This section will take you through the steps to add PayPal as a payment method on the storefront. It includes the steps necessary when using one of Medusa’s official storefronts as well as your own custom React-based storefront.
### Storefront Prerequisites
All storefronts require that you obtain your PayPal Client ID. You can retrieve it from your PayPal developer dashboard.
### Process Overview
Aside from the Next.js Storefront, you need to add the implementation with PayPal manually.
:::note
It is recommended to read through the [Frontend Checkout Flow](/advanced/storefront/how-to-implement-checkout-flow) first to fully understand how payment is implemented on the storefront.

Although the next sections have different implementations to add PayPal into your storefront, they essentially follow the same process:
1. Show PayPal’s button if the PayPal provider is available for the current cart.
2. When the button is clicked, open PayPal’s payment portal and wait for the customer to authorize the payment.
3. If the payment is authorized successfully, set PayPal’s [Payment Session](../advanced/backend/payment/overview.md#payment-session) as the session used to perform the payment for the current cart, then update the Payment Session on the server with the data received from PayPal’s payment portal. This data is essential to the server to verify the authorization and perform additional payment processing later such as capturing payment.
4. Complete the cart to create the order.
:::note
:::info
In Medusa, by default, payments are authorized during checkout, but the payment is not captured right away. The payment should be manually [captured from the Medusa Admin](#capture-payment).

## Next.js Storefront
### Add to Next.js Storefront
Medusa has a Next.js storefront that you can easily use with your Medusa server. If you don’t have the storefront installed, you can follow [this quickstart guide](../starters/nextjs-medusa-starter.md).
In your `.env.local` file (or the file you’re using for your environment variables), add the following variable with its value set to the Client ID:
In your `.env.local` file (or the file you’re using for your environment variables), add the following variable:
```bash
NEXT_PUBLIC_PAYPAL_CLIENT_ID=<CLIENT_ID>
NEXT_PUBLIC_PAYPAL_CLIENT_ID=<YOUR_CLIENT_ID>
```
Then, install [PayPal’s React components](https://www.npmjs.com/package/@paypal/react-paypal-js) library:
Make sure to replace `<YOUR_CLIENT_ID>` with your PayPal Client ID.
```bash npm2yarn
npm install @paypal/react-paypal-js
```
Now, if you run your Medusa server and your storefront, on checkout you’ll be able to use PayPal].
Next, create a new file `components/checkout/paypal.jsx` with the following content:
```jsx
import { PayPalButtons, PayPalScriptProvider } from "@paypal/react-paypal-js";
import React, { useContext, useState } from "react";
import { BiLeftArrowAlt } from "react-icons/bi";
import DisplayContext from "../../context/display-context";
import StoreContext from "../../context/store-context";
import { createClient } from "../../utils/client"
import styles from "../../styles/injectable-payment-card.module.css";
import { useRouter } from "next/router";
const paypalClientId = process.env.NEXT_PUBLIC_PAYPAL_CLIENT_ID || ""
const Paypal = () => {
const [error, setError] = useState(null);
const [processing, setProcessing] = useState("");
const { cart, setPaymentSession } = useContext(StoreContext);
const { updateCheckoutStep } = useContext(DisplayContext);
const router = useRouter();
const client = createClient()
const handleSubmit = async (data, actions) => {
actions.order.authorize().then(async (authorization) => {
if (authorization.status !== 'COMPLETED') {
setError(`An error occurred, status: ${authorization.status}`);
setProcessing(false);
return;
}
const { cart } = await setPaymentSession("paypal")
if (!cart) {
setProcessing(false)
return
}
await client.carts.updatePaymentSession(cart.id, "paypal", {
data: {
data: {
...authorization
}
}
});
setError(null);
setProcessing(false);
router.push(`/payment`);
})
};
return (
<>
<PayPalScriptProvider options={{
"client-id": paypalClientId,
"currency": cart.region.currency_code.toUpperCase(),
"intent": "authorize"
}}>
{error && (
<span className="text-rose-500 mt-4">{error}</span>
)}
<PayPalButtons
style={{ layout: "horizontal" }}
onApprove={handleSubmit}
disabled={processing}
/>
</PayPalScriptProvider>
<button
className={styles.stepBack}
onClick={() => updateCheckoutStep(2)}
>
<BiLeftArrowAlt /> Back to shipping method
</button>
</>
)
}
export default Paypal
```
Here’s briefly what this code snippet does:
1. This component renders a PayPal button to initialize the payment using PayPal. You use the components from the PayPal React components library to render the button and you pass the `PayPalScriptProvider` component the Client ID.
2. When the button is clicked, the `handleSubmit` function is executed. In this method, you initialize the payment authorization using `actions.order.authorize()`. It takes the customer to another page to log in with PayPal and authorize the payment.
3. After the payment is authorized successfully on PayPal’s portal, the fulfillment function passed to `actions.order.authorize().then` will be executed.
4. In the fulfillment function, you first ensure that the payment session for the PayPal payment provider is set as the [selected Payment Session in the cart](https://docs.medusajs.com/api/store/cart/select-a-payment-session). Then, you send a request to the server to [update the payment session](https://docs.medusajs.com/api/store/cart/update-a-payment-session) data with the authorization data received from PayPal.
5. After all that is done successfully, you navigate to the `/payment` page which will automatically [complete the cart and place the order](https://docs.medusajs.com/api/store/cart/complete-a-cart).
The last step is to add this component as the component to render when PayPal is available as a payment provider.
In `src/checkout/payment-step.jsx` you’ll find in the return statement a switch statement that checks the payment provider for each payment session and renders the component based on the ID. Add before the `default` case a case for `paypal`:
```jsx
switch (ps.provider_id) {
case "stripe":
//..
case "manual":
//...
case "paypal":
return (
<div key="paypal">
<h2>PayPal Payment</h2>
<Paypal />
</div>
)
default:
return null;
}
```
Make sure to also import the `Paypal` component at the top of the file:
```jsx
import Paypal from "./paypal";
```
That’s all you need to integrate PayPal into the Next.js storefront.
Now, start the Medusa server and the Next.js storefront server. Try adding an item into the cart and proceeding to checkout. When you reach the payment step, you should see the PayPal button.
