Better Auth Razorpay Plugin – Payments, Subscriptions & Webhooks

Better Auth Razorpay Plugin

A comprehensive Razorpay integration for Better Auth that brings payment processing, recurring billing, and payment operations into a unified TypeScript plugin. It connects Better Auth's authentication and database ecosystem with Razorpay's APIs, reducing the amount of custom payment infrastructure application teams need to maintain.

Overview

Payment integration involves more than opening a checkout window. Production applications need order creation, server-side verification, refunds, subscription lifecycle management, invoices, customer records, marketplace transfers, and reliable webhook processing.

Better Auth Razorpay brings these capabilities behind Better Auth plugin endpoints and optional React Query hooks.

Highlights

• One-time order creation, payment verification, capture, and refunds
• Subscription creation and lifecycle management
• Invoice, plan, item, and add-on operations
• Customer records, bank accounts, and saved payment-token management
• Razorpay Route transfers, holds, and reversals
• Verified webhook handling with event-specific callbacks
• Better Auth database schema integration for users, organizations, and subscriptions
• Optional TanStack Query hooks for React applications

Architecture

The plugin sits between the application and Razorpay. The Better Auth server handles authenticated requests, the Razorpay plugin exposes payment routes and invokes the Razorpay SDK, and the database stores application-side customer and subscription information. Razorpay webhooks deliver asynchronous payment and billing events back to the plugin.

Payment verification flow

The plugin includes HMAC-SHA256 payment signature verification and a separate status-validation helper. The latter checks the fetched payment's order association, optional expected amount, and captured status. Applications should perform verification on the server and use webhook events as part of reliable fulfillment.

Checkout sequence

Core capabilities

One-time payments

Create Razorpay orders with amount, currency, receipt, notes, and supported partial-payment options. The plugin also exposes payment retrieval, listing, capture, editing, and refund operations.

Amounts use the smallest currency unit: for INR, 50000 represents ₹500.

Example:

tsCopy
const order = await auth.api.razorpayCreateOrder({
  body: {
    amount: 50000,
    currency: "INR",
    receipt: "receipt_001",
  },
});

Subscription billing

Subscription functionality includes plan configuration, creation or upgrade, retrieval, updates, pause and resume, cancellation, restoration, pending updates, invoices, and add-ons. Subscription data is represented in the Better Auth database and can be associated with a user or organization.

Webhooks

The plugin verifies webhook signatures and maps Razorpay events to callbacks. Supported event families include payment authorized/captured/failed, order paid, refund created/processed/failed, invoice paid/partially paid/expired, and subscription authentication, activation, charge, cancellation, pause, resume, halt, pending, completion, update, renewal, and offer-update events. A generic onEvent callback is also available.

Webhook consumers should make fulfillment and synchronization idempotent because providers may retry event delivery.

Invoices, refunds, and customers

Invoice operations cover creation, retrieval, editing, issuance, notification, cancellation, and deletion. Refund operations include initiation and refund retrieval/listing/editing. Customer operations include create, update, list, retrieval, bank-account management, and saved-token management.

Marketplace transfers

For eligible Razorpay Route accounts, the plugin supports creating transfers to linked accounts, applying settlement holds, retrieving and editing transfers, and reversing transfers.

React Query hooks

The optional React entry point provides TanStack Query hooks for subscriptions, payments, refunds, invoices, orders, customers, add-ons, and items. Structured query keys support cache management and invalidation.

tsxCopy
import {
  useSubscriptionList,
  useUpgradeSubscription,
} from "@amank-root/better-auth-razorpay/react";

function BillingPage() {
  const { data, isLoading } = useSubscriptionList(authClient);
  const upgrade = useUpgradeSubscription(authClient);

  if (isLoading) return <p>Loading...</p>;

  return (
    <>
      {data?.map((subscription) => (
        <p key={subscription.id}>{subscription.plan}</p>
      ))}
      <button onClick={() => upgrade.mutate({ plan: "pro", annual: true })}>
        Upgrade
      </button>
    </>
  );
}

Getting started

Install the package:

bashCopy
npm install @amank-root/better-auth-razorpay

Register the plugin with Better Auth on the server:

tsCopy
import { betterAuth } from "better-auth";
import { razorpayPlugin } from "@amank-root/better-auth-razorpay";

export const auth = betterAuth({
  database: yourDatabaseConfig,
  plugins: [
    razorpayPlugin({
      keyId: process.env.RAZORPAY_KEY_ID!,
      keySecret: process.env.RAZORPAY_KEY_SECRET!,
      razorpayWebhookSecret: process.env.RAZORPAY_WEBHOOK_SECRET!,
      defaultCurrency: "INR",
    }),
  ],
});

Keep Razorpay secrets server-side. Configure the webhook endpoint and secret in the Razorpay dashboard, and apply the database schema changes required by the plugin. For subscription billing, enable the subscription option and configure Razorpay plan IDs. Refer to the repository README for the full configuration and API reference.

Security considerations

• Never expose Razorpay secret keys or webhook secrets to browser code.
• Verify payment signatures on the server.
• Validate the fetched payment's order association, amount, and captured status before fulfillment.
• Verify webhook signatures against the raw request body as required by the integration.
• Make webhook-driven side effects idempotent and handle retries safely.
• Use authenticated server routes and validate user or organization ownership for billing operations.

Technology stack

• TypeScript — implementation and typed APIs
• Better Auth — authentication and plugin framework
• Razorpay SDK — payment gateway integration
• Zod — request validation
• TanStack Query — React queries and mutations
• React — optional frontend hooks
• Node.js — server runtime
• Bun — package and development tooling
• Vitest — test suite
• tsup — package bundling

Who is it for?

SaaS products that need recurring plans and trials, marketplaces that need linked-account transfers, membership platforms that tie access to payment state, and full-stack teams that want a reusable Better Auth integration instead of repeatedly building payment plumbing.

Conclusion

Better Auth Razorpay provides a single integration surface for checkout, subscriptions, invoices, refunds, customer operations, transfers, and webhook-driven billing workflows. It is designed to make payment infrastructure easier to integrate into applications already using Better Auth.
