Important: If you're totally new to Next.js and Paddle, we have a more complete tutorial on our dev docs: Build and deploy Next.js app with Vercel and Supabase
Click this button to clone this repo and create a new project in your Vercel account:
You can also create a new application manually.
Configure projectClick Add to walk through integrating with Supabase. You'll be asked to authenticate with Supabase and confirm creating the database schemas.
Then, enter Paddle environment variables:
Variable | Used for | How to get it |
---|---|---|
PADDLE_API_KEY | An API key, used for interacting with Paddle data in the backend. For example, syncing customer and subscription data with Supabase. | Go to Paddle > Developer tools > Authentication and create a new API key. |
NEXT_PUBLIC_PADDLE_CLIENT_TOKEN | A client-side key, used for interacting with Paddle in the frontend. For example, getting localized prices for pricing pages and opening a checkout. | Go to Paddle > Developer tools > Authentication and create a new client-side token. |
PADDLE_NOTIFICATION_WEBHOOK_SECRET | A secret key used for verifying that webhooks came from Paddle and haven't been tampered with in transit. Important for security. | Go to Paddle > Developer tools > Notifications, create a new notification destination for your Vercel deploy URL + /api/webhook , then edit to copy the secret key. See below for more information. |
NEXT_PUBLIC_PADDLE_ENV | Environment for our Paddle account. This should match the kind of Paddle account you signed up for. | Enter sandbox for sandbox accounts or production for live accounts. |
Use https://<PROJECTNAME>.vercel.app/api/webhook
as the endpoint URL for your notification destination, where <PROJECTNAME>
is the name of your project in Vercel. For example, https://paddle-billing.vercel.app/api/webhook
.
If your project name isn't unique, your Vercel deploy URL may not match the URL you enter here. We can review and update this after deploy.
DeployClick Deploy when you're done. Wait for Vercel to build.
Clone the repository you created earlier.
git clone https://github.com/PATH_TO_YOUR_REPO
Install dependencies using npm, Yarn, or pnpm.
Install using npm:
npm install
Install using Yarn:
yarn install
Install using pnpm:
pnpm install
Create products and prices in Paddle for your subscription plans. We recommend creating three products for your plans, with two prices for each product to describe how you bill. For example, create a product called "Pro plan" with two prices for "monthly" and "annual."
Next, copy your price IDs and update the pricing-tier.ts
constants file with your new prices.
Commit and push your changes to main
.
You must add URLs to Paddle before you can launch a checkout from them. This protects you as a seller, making sure that only you're able to sell your products.
TestImportant: Website approval is instant for sandbox accounts, but may take a little while for live accounts while the Paddle seller verification team check your website.
Open your Vercel demo site. You should notice that Paddle returns the prices you entered for each of your plans on your pricing page.
Click Get started to launch a checkout for a plan, then take a test payment.
If you're using a sandbox account, you can take a test payment using our test card details:
Field | Value |
---|---|
Email address | An email address you own |
Country | Any valid country supported by Paddle |
ZIP code (if required) | Any valid ZIP or postal code |
Card number | 4242 4242 4242 4242 |
Name on card | Any name |
Expiration date | Any valid date in the future. |
Security code | 100 |
After checkout is completed, head back to the homepage and click Sign in. Have a look at the subscriptions and payments pages. They pull information from Paddle about a customer's subscriptions and transactions.
You're done! 🎉 You can use this starter kit as a basis for building a SaaS app powered by Paddle Billing.
Once you've built your app, transition to a live account to start taking real payments:
