4. Your AI fair split — pay your share
Each card explains the share in plain language and includes a friendly draft payment request. Pay below, one friend at a time.
How PayPal works here
- Sandbox demo mode (default): The button says “Sandbox demo — no real money.” Clicking it simulates a successful sandbox payment, marks that friend paid, and updates the dashboard. No money moves.
- Real sandbox mode: Paste a PayPal Sandbox Client ID into
config.jsand reload. The app then loads the official PayPal JavaScript SDK and shows real PayPal Buttons for each share, created in the browser for sandbox testing. - Production note: A live production integration would need a server to create and capture orders securely. This hackathon demo intentionally stays in sandbox, with no server, no secrets, and no real money.
