How vishnuweb-a/firnvia works

Firvanra is a hosted-payment checkout demonstration: shoppers browse services and ebooks, build a cart, create an order, choose a gateway, complete hosted payment, and view order status. The backend derives and signs payment data, verifies provider callbacks before changing order state, and keeps orders in process memory rather than durable storage. The README documents AirPay, AirPay 2, SabPaisa, PayU, and HDFC; sampled code shows the main routing and several provider integrations. Some frontend page and gateway internals were not excerpted, so their connections are shown only where the README or source index supports them.

Main entry points: api.js API Client · server.js Express API · payment.js Payment API · orders.js Orders API
