⚙️ Setup — 5 steps

1. Add the plugin to Copy to clipboardmedusa-config.ts

1234567891011121314151617181920
import { loadEnv, defineConfig } from "@medusajs/framework/utils"

loadEnv(process.env.NODE_ENV || "development", process.cwd())

export default defineConfig({
  projectConfig: {
    databaseUrl: process.env.DATABASE_URL,
    http: {
      storeCors: process.env.STORE_CORS!,
      adminCors: process.env.ADMIN_CORS!,
      authCors: process.env.AUTH_CORS!,
      jwtSecret: process.env.JWT_SECRET || "supersecret",
      cookieSecret: process.env.COOKIE_SECRET || "supersecret",
    },
  },

  plugins: [
    {
      resolve: "@easypayment/medusa-payment-paypal",
      options: {},

2. Run database migrations

1
npx medusa db:migrate

3. Connect your PayPal account

1. Start your Medusa server
2. Open Medusa Admin → Settings → PayPal
3. Choose Sandbox (testing) or Live (real payments)
4. Click Connect to PayPal and follow the steps

That's it — your credentials are saved automatically. Webhooks are registered for you too.

💡 Prefer manual setup? Click Insert credentials manually and paste your Client ID and Secret from developer.paypal.com.

4. Turn PayPal on in your region

Go to Medusa Admin → Settings → Regions → your region and enable:

Payment provider What it is Copy to clipboardpp_paypal_paypal PayPal Buttons Copy to clipboardpp_paypal_card_paypal_card Card payments

5. Add PayPal to your storefront

The checkout UI comes as a separate package — install it in your storefront project:

📦 @easypayment/medusa-paypal-ui — ready-made PayPal components for Next.js storefronts, with a step-by-step guide.

🎨 Customize (optional)

Everything is managed in Medusa Admin → Settings → PayPal — changes apply instantly, no restart needed:

• PayPal Settings — turn PayPal on/off, button color, shape, and label
• Advanced Card Payments — turn card payments on/off, 3D Secure mode
• Additional Settings — capture vs. authorize, brand name shown at PayPal, invoice prefix

🔐 Going live — two things we recommend

1. Copy to clipboardPAYPAL_ENCRYPTION_KEY — set this to any long random text in your server's environment. Your PayPal credentials are then stored encrypted in the database. Keep the key safe: if it's lost, just reconnect PayPal.
2. Copy to clipboardMEDUSA_BACKEND_URL — set this to your backend's public address (e.g. Copy to clipboardhttps://api.mystore.com) so PayPal can reach your store for payment notifications.
