react-paypal-js

React components for the PayPal JS SDK

Are you still using the old PayPal JS SDK V5 SDK?

This documentation teaches how to use the latest PayPal JS SDK with react. For the integration using PayPal JS SDK V5 with PayPalScriptProvider, PayPalButtons, PayPalHostedFields, and BraintreePayPalButtons, see README-PAYPAL-JS-SDK-V5.md.

Integrating PayPal into React applications requires careful handling of SDK script loading, payment session management, and UI rendering. Building a robust integration from scratch can lead to issues with timing, state management, and buyer experience.

The Solution

react-paypal-js provides a modern, hooks-based solution that abstracts away the complexities of the PayPal V6 SDK. It enforces best practices by default to ensure buyers get the best possible user experience.

Features

Modern Hooks API - Fine-grained control over payment sessions with usePayPalOneTimePaymentSession, useVenmoOneTimePaymentSession, and more
Built-in Eligibility - Automatically check which payment methods are available with useEligibleMethods()
Web Component Buttons - Use PayPal's optimized <paypal-button>, <venmo-button>, and <paypal-pay-later-button> web components
Flexible Loading - Support for string token/id, Promise-based token/id, and deferred loading patterns
TypeScript Support - Complete type definitions for all components and hooks
SSR Compatible - Built-in hydration handling for server-side rendered applications

Supported Payment Methods

PayPal - Standard PayPal checkout
Venmo - Venmo payments
Pay Later - PayPal's buy now, pay later option
PayPal Basic Card - Guest card payments without a PayPal account
PayPal Advanced Card - Card payments with enhanced features and customization options
PayPal Subscriptions - Recurring billing subscriptions
PayPal Save - Vault payment methods without purchase
PayPal Credit - PayPal Credit one-time and save payments
Google Pay - Native Google Pay button flow through PaymentsClient
Apple Pay - Native Apple Pay payments (Safari + HTTPS only)

Installation

npm install @paypal/react-paypal-js

Quick Start

import {
  PayPalProvider,
  PayPalOneTimePaymentButton,
} from "@paypal/react-paypal-js/sdk-v6";

function App() {
  return (
    <PayPalProvider
      clientId="your-client-id"
      environment="sandbox"
      components={["paypal-payments"]}
      pageType="checkout"
    >
      <CheckoutPage />
    </PayPalProvider>
  );
}

function CheckoutPage() {
  return (
    <PayPalOneTimePaymentButton
      createOrder={async () => {
        const response = await fetch("/api/create-order", {
          method: "POST",
        });
        const { orderId } = await response.json();
        return { orderId };
      }}
      onApprove={async ({ orderId }: OnApproveDataOneTimePayments) => {
        await fetch(`/api/capture-order/${orderId}`, {
          method: "POST",
        });
        console.log("Payment captured!");
      }}
    />
  );
}

PayPalProvider

The PayPalProvider component is the entry point for the V6 SDK. It handles loading the PayPal SDK, creating an instance, and running eligibility checks.

Props

Prop	Type	Required	Description
`clientToken`	`string \| Promise<string>`	*	Client token from your server. Mutually exclusive with `clientId`.
`clientId`	`string \| Promise<string>`	*	Client ID from your PayPal app. Mutually exclusive with `clientToken`.
`components`	`Components[]`	No	SDK components to load. Defaults to `["paypal-payments"]`.
`pageType`	`string`	No	Type of page: `"checkout"`, `"product-details"`, `"cart"`, `"product-listing"`, etc.
`locale`	`string`	No	Locale for the SDK (e.g., `"en_US"`).
`environment`	`"sandbox" \| "production"`	Yes	Required. SDK environment. `clientId` does not select the environment in v6 — this prop does.
`merchantId`	`string \| string[]`	No	PayPal merchant ID(s).
`clientMetadataId`	`string`	No	Client metadata ID for tracking.
`partnerAttributionId`	`string`	No	Partner attribution ID (BN code).
`shopperSessionId`	`string`	No	Shopper session ID for tracking.
`testBuyerCountry`	`string`	No	Test buyer country code (sandbox only).
`debug`	`boolean`	No	Enable debug mode.
`dataNamespace`	`string`	No	Custom namespace for the SDK script data attribute.
`eligibleMethodsResponse`	`FindEligiblePaymentMethodsResponse`	No	Server-fetched eligibility response for SDK hydration (see Server-Side Rendering).

* Either clientToken or clientId is required, but not both. They are mutually exclusive.

Available Components

The components prop accepts an array of the following values:

"paypal-payments" - PayPal and Pay Later buttons
"venmo-payments" - Venmo button
"paypal-guest-payments" - Guest checkout (card payments)
"paypal-subscriptions" - Subscription payments
"card-fields" - Card Fields (advanced card payment UI)
"googlepay-payments" - Google Pay

With Promise-based Client ID

function App() {
  // Memoize to prevent re-fetching on each render
  const clientIdPromise = useMemo(() => fetchClientId(), []);

  return (
    <PayPalProvider
      clientId={clientIdPromise}
      environment="sandbox"
      components={["paypal-payments"]}
      pageType="checkout"
    >
      <CheckoutPage />
    </PayPalProvider>
  );
}

Alternative: With Promise-based Client Token

function App() {
  // Memoize to prevent re-fetching on each render
  const tokenPromise = useMemo(() => fetchClientToken(), []);

  return (
    <PayPalProvider
      clientToken={tokenPromise}
      environment="sandbox"
      components={["paypal-payments"]}
      pageType="checkout"
    >
      <CheckoutPage />
    </PayPalProvider>
  );
}

Deferred Loading

function App() {
  const [clientId, setClientId] = useState<string>();

  useEffect(() => {
    fetchClientId().then(setClientId);
  }, []);

  return (
    <PayPalProvider
      clientId={clientId}
      environment="sandbox"
      components={["paypal-payments"]}
      pageType="checkout"
    >
      <CheckoutPage />
    </PayPalProvider>
  );
}

Tracking Loading State

Use the usePayPal hook to access the SDK loading status:

import {
  usePayPal,
  INSTANCE_LOADING_STATE,
} from "@paypal/react-paypal-js/sdk-v6";

function CheckoutPage() {
  const { loadingStatus, error } = usePayPal();

  if (loadingStatus === INSTANCE_LOADING_STATE.PENDING) {
    return <div className="spinner">Loading PayPal...</div>;
  }

  if (loadingStatus === INSTANCE_LOADING_STATE.REJECTED) {
    return (
      <div className="error">Failed to load PayPal SDK: {error?.message}</div>
    );
  }

  return <PayPalOneTimePaymentButton orderId="ORDER-123" />;
}

Button Components

PayPalOneTimePaymentButton

Renders a PayPal button for one-time payments.

import { PayPalOneTimePaymentButton } from "@paypal/react-paypal-js/sdk-v6";

<PayPalOneTimePaymentButton

Renders a Venmo button for one-time payments. Requires "venmo-payments" in the provider's components array.

import { VenmoOneTimePaymentButton } from "@paypal/react-paypal-js/sdk-v6";

<PayPalProvider
  clientId={clientId}
  environment="sandbox"
  components={["paypal-payments", "venmo-payments"]}
  pageType="checkout"
>
  <VenmoOneTimePaymentButton
    createOrder={async () => {

</PayPalProvider>;

GooglePayOneTimePaymentButton

Renders a native Google Pay button for one-time payments. Requires "googlepay-payments" in the provider's components array.

Google Pay prerequisites:

Load Google Pay JS in your app HTML shell (for example public/index.html):

<script async src="https://pay.google.com/gp/p/js/pay.js"></script>

Ensure the script is available before rendering GooglePayOneTimePaymentButton, since this component depends on window.google.payments.api.PaymentsClient.

import {
  PayPalProvider,
  GooglePayOneTimePaymentButton,
  useEligibleMethods,
  INSTANCE_LOADING_STATE,
  usePayPal,
} from "@paypal/react-paypal-js/sdk-v6";

function GooglePayCheckout() {
  const { loadingStatus } = usePayPal();
  const { eligiblePaymentMethods, isLoading } = useEligibleMethods({
    payload: { currencyCode: "USD" },
  });

  if (loadingStatus === INSTANCE_LOADING_STATE.PENDING || isLoading) {
    return <div>Loading Google Pay...</div>;
  }

  const googlePayConfig = eligiblePaymentMethods?.isEligible("googlepay")
    ? eligiblePaymentMethods.getDetails("googlepay").config
    : null;

  if (!googlePayConfig) {
    return <div>Google Pay is not eligible for this buyer.</div>;
  }

  return (
    <GooglePayOneTimePaymentButton
      googlePayConfig={googlePayConfig}
      transactionInfo={{
        countryCode: "US",
        currencyCode: "USD",
        totalPriceStatus: "FINAL",
        totalPrice: "100.00",
      }}
      createOrder={async () => {
        const response = await fetch("/api/create-order", { method: "POST" });
        const { orderId } = await response.json();
        return { orderId };
      }}
      onApprove={(data) => console.log("Google Pay approved", data)}
      onCancel={() => console.log("Google Pay cancelled")}
      onError={(error) => console.error("Google Pay error", error)}
      buttonType="pay"
      buttonColor="default"
      buttonSizeMode="fill"
    />
  );
}

function App() {
  return (
    <PayPalProvider
      clientId="your-client-id"
      environment="sandbox"
      components={["googlepay-payments"]}
      pageType="checkout"

PayLaterOneTimePaymentButton

Renders a Pay Later button for financing options. Country code and product code are automatically populated from eligibility data, so eligibility must be fetched first — via useEligibleMethods() client-side (shown below) or the provider's eligibleMethodsResponse prop server-side.

import {
  PayLaterOneTimePaymentButton,
  useEligibleMethods,
} from "@paypal/react-paypal-js/sdk-v6";

function PayLaterCheckout() {
  // Fetch eligibility first (or hydrate server-side via eligibleMethodsResponse)
  const { eligiblePaymentMethods, isLoading } = useEligibleMethods({
    payload: { purchase_units: [{ amount: { currency_code: "USD" } }] },
  });

  if (isLoading) {
    return <Spinner />;
  }
  if (!eligiblePaymentMethods?.isEligible("paylater")) {
    return null;
  }

  return (
    <PayLaterOneTimePaymentButton
      createOrder={async () => {
        const { orderId } = await createOrder();
        return { orderId };
      }}
      onApprove={(data: OnApproveDataOneTimePayments) =>
        console.log("Pay Later approved!", data)
      }
      onCancel={(data: OnCancelDataOneTimePayments) =>
        console.log("Pay Later cancelled", data)
      }
      onError={(data: OnErrorData) => console.error("Pay Later error:", data)}
      onComplete={(data: OnCompleteData) =>

      }
    />
  );
}

PayPalGuestPaymentButton

Renders a guest checkout button for card payments without a PayPal account (Branded Card/Debit Card checkout). Requires "paypal-guest-payments" in the provider's components array.

  clientId={clientId}
  environment="sandbox"
  components={["paypal-payments", "paypal-guest-payments"]}
  pageType="checkout"
>
  <PayPalGuestPaymentButton
    createOrder={async () => {

      console.log("Guest payment flow completed", data)
    }
  />
</PayPalProvider>;

PayPalSavePaymentButton

Renders a button for vaulting a payment method without making a purchase.

import { PayPalSavePaymentButton } from "@paypal/react-paypal-js/sdk-v6";

<PayPalSavePaymentButton
  createVaultToken={async () => {
    const response = await fetch("/api/create-vault-token", {
      method: "POST",
    });
    const { vaultSetupToken } = await response.json();
    return { vaultSetupToken };
  }}
  onApprove={({ vaultSetupToken }: OnApproveDataSavePayments) => {
    console.log("Payment method saved:", vaultSetupToken);
  }}
  onCancel={(data: OnCancelDataSavePayments) =>
    console.log("Save payment cancelled", data)
  }
  onError={(data: OnErrorData) => console.error("Save payment error:", data)}
  onComplete={(data: OnCompleteData) =>
    console.log("Save payment flow completed", data)
  }
/>;

PayPalSubscriptionButton

import { PayPalSubscriptionButton } from "@paypal/react-paypal-js/sdk-v6";

<PayPalProvider
  clientId={clientId}
  environment="sandbox"
  components={["paypal-subscriptions"]}
  pageType="checkout"
>
  <PayPalSubscriptionButton
    createSubscription={async () => {
      const response = await fetch("/api/create-subscription", {
        method: "POST",
      });
      const { subscriptionId } = await response.json();
      return { subscriptionId };
    }}
    onApprove={(data: OnApproveDataOneTimePayments) =>

      console.log("Subscription flow completed", data)
    }
  />
</PayPalProvider>;

PayPalCreditOneTimePaymentButton

Renders a PayPal Credit button for one-time payments. The countryCode is automatically populated from eligibility data, so eligibility must be fetched first — via useEligibleMethods() client-side (shown below) or the provider's eligibleMethodsResponse prop server-side.

import {
  PayPalCreditOneTimePaymentButton,
  useEligibleMethods,
} from "@paypal/react-paypal-js/sdk-v6";

function CreditCheckout() {
  // Fetch eligibility first (or hydrate server-side via eligibleMethodsResponse)
  const { eligiblePaymentMethods, isLoading } = useEligibleMethods({

  }

  return (
    <PayPalCreditOneTimePaymentButton
      createOrder={async () => {
        const response = await fetch("/api/create-order", { method: "POST" });
        const { orderId } = await response.json();
        return { orderId };
      }}
      onApprove={({ orderId }: OnApproveDataOneTimePayments) =>

      }
    />
  );
}

PayPalCreditSavePaymentButton

import {
  PayPalCreditSavePaymentButton,
  useEligibleMethods,
} from "@paypal/react-paypal-js/sdk-v6";

function CreditSaveCheckout() {
  // Fetch eligibility first (or hydrate server-side via eligibleMethodsResponse)
  const { eligiblePaymentMethods, isLoading } = useEligibleMethods({
    payload: { purchase_units: [{ amount: { currency_code: "USD" } }] },
  });

  if (isLoading) {

  return (
    <PayPalCreditSavePaymentButton
      createVaultToken={async () => {
        const response = await fetch("/api/create-vault-token", {
          method: "POST",
        });
        const { vaultSetupToken } = await response.json();
        return { vaultSetupToken };
      }}
      onApprove={(data: OnApproveDataSavePayments) =>

      }
    />
  );
}

ApplePayOneTimePaymentButton

Renders Apple's native <apple-pay-button> web component and manages the full Apple Pay payment flow — including merchant validation, payment authorization, and order confirmation — via the PayPal SDK.

Requirements:

Safari browser (macOS 10.12+ / iOS 10+)
HTTPS connection
Apple Pay configured on the user's device
components={["applepay-payments"]} in PayPalProvider
Apple Pay JS SDK loaded via a script tag in your HTML:

<script
  crossorigin
  src="https://applepay.cdn-apple.com/jsapi/1.latest/apple-pay-sdk.js"
></script>

Integration steps:

Check window.ApplePaySession?.canMakePayments() — only render the button if this returns true. Wrap in try-catch because it throws on non-HTTPS connections.
Call useEligibleMethods() to fetch eligibility and obtain applePayConfig from getDetails("applepay").config.
Pass applePayConfig explicitly to the component — it is a required prop.

import {
  PayPalProvider,
  ApplePayOneTimePaymentButton,
  useEligibleMethods,
} from "@paypal/react-paypal-js/sdk-v6";

async function createOrder() {
  const response = await fetch("/api/paypal/create-order", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      items: [{ id: "item-1", quantity: 1 }],
    }),
  });
  const data = await response.json();
  return { orderId: data.id };
}

async function onApprove(data) {
  // confirmOrder is handled internally by the hook.
  // Capture the order using the ID from the confirmation response.
  const orderId = data.approveApplePayPayment.id;
  const response = await fetch(`/api/paypal/capture/${orderId}`, {
    method: "POST",
  });
  const result = await response.json();
  console.log("Apple Pay payment captured:", result);
}

function ApplePayCheckout() {
  // Step 1: Check if Apple Pay is supported by the browser/device.
  // canMakePayments() throws on non-HTTPS, so wrap in try-catch.
  let canUseApplePay = false;
  try {
    canUseApplePay =
      typeof window !== "undefined" &&
      !!window.ApplePaySession?.canMakePayments();
  } catch {
    // Not available (e.g., non-HTTPS environment)
  }

  // Step 2: Fetch eligibility.
  // Note: hooks must be called unconditionally (React rules of hooks).
  // To avoid the eligibility API call on unsupported browsers, split the
  // check and the button into separate components in your app.
  const { eligiblePaymentMethods, isLoading, error } = useEligibleMethods({
    payload: { currencyCode: "USD" },
  });

  if (!canUseApplePay) {
    return <div>Apple Pay is not available in this browser.</div>;
  }
  if (isLoading) {
    return <div>Loading...</div>;
  }
  if (error) {
    return <div>Error: {error.message}</div>;
  }

  // Step 3: Check merchant eligibility and get config.
  const isEligible = eligiblePaymentMethods?.isEligible("applepay");
  if (!isEligible) {
    return <div>Apple Pay is not eligible.</div>;
  }

  const applePayConfig = eligiblePaymentMethods?.getDetails("applepay")?.config;
  if (!applePayConfig) {
    return null;
  }

  return (
    <ApplePayOneTimePaymentButton
      applePayConfig={applePayConfig}
      paymentRequest={{
        countryCode: "US",
        currencyCode: "USD",

        ],
        requiredShippingContactFields: [],
        total: {
          label: "Demo (Card is not charged)",
          amount: "20.00",
          type: "final",

      type="buy"
    />
  );
}

export default function App() {

      components={["applepay-payments"]}
      pageType="checkout"

Key differences from other PayPal buttons:

No presentationMode — Apple controls the native payment sheet UI
No eager order creation (orderId prop) — orders are always created lazily during payment authorization
applePayConfig is required and must be obtained from useEligibleMethods()
onApprove receives ConfirmOrderResponse — capture the order using data.approveApplePayPayment.id

Braintree PayPal Integration

Braintree merchants use BraintreePayPalProvider instead of PayPalProvider to integrate PayPal via Braintree's paypalCheckoutV6 module. This provider initializes the Braintree client, creates a PayPal Checkout V6 instance, and loads the PayPal SDK — then exposes the instance to child components and hooks via React context.

Resources:

Braintree PayPalCheckoutV6 API Reference — full method signatures, options, and type definitions
Sample Integration Repo — working Braintree + React example with setup instructions
Braintree Server SDK Guide — server-side nonce processing

Prerequisites

A Braintree merchant account with PayPal enabled
A Braintree client token generated server-side via the Braintree SDK. See the sample integration's gateway setup and client token route handler for a Node.js example.
The Braintree Web client and paypal-checkout-v6 scripts loaded before rendering:

<script src="https://js.braintreegateway.com/web/3.142.0/js/client.min.js"></script>
<script src="https://js.braintreegateway.com/web/3.142.0/js/paypal-checkout-v6.min.js"></script>

BraintreePayPalProvider

Wraps child components with Braintree context. On mount it validates the namespace, creates a Braintree client instance, creates a paypalCheckoutV6 instance, and calls loadPayPalSDK(). On unmount it calls teardown() to release resources.

import { useState, useEffect } from "react";
import { BraintreePayPalProvider } from "@paypal/react-paypal-js/sdk-v6";

declare global {
  interface Window {
    braintree: BraintreeV6Namespace;
  }
}

function App() {
  const [clientToken, setClientToken] = useState<string | undefined>(undefined);

  useEffect(() => {
    fetch("/auth/browser-safe-client-token")
      .then((res) => res.json())
      .then(({ clientToken }) => setClientToken(clientToken));
  }, []);

  if (!clientToken) {
    return <div>Loading...</div>;
  }

  return (
    <BraintreePayPalProvider
      namespace={window.braintree}
      braintreeClientToken={clientToken}
    >
      <CheckoutPage />
    </BraintreePayPalProvider>
  );
}

Props:

Prop	Type	Required	Description
`namespace`	`BraintreeV6Namespace`	Yes	The `braintree` global namespace — must expose `client.create` and `paypalCheckoutV6.create` functions
`braintreeClientToken`	`string \| undefined`	Yes	Client token from your server (generated via the Braintree SDK)
`children`	`ReactNode`	Yes	Child components

Note: The namespace prop must have referential stability across renders. An unstable reference (e.g., creating the object inline) will cause re-initialization on every render. Use a module-level constant, useRef, or useMemo.

BraintreePayPalOneTimePaymentButton

Renders a <paypal-button> web component for one-time Braintree PayPal payments. Internally uses useBraintreePayPalOneTimePaymentSession to create and start payment sessions.

import {
  BraintreePayPalProvider,
  BraintreePayPalOneTimePaymentButton,
  useBraintreePayPal,
} from "@paypal/react-paypal-js/sdk-v6";
import type { BraintreeApprovalData } from "@paypal/react-paypal-js/sdk-v6";

function CheckoutPage() {
  const { braintreePayPalCheckoutInstance } = useBraintreePayPal();

  return (
    <BraintreePayPalOneTimePaymentButton
      amount="100.00"
      currency="USD"
      intent="capture"
      type="pay"
      onApprove={async (data: BraintreeApprovalData) => {
        const { nonce } =
          await braintreePayPalCheckoutInstance!.tokenizePayment(data);
        // Send nonce to your server
        await fetch("/api/braintree/checkout", {
          method: "POST",
          headers: { "Content-Type": "application/json" },
          body: JSON.stringify({ nonce }),
        });
      }}
      onCancel={(data) => console.log("Cancelled", data)}
      onError={(err) => console.error("Error", err)}
    />
  );
}

function App() {
  const [clientToken, setClientToken] = useState<string | undefined>(undefined);

  useEffect(() => {
    fetch("/auth/browser-safe-client-token")
      .then((res) => res.json())
      .then(({ clientToken }) => setClientToken(clientToken));
  }, []);

  if (!clientToken) {
    return <div>Loading...</div>;
  }

  return (
    <BraintreePayPalProvider
      namespace={window.braintree}
      braintreeClientToken={clientToken}
    >
      <CheckoutPage />
    </BraintreePayPalProvider>

BraintreePayPalPayLaterButton

Renders a <paypal-pay-later-button> web component for Braintree PayPal Pay Later (Buy Now, Pay Later) financing. Internally uses useBraintreePayPalPayLaterSession to create and start Pay Later sessions.

Unlike the other Braintree buttons, this button requires eligibility data. It reads countryCode and productCode from useBraintreePayPal().eligiblePaymentMethods, which is populated by useBraintreeEligibleMethods. Fetch eligibility first — without it the button renders hidden (display: none).

import {
  BraintreePayPalPayLaterButton,
  useBraintreePayPal,
  useBraintreeEligibleMethods,
  INSTANCE_LOADING_STATE,
} from "@paypal/react-paypal-js/sdk-v6";
import type { BraintreeApprovalData } from "@paypal/react-paypal-js/sdk-v6";

function PayLaterCheckout() {
  const { loadingStatus, braintreePayPalCheckoutInstance } =
    useBraintreePayPal();

  // Fetch eligibility before rendering the button
  const { eligiblePaymentMethods, isLoading } = useBraintreeEligibleMethods({
    amount: "100.00",
    currency: "USD", // required
    countryCode: "US",
    paymentFlow: "ONE_TIME_PAYMENT",
  });

  if (isLoading || loadingStatus === INSTANCE_LOADING_STATE.PENDING) {
    return <Spinner />;
  }
  if (!eligiblePaymentMethods?.paylater) {
    return null;
  }

  return (
    <BraintreePayPalPayLaterButton
      amount="100.00"
      currency="USD"
      onApprove={async (data: BraintreeApprovalData) => {
        const { nonce } =
          await braintreePayPalCheckoutInstance!.tokenizePayment(data);
        // Send nonce to your server
        await fetch("/api/braintree/checkout", {
          method: "POST",
          headers: { "Content-Type": "application/json" },
          body: JSON.stringify({ nonce }),
        });
      }}
      onCancel={() => console.log("Cancelled")}
      onError={(err) => console.error("Error", err)}
    />
  );

Braintree Hooks

`useBraintreePayPal()`

Accesses the Braintree PayPal context. Returns the checkout instance, loading status, and error state. Must be used within a BraintreePayPalProvider.

import {
  useBraintreePayPal,
  INSTANCE_LOADING_STATE,
} from "@paypal/react-paypal-js/sdk-v6";

function CustomCheckout() {
  const { braintreePayPalCheckoutInstance, loadingStatus, error, isHydrated } =
    useBraintreePayPal();

  if (loadingStatus === INSTANCE_LOADING_STATE.PENDING) {
    return <div>Initializing Braintree...</div>;
  }

  if (error) {
    return <div>Error: {error.message}</div>;
  }

  // Use braintreePayPalCheckoutInstance directly for custom flows
}

Returns:

Property	Type	Description
`braintreePayPalCheckoutInstance`	`BraintreePayPalCheckoutInstance \| null`	The checkout instance (null while loading)
`eligiblePaymentMethods`	`BraintreeEligibilityResult \| null`	Eligibility cached by `useBraintreeEligibleMethods` (`null` until fetched)
`loadingStatus`	`INSTANCE_LOADING_STATE`	`"pending"`, `"resolved"`, or `"rejected"`
`error`	`Error \| null`	Initialization error, if any
`isHydrated`	`boolean`	`true` after client-side hydration

`useBraintreeEligibleMethods(props)`

Fetches Braintree PayPal eligibility for the given checkout options by calling findEligibleMethods() on the shared checkout instance, and caches the result in BraintreePayPalProvider context (where buttons read it via useBraintreePayPal().eligiblePaymentMethods). Fetches are deduplicated by (instance, options) and re-run when the options change. Required before rendering eligibility-gated buttons such as BraintreePayPalPayLaterButton.

import {
  useBraintreePayPal,
  useBraintreeEligibleMethods,
  BraintreePayPalOneTimePaymentButton,
  BraintreePayPalPayLaterButton,
  INSTANCE_LOADING_STATE,
} from "@paypal/react-paypal-js/sdk-v6";

function CheckoutButtons() {
  const { loadingStatus, braintreePayPalCheckoutInstance } =
    useBraintreePayPal();
  const { eligiblePaymentMethods, isLoading, error } =
    useBraintreeEligibleMethods({
      amount: "100.00",
      currency: "USD",
      countryCode: "US",
      paymentFlow: "ONE_TIME_PAYMENT",
    });

  if (isLoading || loadingStatus === INSTANCE_LOADING_STATE.PENDING) {
    return <Spinner />;
  }
  if (error) {
    return <div>Error: {error.message}</div>;
  }

  return (
    <>
      <BraintreePayPalOneTimePaymentButton
        amount="100.00"
        currency="USD"
        // onApprove not shown in this example
        // see other examples for usage of tokenizePayment in onApprove
        onApprove={onApprove}
      />
      {eligiblePaymentMethods?.paylater && (
        <BraintreePayPalPayLaterButton
          amount="100.00"
          currency="USD"
          onApprove={onApprove}
        />
      )}
    </>
  );
}

Prop	Type	Required	Description
`currency`	`string`	Yes	ISO 4217 currency code (e.g., `"USD"`)
`amount`	`string`	No	Checkout amount used for eligibility checks
`countryCode`	`string`	No	Buyer country code (e.g., `"US"`)

Creates a one-time payment session. Returns a handleClick function to start the PayPal flow. Accepts the same props as BraintreePayPalOneTimePaymentButton (minus type and disabled).

import { useBraintreePayPalOneTimePaymentSession } from "@paypal/react-paypal-js/sdk-v6";

function CustomPayButton() {
  const { handleClick, isPending, error } =
    useBraintreePayPalOneTimePaymentSession({
      amount: "50.00",
      currency: "USD",

    </button>
  );
}

      Save PayPal Account
    </button>
  );
}

Returns: { handleClick: () => void, isPending: boolean, error: Error | null }

`useBraintreePayPalCheckoutWithVaultSession(props)`

`useBraintreePayPalPayLaterSession(props)`

Creates a Pay Later (Buy Now, Pay Later) session. Returns a handleClick function to start the flow. Accepts the same props as BraintreePayPalPayLaterButton (minus disabled) — use this hook directly when you need full control over the <paypal-pay-later-button> UI. Eligibility (countryCode/productCode) must still be fetched via useBraintreeEligibleMethods.

import {
  useBraintreePayPalPayLaterSession,
  useBraintreeEligibleMethods,
} from "@paypal/react-paypal-js/sdk-v6";

function CustomPayLaterButton() {
  const { handleClick, isPending } = useBraintreePayPalPayLaterSession({
    amount: "100.00",
    currency: "USD",
    onApprove: async (data) => {
      // tokenize and process
    },

    return <Spinner />;
  }
  if (!eligiblePaymentMethods?.paylater) {
    return null;
  }

  const payLaterDetails = eligiblePaymentMethods.getDetails("paylater");

      onClick={() => handleClick()}
      disabled={isPending}
      countryCode={payLaterDetails?.countryCode}
      productCode={payLaterDetails?.productCode}
    />
  );
}

Returns: { handleClick: () => void, isPending: boolean, error: Error | null }

  BraintreeTokenizePayload,
  BraintreeLineItem,
  BraintreeShippingOption,
  BraintreeAmountBreakdown,
  BraintreePlanMetadata,
  BraintreePresentationMode,
  BraintreeV6Namespace,
} from "@paypal/react-paypal-js/sdk-v6";

Type	Description
`BraintreeApprovalData`	`{ payerId?, orderId?, billingToken? }` — data passed to `onApprove`
`BraintreeTokenizePayload`	`{ nonce, type, details: { email, payerId, firstName, lastName, ... } }` — result of `tokenizePayment`

Key Differences from Standard PayPal Buttons

Different provider — uses BraintreePayPalProvider with a Braintree client token instead of PayPalProvider with a PayPal client ID
No createOrder / orderId — payment sessions are created internally by the Braintree SDK; you pass amount and currency directly as props
Nonce-based flow — onApprove receives BraintreeApprovalData; call braintreePayPalCheckoutInstance.tokenizePayment() to get a payment method nonce
Server-side with Braintree SDK — send the nonce to your server and process it with the Braintree server SDK (not PayPal's Orders API)
Presentation modes — supports "auto", "popup", "modal", "redirect", "payment-handler", and "direct-app-switch"

Payment Flow

User clicks a payment button
handleClick() starts the payment session
createOrder callback creates an order via your backend API
PayPal opens the checkout experience (popup/modal/redirect)
On approval, onApprove callback captures the order via the backend
Success/error handling displays the result to the user

Card Fields Components

Card Fields components provide customizable card input fields for collecting payment details directly on your page.

Requires "card-fields" in the provider's components array.

PayPalCardFieldsProvider

Wraps card field components and manages the Card Fields session.

import {
  PayPalProvider,
  PayPalCardFieldsProvider,
} from "@paypal/react-paypal-js/sdk-v6";

function App() {
  return (
    <PayPalProvider
      clientToken="your-client-token"
      environment="sandbox"
      components={["card-fields"]}
      pageType="checkout"
    >
      <CheckoutForm />
    </PayPalProvider>
  );
}

function CheckoutForm() {
  return (
    <PayPalCardFieldsProvider>
      <CardPaymentForm />
    </PayPalCardFieldsProvider>
  );
}

Props:

Prop	Type	Required	Description
`amount`	`OrderAmount`	No	Amount for the card transaction (e.g., `{ value: "10.00", currencyCode: "USD" }`)
`isCobrandedEligible`	`boolean`	No	Enable co-branded card eligibility
`blur`	`(event) => void`	No	Callback when a field loses focus
`change`	`(event) => void`	No	Callback when field value changes
`focus`	`(event) => void`	No	Callback when field receives focus
`empty`	`(event) => void`	No	Callback when field becomes empty
`notempty`	`(event) => void`	No	Callback when field becomes non-empty
`validitychange`	`(event) => void`	No	Callback when field validity changes
`cardtypechange`	`(event) => void`	No	Callback when detected card type changes
`inputsubmit`	`(event) => void`	No	Callback when submit key is pressed in field

PayPalCardNumberField

Renders a card number input field. Must be used within a PayPalCardFieldsProvider component.

import { PayPalCardNumberField } from "@paypal/react-paypal-js/sdk-v6";

<PayPalCardNumberField
  placeholder="Card number"
  containerStyles={{ height: "3rem", marginBottom: "1rem" }}
/>;

PayPalCardExpiryField

Renders a card expiry input field. Must be used within a PayPalCardFieldsProvider component.

import { PayPalCardExpiryField } from "@paypal/react-paypal-js/sdk-v6";

<PayPalCardExpiryField
  placeholder="MM/YY"
  containerStyles={{ height: "3rem", marginBottom: "1rem" }}
/>;

PayPalCardCvvField

Renders a CVV input field. Must be used within a PayPalCardFieldsProvider component.

import { PayPalCardCvvField } from "@paypal/react-paypal-js/sdk-v6";

<PayPalCardCvvField
  placeholder="CVV"
  containerStyles={{ height: "3rem", marginBottom: "1rem" }}
/>;

Field Component Props

All field components (PayPalCardNumberField, PayPalCardExpiryField, PayPalCardCvvField) accept the same set of props. They combine container styling properties with CardField-specific configuration options.

Prop	Type	Required	Description
`placeholder`	`string`	No	Placeholder text for the field
`label`	`string`	No	Label text for the field
`style`	`MerchantStyleObject`	No	Style object for the field
`ariaLabel`	`string`	No	ARIA label for accessibility
`ariaDescription`	`string`	No	ARIA description for accessibility
`ariaInvalidErrorMessage`	`string`	No	ARIA error message when field is invalid
`containerStyles`	`React.CSSProperties`	No	CSS styles for the field container wrapper
`containerClassName`	`string`	No	CSS class name for the field container wrapper

Payment Flow: Card Fields

User enters card number, expiry, and CVV in the card fields
User clicks your submit button
createOrder creates an order via your backend API
submit(orderId) processes the card payment with the order ID
submitResponse object gets updated with the payment result
Handle submit response based on payment result

Hooks API

usePayPal

Returns the PayPal context including the SDK instance and loading status.

import {
  usePayPal,
  INSTANCE_LOADING_STATE,
} from "@paypal/react-paypal-js/sdk-v6";

function MyComponent() {
  const {
    sdkInstance, // The PayPal SDK instance
    eligiblePaymentMethods, // Eligible payment methods
    loadingStatus, // PENDING | RESOLVED | REJECTED
    error, // Any initialization error
    isHydrated, // SSR hydration status
  } = usePayPal();

  const isPending = loadingStatus === INSTANCE_LOADING_STATE.PENDING;
  const isReady = loadingStatus === INSTANCE_LOADING_STATE.RESOLVED;

  // ...
}

useEligibleMethods

Returns eligible payment methods and loading state. Use this to conditionally render payment buttons based on eligibility. This hook also updates the PayPalProvider reducer with Eligibility Output from the SDK, enabling built-in eligibility features in the UI Button components.

import { useEligibleMethods } from "@paypal/react-paypal-js/sdk-v6";

function PaymentOptions() {
  const { eligiblePaymentMethods, isLoading, error } = useEligibleMethods();

  if (isLoading) {
    return <div>Checking eligibility...</div>;
  }

  const isPayPalEligible = eligiblePaymentMethods?.isEligible("paypal");
  const isVenmoEligible = eligiblePaymentMethods?.isEligible("venmo");
  const isPayLaterEligible = eligiblePaymentMethods?.isEligible("paylater");

  return (
    <div>
      {isPayPalEligible && <PayPalOneTimePaymentButton {...props} />}
      {isVenmoEligible && <VenmoOneTimePaymentButton {...props} />}
      {isPayLaterEligible && <PayLaterOneTimePaymentButton {...props} />}
    </div>
  );
}

Stale Eligibility Data Prevention

When navigating between different payment flows (e.g., from a save payment page with paymentFlow: "VAULT_WITHOUT_PAYMENT" to a checkout page with paymentFlow: "ONE_TIME_PAYMENT"), isLoading will return true while the new eligibility data is being fetched. This prevents stale buttons from flashing before the updated eligibility response arrives.

If your app uses a single PayPalProvider across multiple routes with different paymentFlow values, always check isLoading before rendering eligibility-dependent buttons:

const { eligiblePaymentMethods, isLoading } = useEligibleMethods({
  payload: { currencyCode: "USD", paymentFlow: "ONE_TIME_PAYMENT" },
});

// Guard eligibility-dependent buttons with isLoading to avoid rendering
// buttons based on stale data from a previous payment flow
const isPayLaterEligible =
  !isLoading && eligiblePaymentMethods?.isEligible("paylater");

usePayPalMessages

Hook for integrating PayPal messaging (Pay Later promotions).

import { usePayPalMessages } from "@paypal/react-paypal-js/sdk-v6";

function PayLaterMessage() {
  const { error, isReady, handleFetchContent, handleCreateLearnMore } =
    usePayPalMessages({
      buyerCountry: "US",
      currencyCode: "USD",
    });

  // Use to display financing messages
}

usePayPalCardFields

Returns the Card Fields instance initialization errors. Must be used within a PayPalCardFieldsProvider component.

import { usePayPalCardFields } from "@paypal/react-paypal-js/sdk-v6";

function CardFields() {
  const { error } = usePayPalCardFields();

  useEffect(() => {
    if (error) {
      // Handle error logic
      console.error("Error initializing PayPal Card Fields: ", error);
    }
  }, [error]);

  return <CardPaymentForm />;
}

Payment Session Hooks

For advanced use cases where you need full control over the payment flow, use the session hooks directly with web components.

Note: One-time payment session hooks (e.g., usePayPalOneTimePaymentSession) accept either a static orderId or a createOrder callback — they are mutually exclusive. Use orderId when you've already created the order, or createOrder to defer order creation until the buyer clicks. The same pattern applies to save payment hooks with vaultSetupToken vs createVaultToken.

Hook	Payment Type
`usePayPalOneTimePaymentSession`	PayPal
`useVenmoOneTimePaymentSession`	Venmo
`usePayLaterOneTimePaymentSession`	Pay Later
`usePayPalGuestPaymentSession`	Basic Card
`usePayPalSubscriptionPaymentSession`	Subscriptions
`usePayPalSavePaymentSession`	Save Payment Method
`usePayPalCreditOneTimePaymentSession`	Credit (One-time)
`usePayPalCreditSavePaymentSession`	Credit (Save)
`useGooglePayOneTimePaymentSession`	Google Pay
`useApplePayOneTimePaymentSession`	Apple Pay

Use these hooks to handle the Card Fields payment flows. The hooks must be used within a PayPalCardFieldsProvider component.

Hook	Payment Type
`usePayPalCardFieldsOneTimePaymentSession`	One-time
`usePayPalCardFieldsSavePaymentSession`	Save/Vault

usePayPalCardFieldsOneTimePaymentSession

Hook for managing one-time payment Card Fields sessions.

      return;
    }

    const { orderId, message } = submitResponse.data;

    switch (submitResponse.state) {
      case "succeeded":
        // Handle submit success logic
        console.log(`One time payment succeeded: orderId: ${orderId}`);
        break;
      case "failed":
        // Handle submit failed response logic
        console.error(
          `One time payment failed: orderId: ${orderId}, message: ${message}`,
        );
        break;
    }
  }, [submitResponse]);

  const handleSubmit = async () => {
    const orderId = await createOrder();
    await submit(orderId);
  };

  return (
    <div>
      <PayPalCardNumberField />
      <PayPalCardExpiryField />
      <PayPalCardCvvField />
      <button onClick={handleSubmit}>Pay</button>
    </div>
  );
}

usePayPalCardFieldsSavePaymentSession

Hook for managing save payment Card Fields sessions.

import { usePayPalCardFieldsSavePaymentSession } from "@paypal/react-paypal-js/sdk-v6";

function CardPaymentForm() {
  const { submit, submitResponse, error } =
    usePayPalCardFieldsSavePaymentSession();

  useEffect(() => {
    if (error) {
      // Handle submit error logic
      console.error(
        "Error submitting PayPal Card Fields payment method",
        error,
      );
    }
  }, [error]);

  useEffect(() => {
    if (!submitResponse) {
      return;
    }

    const { vaultSetupToken, message } = submitResponse.data;

    switch (submitResponse.state) {
      case "succeeded":
        // Handle submit success logic
        console.log(
          `Save payment method succeeded: vaultSetupToken: ${vaultSetupToken}`,
        );
        break;
      case "failed":
        // Handle submit failed response logic
        console.error(
          `Save payment method failed: vaultSetupToken: ${vaultSetupToken}, message: ${message}`,
        );
        break;
    }
  }, [submitResponse]);

    const { vaultSetupToken } = await createCardVaultToken();
    await submit(vaultSetupToken);
  };

  return (
    <div>
      <PayPalCardNumberField />
      <PayPalCardExpiryField />
      <PayPalCardCvvField />
      <button onClick={handleSubmit}>Save Payment Method</button>
    </div>
  );
}

Web Components

The V6 SDK uses web components for rendering buttons. These are automatically typed when you import from @paypal/react-paypal-js/sdk-v6.

Available Web Components

Component	Description
`<paypal-button>`	PayPal payment button
`<venmo-button>`	Venmo payment button
`<paypal-pay-later-button>`	Pay Later button
`<paypal-basic-card-container>`	Guest checkout container
`<paypal-basic-card-button>`	Guest checkout button
`<paypal-credit-button>`	PayPal Credit button
`<paypal-message>`	PayPal messaging component

Button Types

The type prop controls the button label:

"pay" - "Pay with PayPal" (default)
"checkout" - "Checkout with PayPal"
"buynow" - "Buy Now"
"donate" - "Donate"
"subscribe" - "Subscribe"

<paypal-button type="checkout" onClick={handleClick} />

Server-Side Rendering

The useFetchEligibleMethods function is available from the server export path for pre-fetching eligibility data on the server. Pass the response to PayPalProvider via the eligibleMethodsResponse prop to avoid a client-side eligibility fetch.

// app/checkout/page.tsx (Next.js server component)
import { useFetchEligibleMethods } from "@paypal/react-paypal-js/sdk-v6/server";
import { PayPalProvider } from "@paypal/react-paypal-js/sdk-v6";

export default async function CheckoutPage() {
  const eligibleMethodsResponse = await useFetchEligibleMethods({
    environment: "sandbox",
    headers: {
      Authorization: `Bearer ${clientToken}`,
      "Content-Type": "application/json",
    },
    payload: {
      purchase_units: [{ amount: { currency_code: "USD", value: "100.00" } }],
    },
  });

  return (
    <PayPalProvider
      clientId={clientId}
      environment="sandbox"
      pageType="checkout"
      eligibleMethodsResponse={eligibleMethodsResponse}
    >
      <CheckoutForm />
    </PayPalProvider>
  );
}

Migration from v8.x (Legacy SDK)

The v9.0.0 release introduces the V6 SDK with a new API. Here are the key differences:

v8.x (Legacy)	v9.0.0 (V6 SDK)
`PayPalScriptProvider`	`PayPalProvider`
`PayPalButtons`	`PayPalOneTimePaymentButton` or hooks
`options={{ clientId }}`	`clientId={clientId}` or `clientToken={clientToken}`
`createOrder` returns `orderId`	`createOrder` returns `{ orderId }`
`@paypal/react-paypal-js`	`@paypal/react-paypal-js/sdk-v6`

Before (v8.x)

import { PayPalScriptProvider, PayPalButtons } from "@paypal/react-paypal-js";

<PayPalScriptProvider options={{ clientId: "test" }}>
  <PayPalButtons
    createOrder={() => {
      return fetch("/api/orders", { method: "POST" })
        .then((res) => res.json())
        .then((order) => order.id);
    }}
    onApprove={(data) => {
      return fetch(`/api/orders/${data.orderID}/capture`, {
        method: "POST",
      });
    }}
  />
</PayPalScriptProvider>;

After (v9.0.0)

import {
  PayPalProvider,
  PayPalOneTimePaymentButton,
} from "@paypal/react-paypal-js/sdk-v6";

<PayPalProvider clientId={clientId} environment="sandbox" pageType="checkout">
  <PayPalOneTimePaymentButton
    createOrder={async () => {
      const res = await fetch("/api/orders", { method: "POST" });
      const order = await res.json();
      return { orderId: order.id };
    }}
    onApprove={async ({ orderId }) => {
      await fetch(`/api/orders/${orderId}/capture`, { method: "POST" });
    }}
  />
</PayPalProvider>;

For the legacy API documentation, see README-v8.md.
