BillingSDK Integration

Reference:docs.dodopayments.com/developer-resources/billingsdk | billingsdk.com

BillingSDK provides open-source, customizable React components for billing interfaces - pricing tables, subscription management, usage meters, and more.

Overview

BillingSDK offers:

• React Components : Pre-built, customizable billing components
• CLI Tooling : Project initialization and component management
• Framework Support : Next.js, Express.js, Hono, Fastify, React
• Payment Provider : Full integration with Dodo Payments

Quick Start Options

Option 1: New Project (Recommended)

Complete project setup with framework configuration and API routes:

npx @billingsdk/cli init

The CLI will:

• Configure your framework (Next.js App Router)
• Set up Dodo Payments integration
• Generate API routes for checkout, customers, webhooks
• Install dependencies
• Create configuration files

Option 2: Add to Existing Project

Add individual components using the CLI:

npx @billingsdk/cli add pricing-table-one
npx @billingsdk/cli add subscription-management
npx @billingsdk/cli add usage-meter-circle

Option 3: Manual via shadcn/ui

Install directly using shadcn registry:

npx shadcn@latest add @billingsdk/pricing-table-one

CLI Reference

Initialize Project

npx @billingsdk/cli init

Interactive setup prompts:

1. Select framework (Next.js, Express.js, Hono, Fastify, React)
2. Select payment provider (Dodo Payments)
3. Configure project settings

Add Components

npx @billingsdk/cli add <component-name>

Available components:

• pricing-table-one - Simple pricing table
• pricing-table-two - Feature-rich pricing table
• subscription-management - Manage active subscriptions
• usage-meter-circle - Circular usage visualization
• More components available...

What happens when adding:

1. Downloads component from registry
2. Installs files to components/billingsdk/
3. Updates project configuration
4. Installs additional dependencies

Components

      />
      <UsageMeterCircle 
        label="Storage"

Generated API Routes

Checkout Route (app/api/checkout/route.ts):

import { NextRequest, NextResponse } from 'next/server';
import { dodo } from '@/lib/dodo';

export async function POST(req: NextRequest) {
  const { productId, email } = await req.json();

  const session = await dodo.checkoutSessions.create({
    product_cart: [{ product_id: productId, quantity: 1 }],
    customer: { email },
    return_url: `${process.env.NEXT_PUBLIC_APP_URL}/success`,
  });

  return NextResponse.json({ checkoutUrl: session.checkout_url });
}

Portal Route (app/api/portal/route.ts):

import { NextRequest, NextResponse } from 'next/server';
import { dodo } from '@/lib/dodo';
import { getSession } from '@/lib/auth';

export async function POST(req: NextRequest) {
  const session = await getSession();
  
  const portal = await dodo.customers.createPortalSession({
    customer_id: session.user.customerId,
    return_url: `${process.env.NEXT_PUBLIC_APP_URL}/account`,
  });

  return NextResponse.json({ url: portal.url });
}

Configuration File

lib/billingsdk-config.ts:

export const plans = [
  {
    id: process.env.NEXT_PUBLIC_PLAN_FREE_ID!,
    name: 'Free',
    description: 'Perfect for trying out',
    price: 0,
    interval: 'month' as const,
    features: [
      '5 projects',
      '1 GB storage',
      'Community support',
    ],
  },
  {
    id: process.env.NEXT_PUBLIC_PLAN_PRO_ID!,
    name: 'Pro',
    description: 'For professionals',
    price: 29,
    interval: 'month' as const,
    popular: true,
    features: [
      'Unlimited projects',
      '50 GB storage',
      'Priority support',
      'API access',
    ],
  },
];

export const config = {
  returnUrl: process.env.NEXT_PUBLIC_APP_URL + '/success',
  portalReturnUrl: process.env.NEXT_PUBLIC_APP_URL + '/account',
};

Customization

Styling with Tailwind

Components use Tailwind CSS and shadcn/ui patterns. Customize via:

1. Theme variables in globals.css
2. Direct class overrides on components
3. Component source modification (files are local)

Example - Custom colors:

/* globals.css */
@layer base {
  :root {
    --primary: 220 90% 56%;
    --primary-foreground: 0 0% 100%;
  }
}

Component Props

Most components accept standard styling props:

<PricingTableOne 
  plans={plans}
  onSelectPlan={handleSelect}
  className="max-w-4xl mx-auto"
  containerClassName="gap-8"
  cardClassName="border-2"
/>

Environment Variables

# .env.local

# Dodo Payments
DODO_PAYMENTS_API_KEY=sk_live_xxxxx
DODO_PAYMENTS_WEBHOOK_SECRET=whsec_xxxxx

# Product IDs (from dashboard)
NEXT_PUBLIC_PLAN_FREE_ID=prod_xxxxx
NEXT_PUBLIC_PLAN_PRO_ID=prod_xxxxx
NEXT_PUBLIC_PLAN_ENTERPRISE_ID=prod_xxxxx

# App
NEXT_PUBLIC_APP_URL=https://yoursite.com

Best Practices

1. Use Product IDs from Environment

Keep product IDs in environment variables for easy staging/production switching.

2. Handle Loading States

Components should show loading states during checkout:

const [loading, setLoading] = useState(false);

const handleSelect = async (planId: string) => {
  setLoading(true);
  try {
    const response = await fetch('/api/checkout', {...});
    const { checkoutUrl } = await response.json();
    window.location.href = checkoutUrl;
  } finally {
    setLoading(false);
  }
};

3. Server-Side Data Fetching

Fetch subscription data server-side when possible:

// app/account/page.tsx
import { getSubscription } from '@/lib/subscription';

export default async function AccountPage() {
  const subscription = await getSubscription();
  
  return <SubscriptionManagement subscription={subscription} />;
}

4. Implement Webhooks

Always use webhooks as source of truth for subscription status, not client-side data.
