Set Environment Variables

Add the following environment variables to your .env.local file:

# Paddle Configuration
PADDLE_SANDBOX=true                               # Use sandbox mode for development

​
Get Paddle Credentials

  1. Log in to your Paddle Dashboard
  2. Navigate to Developer Tools > Authentication
  3. Copy your API Key
  4. Get your Client Token - create one in Developer Tools > Clients

​
Product Configuration

​
Set Up Products in Paddle

  1. Navigate to Catalog > Products in the Paddle dashboard
  2. Click Create Product
  3. Fill in the product details and save
  4. Create product prices (at least one price per product)
  5. Note down the product ID and price ID

​
Update PreLaunch Configuration

In the config.ts file, update the configuration using the product and price IDs you created in Paddle:

// config.ts
paddle: {
  plans: [
    {
      priceId: "pri_xxxxxxxxxxxxxxxx",  // Price ID, starts with pri_
      isFeatured: true,
      icon: "/assets/icons/paddle-icon.svg",
      name: "Basic Plan",
      description: "Ideal for individuals and small teams",
      price: 99,
      priceAnchor: 149,  // Original price (for displaying discounts)
      features: [
        "Complete landing page template",
        "SEO optimization",
        "Waitlist functionality",
        "High performance loading",
        // Other features...
      ],
    },
    // More pricing plans...
  ],
}

​
Using Paddle Checkout

PreLaunch provides two ways to use Paddle checkout:

​
1. Using the Pre-built Checkout Button

The simplest method is to use the built-in ButtonCheckout component:

import { ButtonCheckout } from '@/components/ButtonCheckout';

export default function PricingSection() {
  return (
    <div className="pricing-card">
      <h3>Basic Plan</h3>
      <p>Ideal for individuals and small teams</p>
      <p className="price">$99</p>
      
      {/* Paddle checkout button */}
      <ButtonCheckout priceId="pri_xxxxxxxxxxxxxxxx" />
    </div>
  );
}

​
2. Using the Paddle.js API

If you need more customization options, you can directly use the Paddle.js API:

import { usePaddle } from '@/hooks/usePaddle';

export default function CustomCheckout() {
  const { checkout } = usePaddle();
  
  const handleCheckout = () => {
    checkout({
      priceId: 'pri_xxxxxxxxxxxxxxxx',
      quantity: 1,
      customerEmail: 'user@example.com', // Optional
      successUrl: 'https://yourdomain.com/thank-you', // Optional
      // Other options...
    });
  };
  
  return (
    <button onClick={handleCheckout}>
      Buy Now
    </button>
  );
}

​
Webhook Setup

To handle Paddle events (such as successful payments, subscription status changes, etc.), you need to set up a webhook:

  1. Navigate to Developer Tools > Webhooks in the Paddle dashboard
  2. Create a new webhook endpoint with the URL: https://yourdomain.com/api/paddle/webhook
  3. Select the events you want to receive (at minimum: subscription.activated, subscription.cancelled, payment.succeeded)
  4. Copy the generated webhook secret to your .env.local file: PADDLE_NOTIFICATION_WEBHOOK_SECRET

For detailed setup instructions, please refer to the PADDLE-WEBHOOK-SETUP.md file.

​
Customer Account Management

PreLaunch includes a customer account management component that allows users to view and manage their subscriptions:

import { ButtonPaddleAccount } from '@/components/ButtonPaddleAccount';

export default function AccountPage() {
  return (
    <div className="account-page">
      <h1>Your Account</h1>
      
      {/* Paddle customer account management */}
      <ButtonPaddleAccount />
    </div>
  );
}

​
Local Development Notes

In your local development environment:

  1. Set PADDLE_SANDBOX=true in your .env.local file
  2. Use product and price IDs created in the Paddle sandbox environment
  3. Note that webhooks need a publicly accessible URL; you can use tools like ngrok to create a temporary public URL for testing webhooks

​
Troubleshooting

​
Production Deployment

When you’re ready to deploy to production:

  1. Create production environment products and pricing plans in Paddle
  2. Update environment variables, set PADDLE_SANDBOX=false
  3. Use production environment API keys and client tokens
  4. Update the webhook URL to point to your production domain
