My admin panel already handles user management and basic transactions, but it still lacks native Bharat Bill Payment System support. I need Finpay’s BBPS APIs wired in so that end-users can both view their pending bills and pay them directly from the dashboard. Scope of work • Consume Finpay’s bill presentment API to pull live bills on demand and display them neatly inside the panel. • Build the payment flow that posts the transaction to Finpay, handles any OTP or checksum steps they require, then returns a clear success or failure status. • Capture and store bill history with searchable filters (date range, biller, status). • Issue PDF / downloadable receipts and show on-screen confirmations for every successful payment. Key points – Only Finpay is in scope; other BBPS aggregators such as Paytm, PhonePe or MobiKwik are not required. – The focus is bill presentment and payment; no automated reminders are needed right now. – Security (token handling, checksum validation, HTTPS) must mirror Finpay’s documentation. – Clean, well-commented code that I can drop straight into the existing Laravel back end (or plain PHP if you prefer). Acceptance criteria 1. A user enters a consumer number, presses “Fetch Bill,” and the panel returns accurate bill data from Finpay. 2. Clicking “Pay” completes the transaction, updates status in Finpay, and logs the response in my database. 3. A receipt (with Finpay reference number, amount, date, and biller) is auto-generated and downloadable. 4. All interactions are testable in Finpay’s sandbox before moving to production credentials.
