My primary goal—described in the brief as “typing”—is really about accurate, friction-free data capture throughout the checkout flow. To achieve that I want a new payment gateway built into my existing site that supports two methods I have confirmed: Bank Transfer and PhonePe UPI. The integration must create, confirm and reconcile payments, update order status automatically, and surface clear success or error messages to the user. Please wire it to whatever stack the site already uses (I’ll share repo access as soon as we start) and respect common security practices: HTTPS end-points, token-based authentication with the providers, and no plaintext storage of sensitive data. Deliverables • Fully working gateway module connected to both Bank Transfer and PhonePe APIs • Callback/webhook handling that updates my database in real-time • Configuration notes plus any environment variables needed for production • Test script or Postman collection proving transactions succeed in sandbox and live modes • Brief hand-off document so future devs can maintain the code Acceptance criteria: both payment methods run end-to-end without manual intervention, order records match provider receipts, and error handling never reveals private keys or personal data.
