๐Ÿงฉ Recent Fix: Payment failure/cancel redirect UX (Aug 2025)

Issue observed

  • Clicking โ€œFailureโ€ in Razorpay sometimes showed โ€œCannot GET /api/payment/callbackโ€, or redirected borrowers to /lender where a role-guard popped โ€œAccess denied. You are not a lender.โ€

What we changed (server)

  • Added GET /api/payment/callback to handle Razorpay GET-style redirects on failure, mirroring the POST handler.
  • Both POST and GET /api/payment/callback now render a small branded interstitial page and then auto-redirect back to the SPA with clear query params.
  • POST /api/payment/create-order now returns checkoutUrl that points to the server-hosted checkout page and includes a fallback role parameter:
    • Repayment โ†’ ?fallback=borrower
    • Funding โ†’ ?fallback=lender
  • Server-hosted checkout pages forward fallback into Razorpayโ€™s callback_url so, even if orderId is missing, the callback knows which dashboard to return to.
  • Callback picks destination by reading the orderโ€™s notes.isRepayment; if unavailable, it falls back to the ?fallback value.

What we changed (client)

  • BorrowerDashboard and LenderDashboard:
    • Show a friendly banner after redirect based on ?payment=success|failed&reason=...
    • Persist last_order_id and, if the user closes the gateway without redirect, poll GET /api/payment/status/:orderId once to resolve status.
    • Clean the query string after showing the banner.

Expected behavior

  • On cancel/failure: you briefly see an interstitial page, then land on /borrower or /lender with a banner and URL like:
    • /borrower?payment=failed&order=order_...&code=...&reason=...
    • /lender?payment=failed&order=order_...&code=...&reason=...
  • On success: you land on the correct dashboard with ?payment=success and a success banner.

Endpoints involved

  • POST /api/payment/create-order โ†’ returns { id, amount, โ€ฆ, checkoutUrl }
  • GET /api/payment/checkout/:orderId[?fallback=role]
  • POST /api/payment/callback (success/failure)
  • GET /api/payment/callback (failure or when gateway uses GET)
  • GET /api/payment/status/:orderId (dashboard polling fallback)

Quick test

  1. Start backend and frontend.
  2. As a borrower, initiate a repayment and click Failure in Razorpay โ†’ you should be redirected to /borrower with a โ€œPayment failedโ€ banner.
  3. As a lender, initiate funding and click Failure โ†’ redirected to /lender with a โ€œPayment failedโ€ banner.
  4. Close the gateway without redirect โ†’ on next load, dashboard polls status for last_order_id and shows the proper banner.

Troubleshooting

  • If you see โ€œCannot GET /api/payment/callbackโ€, ensure the API has the new GET route and has been restarted.
  • If redirected to the wrong dashboard, check that checkoutUrl contains ?fallback=borrower or ?fallback=lender and that callback_url also includes the same fallback.
  • See PAYMENT_DEBUG_GUIDE.md for deeper diagnostics.
  • Communicate with borrowers
  • Submit disputes for problems
