Standard Checkout to Marketplace Route — we engineer every Razorpay product with bulletproof webhook handling, idempotency, and GST-compliant invoicing baked in.
Every Razorpay product — engineered for production, not just demos.
Embed Razorpay's hosted checkout or build a fully custom payment UI using Razorpay.js. We handle order creation, payment capture, failure retries, and real-time status sync.
Full implementation of Razorpay Subscriptions — plan creation, addon charges, pause/resume cycles, proration, and dunning logic for failed payments. Supports UPI AutoPay NACH mandates.
Split payments between multiple vendors, freelancers, or sub-merchants in real time. We build the linked account onboarding, transfer scheduling, hold logic, and settlement reporting dashboard.
Generate dynamic UPI payment links, QR codes, and Smart Collect virtual accounts for B2B invoice collection. Includes IMPS/NEFT reconciliation and automatic payment matching.
Production-grade webhook handler with HMAC-SHA256 signature verification, idempotency keys, retry queuing (Celery / BullMQ), and nightly reconciliation reports against your accounting system.
Automated GST invoice generation on payment success — GSTIN, HSN/SAC codes, tax breakdowns, PDF generation, and email delivery. Full refund API integration with dispute escalation workflows.
We write clean, production-safe code — not copy-pasted from docs.
Webhook verification with idempotency guard. Every payment event is acknowledged exactly once, even under retry storms.
// Webhook handler — production-safe const crypto = require('crypto'); app.post('/webhook/razorpay', (req, res) => { const sig = req.headers['x-razorpay-signature']; const body = req.rawBody; const expected = crypto .createHmac('sha256', process.env.RAZORPAY_WEBHOOK_SECRET) .update(body) .digest('hex'); if (sig !== expected) return res.status(400).end(); // idempotency check before processing const { event, payload } = req.body; processPaymentEvent(event, payload); res.json({ status: 'ok' }); });
Secure order flow: server creates order → client opens checkout → server verifies signature. Zero raw keys on frontend.
// Fetch order from your server first const order = await fetch('/api/create-order', { method: 'POST', body: JSON.stringify({ amount: 49900, currency: 'INR' }) }).then(r => r.json()); const rzp = new Razorpay({ key: 'rzp_live_XXXXXXXXXXXX', order_id: order.id, amount: order.amount, currency: 'INR', name: 'Your Brand', handler: (response) => { // send to server for sig verification verifyPayment(response); } }); rzp.open();
One integration roadmap won't serve both markets — here's how we architect for both.
Proven combinations across 30+ Razorpay projects — no experiments in production.
Every sector has different Razorpay product needs — we know which one solves what.
Full Razorpay Subscriptions setup — free trials, multiple plan tiers, usage-based overages, and UPI AutoPay NACH mandates. Churn recovery via smart dunning email sequences tied to webhook failures.
Standard checkout with COD + Prepaid options, Razorpay Magic Checkout for 1-click repeat buyers, and EMI on high-ticket items. Returns and refunds handled via the Refunds API with customer notification hooks.
Razorpay Route for split payments between buyers and multiple sellers/freelancers. Linked account KYC onboarding, transfer hold rules, and real-time settlement dashboards for vendors.
Patient payment links via Razorpay Payment Pages, EMI for high-cost treatments, and recurring billing for subscription health plans. ABDM-aware invoice structure for insurance reimbursements.
Four focused phases — from API keys to production go-live in two weeks.
We map your business logic to the right Razorpay products — Subscriptions vs Orders API, Route vs Payouts, Smart Collect vs Payment Links. We define webhook event taxonomy, idempotency strategy, and database schema for payment ledger before writing a single line.
Full integration built against Razorpay's test environment — including edge cases: card decline codes, webhook retry storms, partial refunds, mandate cancellations. We use Razorpay's test payment simulator plus ngrok for local webhook delivery, so every scenario is covered before we touch production.
HMAC signature verification, rate limiting on webhook endpoints, idempotency key store in Redis, GST invoice templates with your GSTIN, and Sentry error alerting configured. We also set up Razorpay dashboard alerts for payment failure spikes and settlement delays.
Staged go-live with 24-hour monitoring. We run the first reconciliation cycle (Razorpay settlement vs your DB) to confirm zero discrepancies. You get a Loom walkthrough of the full system, webhook log interpretation guide, and a 30-day support window post-launch.
Answers from 30+ integrations across SaaS, e-commerce, and marketplaces.
"We tried implementing Razorpay Subscriptions in-house and spent two months debugging webhook edge cases. CodeByZeno came in, rebuilt the entire payment layer in 12 days, and we've had zero payment failures in 8 months. The GST invoicing automation alone saves us 6 hours a week."
30+ integrations. Zero payment failures post-launch. GST invoicing, UPI AutoPay, and Route payouts — all production-hardened.
