Razorpay Integration Guide: 5 Mistakes That Break Payments

Source: Dev.to

Many developers can open the checkout page, but still run into issues such as:

• ❌ Payments not verifying
• ❌ Incorrect amounts being charged
• ❌ Successful payments not recorded
• ❌ Order status not updating

After fixing multiple Razorpay integrations, I noticed something interesting:

Most payment failures happen because of a few small mistakes.

In this guide you’ll learn the 5 most common Razorpay integration mistakes — and how to avoid them.

Razorpay Payment Flow (Overview)

Before looking at the mistakes, it’s important to understand the correct payment flow.

    A[User clicks Pay] --> B[Frontend sends request to Backend]
    B --> C[Backend creates order using Razorpay API]
    C --> D[Order ID returned to Frontend]
    D --> E[Frontend opens Razorpay Checkout]
    E --> F[User completes payment]
    F --> G[Frontend sends payment details to Backend]
    G --> H[Backend verifies payment signature]
    H --> I[Payment confirmed]

Key Principles

• ✔ Orders should be created on the backend.
• ✔ Checkout runs on the frontend.
• ✔ Payment verification must happen on the backend.

This separation ensures security and reliability.

❌ Mistake #1: Creating Orders on the Frontend

A very common mistake is trying to create Razorpay orders directly from the frontend.

❌ Wrong Approach

// frontend (DO NOT DO THIS)
fetch("https://api.razorpay.com/v1/orders")

This exposes your secret API key, which is extremely dangerous. Anyone could inspect the code and misuse it.

✅ Correct Approach

Orders should always be created on the backend.

// backend (Node.js example)
const Razorpay = require("razorpay");

const razorpay = new Razorpay({
  key_id: process.env.RAZORPAY_KEY_ID,
  key_secret: process.env.RAZORPAY_KEY_SECRET,
});

const order = await razorpay.orders.create({
  amount: 50000,          // amount in paise
  currency: "INR",
  receipt: "receipt_123",
});

Secure Order Creation Flow

    A[User clicks Pay] --> B[Frontend requests backend to create order]
    B --> C[Backend calls Razorpay API]
    C --> D[Razorpay returns Order ID]
    D --> E[Backend sends Order ID to frontend]
    E --> F[Checkout opens]

❌ Mistake #2: Using the Wrong Amount Format

Razorpay expects the amount in paise, not rupees. This tiny detail causes many integrations to fail.

❌ Incorrect Example

amount: 500   // ❌ This is 500 INR, but Razorpay expects paise

✅ Correct Example

amount: 500 * 100   // ✅ 500 INR → 50000 paise

If the customer needs to pay ₹500, Razorpay expects:

50000   // 500 × 100

Amount Conversion Flow

flowchart TD
    A[Customer payment: 500 INR] --> B[Convert to paise]
    B --> C[500 × 100]
    C --> D[Send 50000 to Razorpay]

Rule to remember

Amount sent to Razorpay = Rupees × 100

❌ Mistake #3: Skipping Payment Verification

Many developers assume that if Razorpay Checkout shows “Payment Successful”, the payment is complete. That is not enough proof.

You must verify the payment signature on your backend.

Payment Verification Flow

flowchart TD
    A[User completes payment] --> B[Razorpay sends payment response to frontend]
    B --> C[Frontend sends payment_id, order_id, signature to backend]
    C --> D[Backend verifies signature using Razorpay secret key]
    D --> E[Backend confirms payment]

Without verification, attackers could fake payment responses.

❌ Mistake #4: Not Implementing Webhooks

Relying only on the frontend response works during testing, but in production payments can be:

• delayed
• retried
• refunded
• partially captured

Webhooks notify your backend when these events happen.

Webhook Event Flow

flowchart TD
    A[Payment event occurs on Razorpay] --> B[Razorpay sends webhook request]
    B --> C[Your backend webhook endpoint receives event]
    C --> D[Backend updates database]
    D --> E[Order status updated]

Common webhook events include:

payment.captured
payment.failed
refund.processed

Without webhooks, your backend won’t know the real payment state.

❌ Mistake #5: Using Test Keys in Production

This mistake happens more often than you think. During development Razorpay provides test API keys. If those keys are deployed to production, real payments will fail.

Environment Variables

RAZORPAY_KEY_ID=
RAZORPAY_KEY_SECRET=

Deployment Flow

flowchart TD
    A[Development] --> B[Use Razorpay Test Keys]
    B --> C[Testing completed]
    C --> D[Switch to Live Keys]
    D --> E[Deploy to Production]

Always double‑check the keys before deployment.

Final Thoughts

Payment integrations rarely fail because of complex code. They fail because of small details developers overlook, such as:

• Creating orders on the wrong layer
• Sending incorrect amounts
• Skipping payment verification
• Ignoring webhooks
• Deploying with test credentials

By following the patterns outlined above, you can build a secure, reliable Razorpay integration that works flawlessly in production. Happy coding!

## Common Razorpay Integration Mistakes

- Ignoring webhooks  
- Deploying with test keys  

Fixing these five mistakes will make your Razorpay integration:

- ✅ Secure  
- ✅ Reliable  
- ✅ Production‑ready
