Set up your sandbox account to accept Google Pay

Before you can accept Google Pay on your website, verify that your sandbox business account supports Google Pay.

Partners can use the PayPal Developer Dashboard to set up their sandbox accounts to accept Google Pay. The integration for partner accounts includes creating a sandbox business account through sandbox.paypal.com. If the Google Pay status for the account shows as disabled, complete the sandbox onboarding steps to enable Google Pay.

  1. Log into the PayPal Developer Dashboard and go to your sandbox account.
  2. Go to Apps & Credentials.
  3. Make sure you are in the PayPal sandbox environment by selecting Sandbox at the top.
  4. Select or create an app.
  5. Scroll down to Mobile and digital payments and check if Google Pay is enabled. If Google Pay isn't enabled, select the Google Pay checkbox.

If you created a sandbox business account through sandbox.paypal.com, and the Google Pay status for the account shows as disabled, complete the sandbox onboarding steps to enable Google Pay.

Getting started in your testing environment

Before you develop your Google Pay on the Web integration, you need to complete Get started to set up your PayPal account, client ID, and sandbox emails for testing.

3

Integrate Google Pay checkout

Follow this integration process to add Google Pay as a checkout option, customize the payment experience, and process payments.

Call the Orders API

To accept Google Pay directly on your website, create API endpoints on your server that communicate with the PayPal Orders V2 API. These endpoints can create an order, authorize payment, and capture payment for an order.

Server-side example (Node.js)

This code demonstrates using the PayPal Orders V2 API to add routes to an Express server for creating orders and capturing payments.

Find the complete sample code in the GitHub repo.

  1. server.js
  2. paypal-api.js
1import * as PayPal from "./paypal-api.js";
2/* Create Order route Handler */
3app.post("/api/orders", async (req, res) => {
4 const order = await PayPal.createOrder();
5 res.json(order);
6});
7/* Capture Order route Handler */
8app.post("/api/orders/:orderID/capture", async (req, res) => {
9 const {
10 orderID
11 } = req.params;
12 const captureData = await PayPal.capturePayment(orderID);
13 res.json(captureData);
14});

Set up your Google Pay button

You need to integrate with the Google Pay JavaScript SDK and PayPal JavaScript SDK to add Google Pay to your site.

Integrate PayPal JavaScript SDK

Use this script to integrate with the PayPal JavaScript SDK:

    1<script src="https://www.paypal.com/sdk/js?client-id=YOUR_CLIENT_ID¤cy=USD&buyer-country=US&merchant-id=SUB_MERCHANT_ID&components=googlepay"></script>

    Include googlepay in the components list.

    Integrate Google JavaScript SDK

    Use this script to integrate with the Google Pay JavaScript SDK:

      1<script async src="https://pay.google.com/gp/p/js/pay.js" onload="onGooglePayLoaded()"></script>

      PayPal’s Google Pay component interacts with your JavaScript code in 2 areas:

      1. Checking merchant eligibility and providing PaymentDataRequest parameters for Google Pay: paypal.Googlepay().config().
      2. Handling the onPaymentAuthorized() callback: paypal.Googlepay().confirmOrder().

      Check for device and merchant eligibility before setting up the GooglePay Button.

      The PayPal JavaScript SDK API paypal.Googlepay().config() response object provides the allowedPaymentMethods parameter, which is part of the" "} Google API's isReadyToPayRequest object.

      Check whether the Google Pay API supports a device, browser, and payment method:

      • Add allowedPaymentMethods to the isReadyToPayRequest.
      • Call the isReadyToPay() method to check compatibility and render the Google Pay Button.
        1/**
        2 * Initialize Google PaymentsClient after Google-hosted JavaScript has loaded
        3 *
        4 * Display a Google Pay payment button after confirmation of the viewer's
        5 * ability to pay.
        6 */
        7function onGooglePayLoaded() {
        8 const paymentsClient = getGooglePaymentsClient();
        9 paymentsClient.isReadyToPay(isReadyToPayRequest).then(function(response) {
        10 if (response.result) {
        11 addGooglePayButton();
        12 }
        13 }).catch(function(err) {
        14 console.error(err);
        15 });
        16}
        17/**
        18 * Add a Google Pay purchase button
        19 */
        20function addGooglePayButton() {
        21 const paymentsClient = getGooglePaymentsClient();
        22 const button = paymentsClient.createButton({
        23 onClick: onGooglePaymentButtonClicked /* To be defined later */,
        24 allowedPaymentMethods: [baseCardPaymentMethod]
        25 });
        26 document.getElementById('container').appendChild(button);
        27}
        5

        Create PaymentDataRequest

        The PaymentDataRequest object manages the Google Pay payment process on the web. Create a new PaymentDataRequest each time a payer explicitly requests a payment, such as inside the onclick handler for the Google Pay Button.

        For each checkout session, create a `PaymentDataRequest` object, which includes information about payment processing capabilities, the payment amount, and shipping information.

        The response object of the PayPal JavaScript SDK API paypal.Googlepay().config() provides the following parameters in the PaymentDataRequest object:

        • allowedPaymentMethods
        • merchantInfo
          1/* Note: the `googlePayConfig` object in this request is the response from `paypal.Googlepay().config()` */
          2asyncfunctiongetGooglePaymentDataRequest(){
          3const googlePayConfig =await paypal.Googlepay().config();
          4const paymentDataRequest =Object.assign({}, baseRequest);
          5 paymentDataRequest.allowedPaymentMethods= googlePayConfig.allowedPaymentMethods;
          6// Uncomment for Japan integrations only
          7// paymentDataRequest.allowedPaymentMethods[0].parameters.allowedAuthMethods = ['PAN_ONLY'];
          8 paymentDataRequest.transactionInfo=getGoogleTransactionInfo();
          9 paymentDataRequest.merchantInfo= googlePayConfig.merchantInfo;
          10 paymentDataRequest.callbackIntents=["PAYMENT_AUTHORIZATION"];
          11return paymentDataRequest;
          12}
          13functiongetGoogleTransactionInfo(){
          14return{
          15currencyCode:'USD',
          16totalPriceStatus:'FINAL',
          17totalPrice:'100.00'// Your amount
          18}
          19}

          For more details about the response parameters, see the ConfigResponse section.

          For more details about how Google Pay handles paymentDataRequest, refer to steps 8, 9, and 10 in Google's developer documentation.

          Register click handler

          Register a click event handler for the Google Pay purchase button. Call loadPaymentData() in the event handler when the user interacts with the purchase button and pass the PaymentDataRequest object.

            1/**
            2 * Show Google Pay payment sheet when Google Pay payment button is clicked
            3 */
            4asyncfunctiononGooglePaymentButtonClicked(){
            5const paymentDataRequest =awaitgetGooglePaymentDataRequest();
            6const paymentsClient =getGooglePaymentsClient();
            7 paymentsClient.loadPaymentData(paymentDataRequest);
            8}

            Add the click handler onGooglePaymentButtonClicked to the Button defined in Set up your Google Pay button.

            For more details about paymentDataRequest refer to step 9 in Google's developer documentation.

            onpaymentauthorized callback

            Google calls the onPaymentAuthorized() callback with a PaymentData object when a customer consents to your site collecting their payment information and optional contact details.

            Register the onPaymentAuthorized() callback as part of the PaymentClient initialization as shown in Google Pay's Client Reference page.

            Create an order by using the PayPal Orders V2 API. Use paypal.Googlepay().confirmOrder() to send the orderID, the Google Pay Payment Data, and optional contact details, and confirm the order.

            Confirm the order using the paypal.Googlepay().confirmOrder() method in the API SDK Reference.

            If the order confirmation status is APPROVED, capture the order using the Capture payment for order endpoint of the PayPal Orders V2 API.

            For more details, see step 11 of Google's developer documentation.

              Strong Customer Authentication (SCA)

              When the ConfirmOrder status is PAYER_ACTION_REQUIRED, the order requires additional authentication from the payer, such as 3D Secure.

              The PayPal JavaScript SDK Client provides an API to handle 3DS Secure authentication. Pass the orderId to initiatePayerAction.

              Note: Refer to initiatePayerAction for more details.

              When the payer completes authentication, confirm that the liability_shift status has shifted:

                Test your integration

                Test your Google Pay integration in the PayPal sandbox and production environments to ensure that your app works correctly.

                Sandbox

                Use your personal sandbox login information during checkout to complete a payment using Google Pay. Then, log into the sandbox site sandbox.paypal.com to see that the money has moved into your account.

                1. Open your test page with a supported web browser on any supported device.
                2. Add a test card to your Google Wallet on your device. Google provides test cards through their Test card suite.
                3. Tap the Google Pay button to open a pop-up with the Google Pay payment sheet.
                4. Make a payment using the Google Pay payment sheet.
                5. If you have an additional confirmation page on your merchant website, continue to confirm the payment.
                6. Log in to your merchant account and continue to your confirmation page to confirm that the money you used for payment showed up in the account.
                8

                Go live

                Make Google Pay available to buyers using your website or app.

                Note: Before going live, complete production onboarding to process Google Pay payments with your live PayPal account.

                Live environment

                If you’re a new partner, sign up for a PayPal business account.

                Use your personal production login information during checkout to complete a Google Pay transaction. Then log into paypal.com to see the money move out of your account.

                Use the partners onboarding path to provide Google Pay to sellers on your platform. Your sellers complete the onboarding process, and PayPal automatically handles Know Your Customer (KYC) verification and other checks for you.

                Partners need to do the following to complete onboarding:


                Testing in your live environment

                When testing a purchase in production, consider:

                • The business account receiving money can’t also make the purchase.
                • If you create a personal account with the same information as the business account, those accounts might experience restrictions.

                How to test Google Pay payments in a live environment:

                1. Open your test page with a supported browser.
                2. Select the Google Pay button to open a pop-up with the Google Pay payment sheet.
                3. Proceed with the Google Pay checkout transaction.
                4. If you have an additional confirmation page on your merchant website, continue to confirm the payment.
                5. Log in to your merchant account and confirm that the money has moved into that account.

                Troubleshoot your integration

                Make sure that there are no browser console warnings or errors. The JavaScript SDK configuration attributes have distinct validation checks for input formatting and values.

                If the validation fails, the web browser’s developer console shows warning messages that say which property is incorrect and what you need to do to address the issue. The library generally attempts to revert to the safe default values if missing or incorrect inputs exist.

                Next steps & customizations

                Get started testing, add security to your checkout experience or create customizations for your audience.

                Optional

                Advanced credit and debit card payments

                Add PayPal payment buttons and customized card fields.
