PayPalCheckout

PayPalCheckout

This class represents a PayPal Checkout component that coordinates with the PayPal SDK. Instances of this class can generate payment data and tokenize authorized payments.

All UI (such as preventing actions on the parent page while authentication is in progress) is managed by the PayPal SDK. You must provide your PayPal client-id as a query parameter. You can retrieve this value from the PayPal Dashboard.

Constructor

new PayPalCheckout(options)

Do not use this constructor directly. Use braintree-web.paypal-checkout.create instead.

Integrate Checkout Flow with PayPal SDK

You must have PayPal's script, configured with various query parameters, loaded on your page:

<script src="https://www.paypal.com/sdk/js?client-id=your-sandbox-or-prod-client-id"></script>
<div id="paypal-button"></div>

When passing values in the createPayment method, make sure they match the corresponding parameters in the query parameters for the PayPal SDK script.

braintree.client.create({
  authorization: 'authorization'
}).then(function (clientInstance) {
  return braintree.paypalCheckout.create({
    client: clientInstance
  });
}).then(function (paypalCheckoutInstance) {
  return paypal.Buttons({
    createOrder: function () {
      return paypalCheckoutInstance.createPayment({
        flow: 'checkout',
        currency: 'USD',
        amount: '10.00',
        intent: 'capture' // this value must either be `capture` or match the intent passed into the PayPal SDK intent query parameter
        // your other createPayment options here
      });
    },

    onApprove: function (data, actions) {
      // some logic here before tokenization happens below
      return paypalCheckoutInstance.tokenizePayment(data).then(function (payload) {
        // Submit payload.nonce to your server
      });
    },

    onCancel: function () {
      // handle case where user cancels
    },

    onError: function (err) {
      // handle case where error occurs
    }
  }).render('#paypal-button');
}).catch(function (err) {
 console.error('Error!', err);
});

Integrate Vault Flow with PayPal SDK

You must have PayPal's script, configured with various query parameters, loaded on your page:

<script src="https://www.paypal.com/sdk/js?client-id=your-sandbox-or-prod-client-id&vault=true"></script>
<div id="paypal-button"></div>

When passing values in the createPayment method, make sure they match the corresponding parameters in the query parameters for the PayPal SDK script.

braintree.client.create({
  authorization: 'authorization'
}).then(function (clientInstance) {
  return braintree.paypalCheckout.create({
    client: clientInstance
  });
}).then(function (paypalCheckoutInstance) {
  return paypal.Buttons({
    createBillingAgreement: function () {
      return paypalCheckoutInstance.createPayment({
        flow: 'vault'
        // your other createPayment options here
      });
    },

    onApprove: function (data, actions) {
      // some logic here before tokenization happens below
      return paypalCheckoutInstance.tokenizePayment(data).then(function (payload) {
        // Submit payload.nonce to your server
      });
    },

    onCancel: function () {
      // handle case where user cancels
    },

    onError: function (err) {
      // handle case where error occurs
    }
  }).render('#paypal-button');
}).catch(function (err) {
 console.error('Error!', err);
});

Integrate with Checkout.js (deprecated PayPal SDK)

If you are creating a new PayPal integration, please follow the previous integration guide to use the current version of the PayPal SDK. Use this integration guide only as a reference if you are already integrated with Checkout.js.

You must have PayPal's Checkout.js script loaded on your page.

<script src="https://www.paypalobjects.com/api/checkout.js" data-version-4 log-level="warn"></script>
braintree.client.create({
  authorization: 'authorization'
}).then(function (clientInstance) {
  return braintree.paypalCheckout.create({
    client: clientInstance
  });
}).then(function (paypalCheckoutInstance) {
  return paypal.Button.render({
    env: 'production', // or 'sandbox'

    payment: function () {
      return paypalCheckoutInstance.createPayment({
        // your createPayment options here
      });
    },

    onAuthorize: function (data, actions) {
      // some logic here before tokenization happens below
      return paypalCheckoutInstance.tokenizePayment(data).then(function (payload) {
        // Submit payload.nonce to your server
      });
    }
  }, '#paypal-button');
}).catch(function (err) {
 console.error('Error!', err);
});
