I need someone to connect my Stripe account to my web app hosted at base44.com. The goal is straightforward: - Set up the Stripe account - Set up secure one-time payment processing. - Enable recurring subscription billing. Your task covers the basic configuration of Stripe Dashboard settings, API keys, and the minimal code required to trigger charges and handle success / failure callbacks. If a lightweight webhook is needed to confirm payment events, include that as well. The app is not yet live; I simply want payments flowing smoothly—no advanced analytics or custom portals at this stage. Please be comfortable working with the Stripe API and able to show a quick test proving that both payment types complete end-to-end.
