If your Android application is distributed through the Google Play store, you can integrate it with the Google Pay API. You can also configure it to accept payment cards. To integrate your application and configure it to accept payment cards, follow the steps in this tutorial.
- Step 1: Define your Google Pay API version.
- Step 2: Request a payment token for your payment provider.
- Step 3: Define supported payment card networks.
- Step 4: Describe your allowed payment methods.
- Step 5: Create a PaymentsClient instance.
- Step 6: Determine readiness to pay with the Google Pay API.
- Step 7: Add a Google Pay payment button.
- Step 8: Create a PaymentDataRequest object.
- Step 9: Register event handler for user gesture.
- Step 10: Handle the response object.
- Put it all together.
Step 1: Define your Google Pay API version
Declare the version of the Google Pay API that your application uses. The major and minor versions affect the fields expected in each passed object and are included in the response.
Create a base request object that contains properties that are present in all other request objects.
Kotlin
private val baseRequest = JSONObject().apply {
put("apiVersion", 2)
put("apiVersionMinor", 0)
}
Java
private static JSONObject getBaseRequest() throws JSONException {
return new JSONObject().put("apiVersion", 2).put("apiVersionMinor", 0);
}
Step 2: Request a payment token for your payment provider
Google encrypts information about a payer's selected card for secure processing by a payment provider.
Kotlin
private fun gatewayTokenizationSpecification(): JSONObject {
return JSONObject().apply {
put("type", "PAYMENT_GATEWAY")
put("parameters", JSONObject(mapOf(
"gateway" to "example",
"gatewayMerchantId" to "exampleGatewayMerchantId")))
}
}
Java
private static JSONObject getGatewayTokenizationSpecification() throws JSONException {
return new JSONObject() {{
put("type", "PAYMENT_GATEWAY");
put("parameters", new JSONObject() {{
put("gateway", "example");
put("gatewayMerchantId", "exampleGatewayMerchantId");
}});
}};
}
Replace example and exampleGatewayMerchantId with
the appropriate values for your payment provider. Use the following table to find the specific
gateway and gatewayMerchantId values for your payment provider:

The PAYMENT_GATEWAY tokenization type is the most common merchant implementation
of the card payment method in the Google Pay API. If your payment provider isn't supported, you
might be able to accept Google Pay by a DIRECT integration. For more information, see the
Direct tokenization
documentation.
Step 3: Define supported payment card networks
Define the card networks that your application accepts.
Kotlin
private val allowedCardNetworks = JSONArray(listOf(
"AMEX",
"DISCOVER",
"INTERAC",
"JCB",
"MASTERCARD",
"VISA"))
Java
private static JSONArray getAllowedCardNetworks() {
return new JSONArray()
.put("AMEX")
.put("DISCOVER")
.put("INTERAC")
.put("JCB")
.put("MASTERCARD")
.put("VISA");
}
The Google Pay API might return cards on file on Google.com (PAN_ONLY) or a device
token on an Android-powered device authenticated with a 3-D Secure cryptogram
(CRYPTOGRAM_3DS). You can control whether both methods or just one of them can be
returned.
Before you set allowedCardAuthMethods, confirm with your payment processor and
acquirer on whether device tokens (CRYPTOGRAM_3DS) are supported in your region.
Kotlin
private val allowedCardAuthMethods = JSONArray(listOf(
"PAN_ONLY",
"CRYPTOGRAM_3DS"))
Java
private static JSONArray getAllowedCardAuthMethods() {
return new JSONArray()
.put("PAN_ONLY")
.put("CRYPTOGRAM_3DS");
}
For more information, see
CardParameters
in our JSON object reference. For Android device tokens support, check with your gateway or
processor for the card networks supported.
Step 4: Describe your allowed payment methods
In order to describe your application's support for the CARD payment method, combine
your supported authentication methods and supported card networks.
Kotlin
private fun baseCardPaymentMethod(): JSONObject {
return JSONObject().apply {
val parameters = JSONObject().apply {
put("allowedAuthMethods", allowedCardAuthMethods)
put("allowedCardNetworks", allowedCardNetworks)
put("billingAddressRequired", true)
put("billingAddressParameters", JSONObject().apply {
put("format", "FULL")
})
}
put("type", "CARD")
put("parameters", parameters)
}
}
Java
private static JSONObject getBaseCardPaymentMethod() throws JSONException {
JSONObject cardPaymentMethod = new JSONObject();
cardPaymentMethod.put("type", "CARD");
JSONObject parameters = new JSONObject();
parameters.put("allowedAuthMethods", getAllowedCardAuthMethods());
parameters.put("allowedCardNetworks", getAllowedCardNetworks());
// Optionally, you can add billing address/phone number associated with a CARD payment method.
parameters.put("billingAddressRequired", true);
JSONObject billingAddressParameters = new JSONObject();
billingAddressParameters.put("format", "FULL");
parameters.put("billingAddressParameters", billingAddressParameters);
cardPaymentMethod.put("parameters", parameters);
return cardPaymentMethod;
}
Extend the base card payment method object to describe information expected to be returned to your application, which must include tokenized payment data.
Kotlin
private fun cardPaymentMethod(): JSONObject {
val cardPaymentMethod = baseCardPaymentMethod()
cardPaymentMethod.put("tokenizationSpecification", gatewayTokenizationSpecification())
return cardPaymentMethod
}
Java
private static JSONObject getCardPaymentMethod() throws JSONException {
JSONObject cardPaymentMethod = getBaseCardPaymentMethod();
cardPaymentMethod.put("tokenizationSpecification", getGatewayTokenizationSpecification());
return cardPaymentMethod;
}
For more information about supported parameters, see
CardParameters
in our JSON object reference.
CARD is currently the only supported payment method.
Step 5: Create a PaymentsClient instance
Create a
PaymentsClient
instance. The PaymentsClient is used for interaction with the Google Pay API.
Kotlin
fun createPaymentsClient(activity: Activity): PaymentsClient {
val walletOptions = Wallet.WalletOptions.Builder()
.setEnvironment(Constants.PAYMENTS_ENVIRONMENT)
.build()
return Wallet.getPaymentsClient(activity, walletOptions)
}
Java
public static PaymentsClient createPaymentsClient(Context context) {
Wallet.WalletOptions walletOptions =
new Wallet.WalletOptions.Builder().setEnvironment(Constants.PAYMENTS_ENVIRONMENT).build();
return Wallet.getPaymentsClient(context, walletOptions);
}
Step 6: Determine readiness to pay with the Google Pay API
Add your allowed payment methods to your base request object with the following code snippet:
Kotlin
fun isReadyToPayRequest(): JSONObject? {
return try {
baseRequest.apply {
put("allowedPaymentMethods", JSONArray().put(baseCardPaymentMethod()))
}
} catch (e: JSONException) {
null
}
}
Java
public static Optional<JSONObject> getIsReadyToPayRequest() {
try {
JSONObject isReadyToPayRequest = getBaseRequest();
isReadyToPayRequest.put(
"allowedPaymentMethods", new JSONArray().put(getBaseCardPaymentMethod()));
return Optional.of(isReadyToPayRequest);
} catch (JSONException e) {
return Optional.empty();
}
}
Before you display the Google Pay button, call the isReadyToPay API to determine if the user can
make payments with the Google Pay API. For a full list of configuration properties, see the
IsReadyToPayRequest JSON object documentation.
Kotlin
private fun possiblyShowGooglePayButton() {
val isReadyToPayJson = PaymentsUtil.isReadyToPayRequest() ?: return
val request = IsReadyToPayRequest.fromJson(isReadyToPayJson.toString()) ?: return
// The call to isReadyToPay is asynchronous and returns a Task. We need to provide an
// OnCompleteListener to be triggered when the result of the call is known.
val task = paymentsClient.isReadyToPay(request)
task.addOnCompleteListener { completedTask ->
try {
completedTask.getResult(ApiException::class.java)?.let(::setGooglePayAvailable)
} catch (exception: ApiException) {
// Process error
Log.w("isReadyToPay failed", exception)
}
}
}
Java
private void possiblyShowGooglePayButton() {
final Optional<JSONObject> isReadyToPayJson = PaymentsUtil.getIsReadyToPayRequest();
if (!isReadyToPayJson.isPresent()) {
return;
}
// The call to isReadyToPay is asynchronous and returns a Task. We need to provide an
// OnCompleteListener to be triggered when the result of the call is known.
IsReadyToPayRequest request = IsReadyToPayRequest.fromJson(isReadyToPayJson.get().toString());
Task<Boolean> task = paymentsClient.isReadyToPay(request);
task.addOnCompleteListener(this,
new OnCompleteListener<Boolean>() {
@Override
public void onComplete(@NonNull Task<Boolean> task) {
if (task.isSuccessful()) {
setGooglePayAvailable(task.getResult());
} else {
Log.w("isReadyToPay failed", task.getException());
}
}
});
}
As the example shows, it's best to show Google Pay as a payment option only after you receive
a successful result from the isReadyToPay function. It's most common to display a
Google Pay payment button through a layout include when you implement a payment
option. For more information about Google Pay payment buttons, logos, and marks available for use
in your application, see
Brand guidelines.
Step 7: Add a Google Pay payment button
Add a Google Pay payment button to your app to encourage shoppers to check out with payment methods that are supported by the Google Pay API and your app. For more information about available button types, colors, and display requirements, see the ButtonOptions.
Add the PayButton layout to your application’s checkout layout, which is
commonly on the app/main/res/layout/activity_checkout.xml:
Kotlin
<com.google.android.gms.wallet.button.PayButton
android:id="@+id/googlePayButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"/>
Java
<com.google.android.gms.wallet.button.PayButton
android:id="@+id/googlePayButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"/>
In the Android activity (for example, in the onCreate method), initialize the
payment button:
Kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// Use view binding to access the UI elements
layout = ActivityCheckoutBinding.inflate(layoutInflater)
setContentView(layout.root)
// Setup buttons
googlePayButton = layout.googlePayButton
googlePayButton.initialize(
ButtonOptions.newBuilder()
.setAllowedPaymentMethods(PaymentsUtil.allowedPaymentMethods.toString()).build()
)
googlePayButton.setOnClickListener { requestPayment() }
addToGoogleWalletButton = layout.addToGoogleWalletButton.root
addToGoogleWalletButton.setOnClickListener { requestSavePass() }
// Check Google Pay availability
model.canUseGooglePay.observe(this, Observer(::setGooglePayAvailable))
model.canSavePasses.observe(this, Observer(::setAddToGoogleWalletAvailable))
}
Java
private void initializeUi() {
// Use view binding to access the UI elements
layoutBinding = ActivityCheckoutBinding.inflate(getLayoutInflater());
setContentView(layoutBinding.getRoot());
// The Google Pay button is a layout file – take the root view
googlePayButton = layoutBinding.googlePayButton.getRoot();
googlePayButton.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View view) {
requestPayment(view);
}
});
}
Step 8: Create a PaymentDataRequest object
A
PaymentDataRequest JSON object
describes the information that you request from a payer in a Google Pay payment sheet.
Provide information about the transaction price and the status of the provided price. For more
information, see
TransactionInfo JSON object documentation.
The following example shows how to get price, price status, and currency transaction information.
Kotlin
private fun getTransactionInfo(price: String): JSONObject {
return JSONObject().apply {
put("totalPrice", price)
put("totalPriceStatus", "FINAL")
put("countryCode", Constants.COUNTRY_CODE)
put("currencyCode", Constants.CURRENCY_CODE)
}
}
Java
private static JSONObject getTransactionInfo(String price) throws JSONException {
JSONObject transactionInfo = new JSONObject();
transactionInfo.put("totalPrice", price);
transactionInfo.put("totalPriceStatus", "FINAL");
transactionInfo.put("countryCode", Constants.COUNTRY_CODE);
transactionInfo.put("currencyCode", Constants.CURRENCY_CODE);
transactionInfo.put("checkoutOption", "COMPLETE_IMMEDIATE_PURCHASE");
return transactionInfo;
}
Provide a user-visible merchant name. For more information, see the
MerchantInfo JSON object documentation.
The following example shows how to get the merchant's name:
Kotlin
private val merchantInfo: JSONObject =
JSONObject().put("merchantName", "Example Merchant")
Java
private static JSONObject getMerchantInfo() throws JSONException {
return new JSONObject().put("merchantName", "Example Merchant");
}
Assign your base request object to a new PaymentDataRequest JSON object.
Then, add the payment methods supported by your application, such as any configuration of additional data
expected in the response. Finally, add information about the transaction and the merchant who makes the request.
The following example shows how to request payment data:
Kotlin
fun getPaymentDataRequest(price: String): JSONObject? {
try {
return baseRequest.apply {
put("allowedPaymentMethods", JSONArray().put(cardPaymentMethod()))
put("transactionInfo", getTransactionInfo(price))
put("merchantInfo", merchantInfo)
// An optional shipping address requirement is a top-level property of the
// PaymentDataRequest JSON object.
val shippingAddressParameters = JSONObject().apply {
put("phoneNumberRequired", false)
put("allowedCountryCodes", JSONArray(listOf("US", "GB")))
}
put("shippingAddressParameters", shippingAddressParameters)
put("shippingAddressRequired", true)
}
} catch (e: JSONException) {
return null
}
}
Java
public static Optional<JSONObject> getPaymentDataRequest(long priceCents) {
final String price = PaymentsUtil.centsToString(priceCents);
try {
JSONObject paymentDataRequest = PaymentsUtil.getBaseRequest();
paymentDataRequest.put(
"allowedPaymentMethods", new JSONArray().put(PaymentsUtil.getCardPaymentMethod()));
paymentDataRequest.put("transactionInfo", PaymentsUtil.getTransactionInfo(price));
paymentDataRequest.put("merchantInfo", PaymentsUtil.getMerchantInfo());
/* An optional shipping address requirement is a top-level property of the PaymentDataRequest
JSON object. */
paymentDataRequest.put("shippingAddressRequired", true);
JSONObject shippingAddressParameters = new JSONObject();
shippingAddressParameters.put("phoneNumberRequired", false);
JSONArray allowedCountryCodes = new JSONArray(Constants.SHIPPING_SUPPORTED_COUNTRIES);
shippingAddressParameters.put("allowedCountryCodes", allowedCountryCodes);
paymentDataRequest.put("shippingAddressParameters", shippingAddressParameters);
return Optional.of(paymentDataRequest);
} catch (JSONException e) {
return Optional.empty();
}
}
For more information, see the
PaymentDataRequest JSON object documentation.
Step 9: Register event handler for user gesture
To request display of a Google Pay payment sheet after user activation of a Google Pay payment
button, define an
OnClickListener.
Kotlin
googlePayButton.setOnClickListener { requestPayment() }
Java
googlePayButton.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View view) {
requestPayment(view);
}
});
The
PaymentDataRequest
object is a
Parcelable
that represents a payment data request. The PaymentDataRequest provides information
that's necessary in order to support a payment. Use the
AutoResolveHelper
class to auto resolve the
Task, then handle
the result in the
onActivityResult method of your Activity class.
Step 10: Handle the response object
After a payer successfully provides the requested information in the Google Pay payment sheet, a
PaymentData
object is returned to onActivityResult.
To pass payment information to your processor and to present the user with a
confirmation of their purchase, convert a successful response to JSON. If the
transactionInfo.totalPriceStatus passed to PaymentDataRequest is
ESTIMATED, you must show a final price before you charge the returned
payment method.
Extract the payment token from the paymentData response. If you implement a gateway
integration, pass this token to your gateway without any modifications.
Kotlin
public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
when (requestCode) {
// Value passed in AutoResolveHelper
LOAD_PAYMENT_DATA_REQUEST_CODE -> {
when (resultCode) {
RESULT_OK ->
data?.let { intent ->
PaymentData.getFromIntent(intent)?.let(::handlePaymentSuccess)
}
RESULT_CANCELED -> {
// The user cancelled the payment attempt
}
AutoResolveHelper.RESULT_ERROR -> {
AutoResolveHelper.getStatusFromIntent(data)?.let {
handleError(it.statusCode)
}
}
}
// Re-enables the Google Pay payment button.
googlePayButton.isClickable = true
}
}
}
Java
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
// value passed in AutoResolveHelper
case LOAD_PAYMENT_DATA_REQUEST_CODE:
switch (resultCode) {
case Activity.RESULT_OK:
PaymentData paymentData = PaymentData.getFromIntent(data);
handlePaymentSuccess(paymentData);
break;
case Activity.RESULT_CANCELED:
// The user cancelled the payment attempt
break;
case AutoResolveHelper.RESULT_ERROR:
Status status = AutoResolveHelper.getStatusFromIntent(data);
handleError(status.getStatusCode());
break;
}
// Re-enables the Google Pay payment button.
googlePayButton.setClickable(true);
}
}
For more information about the content and structure of the response, see the
PaymentData JSON object reference.
Put it all together
The following snippet shows a complete example for a properly configured project. For the project-level setup steps, see Configure your project.
CheckoutActivity.kt (Kotlin)
This example Activity assumes a Google Pay payment button with an
id attribute of googlepay_button exists in your layout.
