want the backend updated so customers can pay with multiple forms—credit cards, PayPal and, if feasible, a crypto option. The immediate task is clean integration with a reliable payment gateway; I’m open to Stripe, PayPal, Square or another solution you can justify for our tech stack. What you’ll tackle: • Wire the chosen gateway into the existing backend, set up the necessary endpoints and webhooks, and make sure tokens and keys are stored securely. • Implement exhaustive sandbox testing, then push to production once we’ve confirmed successful transactions. • Add lightweight reporting so I can see a summary of completed, failed and pending payments from the admin panel or an API endpoint. • Deliver well-commented code, an `.[login to view URL]` for secrets, and short deployment notes so future maintenance is straightforward. Security and reliability are non-negotiable; please follow PCI guidelines, encrypt secrets, and log errors without exposing sensitive details. The sooner we can accept real payments the better, so propose a realistic timeline and any stack requirements you have and let’s get this wrapped up.
