Tutorial

Follow the steps in this tutorial to add Google Pay to your Android application and configure it to accept payment cards.

Step 1: Define your payment configuration
Step 2: Create a PaymentsClient instance
Step 3: Determine readiness to pay with the Google Pay API
Step 4: Enhance your checkout with payment metadata API
Step 5: Add a Google Pay payment button
Step 6: Create a PaymentDataRequest object
Step 7: Initiate the payment process with Google Pay
Put it all together

Step 1: Define your payment configuration

Configure 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.

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

 {

Tip: example is a valid gateway name in the TEST environment. If you want to try out the API, you can leave the code sample as-is. When you use the example gateway, the API doesn't return card data capable of a transaction, but the user flow looks the same.

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 .

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 from your account ( PAN_ONLY ) or a device token on an Android-powered device authenticated with a 3-D Secure cryptogram ( CRYPTOGRAM_3DS ). You can configure the API to return the methods that your application supports.

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 the reference documentation for the CardParameters object . For Android device tokens support, check with your gateway or processor for the card networks supported.

Describe your allowed payment methods

In order to describe your application's support for the CARD payment method, combine your supported authentication methods and card networks.

Kotlin

 private 
  
 fun 
  
 baseCardPaymentMethod 
 (): 
  
 JSONObject 
  
 = 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "type" 
 , 
  
 "CARD" 
 ) 
  
 . 
 put 
 ( 
 "parameters" 
 , 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "allowedAuthMethods" 
 , 
  
 allowedCardAuthMethods 
 ) 
  
 . 
 put 
 ( 
 "allowedCardNetworks" 
 , 
  
 allowedCardNetworks 
 ) 
  
 . 
 put 
 ( 
 "billingAddressRequired" 
 , 
  
 true 
 ) 
  
 . 
 put 
 ( 
 "billingAddressParameters" 
 , 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "format" 
 , 
  
 "FULL" 
 ) 
  
 ) 
  
 ) 
   PaymentsUtil 
 . 
 kt

Java

 private 
  
 static 
  
 JSONObject 
  
 getBaseCardPaymentMethod 
 () 
  
 throws 
  
 JSONException 
  
 { 
  
 return 
  
 new 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "type" 
 , 
  
 "CARD" 
 ) 
  
 . 
 put 
 ( 
 "parameters" 
 , 
  
 new 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "allowedAuthMethods" 
 , 
  
 getAllowedCardAuthMethods 
 ()) 
  
 . 
 put 
 ( 
 "allowedCardNetworks" 
 , 
  
 getAllowedCardNetworks 
 ()) 
  
 . 
 put 
 ( 
 "billingAddressRequired" 
 , 
  
 true 
 ) 
  
 . 
 put 
 ( 
 "billingAddressParameters" 
 , 
  
 new 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "format" 
 , 
  
 "FULL" 
 ) 
  
 ) 
  
 ); 
 } 
   PaymentsUtil 
 . 
 java

Note: CARD is the only supported payment method.

Extend your configuration with information about how to tokenize the payment method.

Kotlin

 private 
  
 val 
  
 cardPaymentMethod 
 : 
  
 JSONObject 
  
 = 
  
 baseCardPaymentMethod 
 () 
  
 . 
 put 
 ( 
 "tokenizationSpecification" 
 , 
  
 gatewayTokenizationSpecification 
 ) 
   PaymentsUtil 
 . 
 kt

Java

 private 
  
 static 
  
 JSONObject 
  
 getCardPaymentMethod 
 () 
  
 throws 
  
 JSONException 
  
 { 
  
 return 
  
 getBaseCardPaymentMethod 
 () 
  
 . 
 put 
 ( 
 "tokenizationSpecification" 
 , 
  
 getGatewayTokenizationSpecification 
 ()); 
 } 
   PaymentsUtil 
 . 
 java

For more information, see the reference documentation for the CardParameters object .

Step 2: Create a PaymentsClient instance

Create a PaymentsClient instance to interact with the Google Pay API.

Kotlin

 fun 
  
 createPaymentsClient 
 ( 
 context 
 : 
  
 Context 
 ): 
  
 PaymentsClient 
  
 { 
  
 val 
  
 walletOptions 
  
 = 
  
 Wallet 
 . 
 WalletOptions 
 . 
 Builder 
 () 
  
 . 
 setEnvironment 
 ( 
 Constants 
 . 
 PAYMENTS_ENVIRONMENT 
 ) 
  
 . 
 build 
 () 
  
 return 
  
 Wallet 
 . 
 getPaymentsClient 
 ( 
 context 
 , 
  
 walletOptions 
 ) 
 } 
   PaymentsUtil 
 . 
 kt

Java

 public 
  
 static 
  
 PaymentsClient 
  
 createPaymentsClient 
 ( 
 Context 
  
 context 
 ) 
  
 { 
  
 Wallet 
 . 
 WalletOptions 
  
 walletOptions 
  
 = 
  
 new 
  
 Wallet 
 . 
 WalletOptions 
 . 
 Builder 
 (). 
 setEnvironment 
 ( 
 Constants 
 . 
 PAYMENTS_ENVIRONMENT 
 ). 
 build 
 (); 
  
 return 
  
 Wallet 
 . 
 getPaymentsClient 
 ( 
 context 
 , 
  
 walletOptions 
 ); 
 } 
   PaymentsUtil 
 . 
 java

Step 3: 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? 
 = 
  
 try 
  
 { 
  
 baseRequest 
  
 . 
 put 
 ( 
 "allowedPaymentMethods" 
 , 
  
 JSONArray 
 (). 
 put 
 ( 
 baseCardPaymentMethod 
 ())) 
  
 } 
  
 catch 
  
 ( 
 e 
 : 
  
 JSONException 
 ) 
  
 { 
  
 null 
  
 } 
   PaymentsUtil 
 . 
 kt

Java

 public 
  
 static 
  
 JSONObject 
  
 getIsReadyToPayRequest 
 () 
  
 { 
  
 try 
  
 { 
  
 return 
  
 getBaseRequest 
 () 
  
 . 
 put 
 ( 
 "allowedPaymentMethods" 
 , 
  
 new 
  
 JSONArray 
 (). 
 put 
 ( 
 getBaseCardPaymentMethod 
 ())); 
  
 } 
  
 catch 
  
 ( 
 JSONException 
  
 e 
 ) 
  
 { 
  
 return 
  
 null 
 ; 
  
 } 
 } 
   PaymentsUtil 
 . 
 java

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

Step 5: 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 reference.

Add the PayButton layout to your application's checkout layout:

Kotlin
(Compose)

 PayButton 
 ( 
  
 modifier 
  
 = 
  
 Modifier 
  
 . 
 testTag 
 ( 
 "payButton" 
 ) 
  
 . 
 fillMaxWidth 
 (), 
  
 onClick 
  
 = 
  
 onGooglePayButtonClick 
 , 
  
 allowedPaymentMethods 
  
 = 
  
 PaymentsUtil 
 . 
 allowedPaymentMethods 
 . 
 toString 
 () 
   CheckoutLayout 
 . 
 kt

XML

< com 
 . 
 google 
 . 
 android 
 . 
 gms 
 . 
 wallet 
 .

 . 
 PayButton 
  
 android

 id 
 = 
 "@+id/googlePayButton" 
  
 android 
 : 
 layout_width 
 = 
 "match_parent" 
  
 android 
 : 
 layout_height 
 = 
 "wrap_content" 
  
 android 
 : 
 layout_marginBottom 
 = 
 "20dp" 
 / 
>  ">activity_checkout.xml

Note : To use the Jetpack Compose element, add the com.google.pay.button:compose-pay-button library to the list of dependencies in your Gradle build file. For more information, see compose-pay-button .

If you are adding the Google Pay button using XML...

Go to the Android activity and initialize the Google Pay button alongside other UI elements:

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 
 () 
  
 } 
  
 // Check Google Pay availability 
  
 model 
 . 
 canUseGooglePay 
 . 
 observe 
 ( 
 this 
 , 
  
 Observer 
 ( 
 :: 
 setGooglePayAvailable 
 )) 
 }

Java

 private 
  
 void 
  
 initializeUi 
 () 
  
 { 
  
 // Use view binding to access the UI elements 
  
 ActivityCheckoutBinding 
  
 layoutBinding 
  
 = 
  
 ActivityCheckoutBinding 
 . 
 inflate 
 ( 
 getLayoutInflater 
 ()); 
  
 setContentView 
 ( 
 layoutBinding 
 . 
 getRoot 
 ()); 
  
 // The Google Pay button is a layout file – take the root view 
  
 googlePayButton 
  
 = 
  
 layoutBinding 
 . 
 googlePayButton 
 ; 
  
 try 
  
 { 
  
 googlePayButton 
 . 
 initialize 
 ( 
  
 ButtonOptions 
 . 
 newBuilder 
 () 
  
 . 
 setAllowedPaymentMethods 
 ( 
 PaymentsUtil 
 . 
 getAllowedPaymentMethods 
 (). 
 toString 
 ()). 
 build 
 () 
  
 ); 
  
 googlePayButton 
 . 
 setOnClickListener 
 ( 
 this 
 :: 
 requestPayment 
 ); 
  
 } 
  
 catch 
  
 ( 
 JSONException 
  
 e 
 ) 
  
 { 
  
 // Keep Google Pay button hidden (consider logging this to your app analytics service) 
  
 } 
 } 
   CheckoutActivity 
 . 
 java

Step 6: Create a PaymentDataRequest object

A PaymentDataRequest JSON object describes the information that you request from a payer in a Google Pay payment sheet. This includes information about the transaction price and the status of the provided price. For more information, see TransactionInfo JSON object documentation .

The following blocks add information about the merchant and the transaction to the PaymentDataRequest object needed to start the payment process with Google Pay.

Important: Merchants that process transactions in the European Economic Area (EEA) or any other countries that are subject to Strong Customer Authentication (SCA) must include the countryCode , totalPrice , and merchantName parameters to meet SCA requirements.

Kotlin

 private 
  
 fun 
  
 getTransactionInfo 
 ( 
 price 
 : 
  
 String 
 ): 
  
 JSONObject 
  
 = 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "totalPrice" 
 , 
  
 price 
 ) 
  
 . 
 put 
 ( 
 "totalPriceStatus" 
 , 
  
 "FINAL" 
 ) 
  
 . 
 put 
 ( 
 "countryCode" 
 , 
  
 Constants 
 . 
 COUNTRY_CODE 
 ) 
  
 . 
 put 
 ( 
 "currencyCode" 
 , 
  
 Constants 
 . 
 CURRENCY_CODE 
 ) 
   PaymentsUtil 
 . 
 kt

Java

 private 
  
 static 
  
 JSONObject 
  
 getTransactionInfo 
 ( 
 String 
  
 price 
 ) 
  
 throws 
  
 JSONException 
  
 { 
  
 return 
  
 new 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "totalPrice" 
 , 
  
 price 
 ) 
  
 . 
 put 
 ( 
 "totalPriceStatus" 
 , 
  
 "FINAL" 
 ) 
  
 . 
 put 
 ( 
 "countryCode" 
 , 
  
 Constants 
 . 
 COUNTRY_CODE 
 ) 
  
 . 
 put 
 ( 
 "currencyCode" 
 , 
  
 Constants 
 . 
 CURRENCY_CODE 
 ) 
  
 . 
 put 
 ( 
 "checkoutOption" 
 , 
  
 "COMPLETE_IMMEDIATE_PURCHASE" 
 ); 
 } 
   PaymentsUtil 
 . 
 java

Kotlin

 private 
  
 val 
  
 merchantInfo 
 : 
  
 JSONObject 
  
 = 
  
 JSONObject 
 (). 
 put 
 ( 
 "merchantName" 
 , 
  
 "Example Merchant" 
 ) 
   PaymentsUtil 
 . 
 kt

Java

 private 
  
 static 
  
 JSONObject 
  
 getMerchantInfo 
 () 
  
 throws 
  
 JSONException 
  
 { 
  
 return 
  
 new 
  
 JSONObject 
 (). 
 put 
 ( 
 "merchantName" 
 , 
  
 "Example Merchant" 
 ); 
 } 
   PaymentsUtil 
 . 
 java

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:

Kotlin

 fun 
  
 getPaymentDataRequest 
 ( 
 priceLabel 
 : 
  
 String 
 ): 
  
 JSONObject 
  
 = 
  
 baseRequest 
  
 . 
 put 
 ( 
 "allowedPaymentMethods" 
 , 
  
 allowedPaymentMethods 
 ) 
  
 . 
 put 
 ( 
 "transactionInfo" 
 , 
  
 getTransactionInfo 
 ( 
 priceLabel 
 )) 
  
 . 
 put 
 ( 
 "merchantInfo" 
 , 
  
 merchantInfo 
 ) 
  
 . 
 put 
 ( 
 "shippingAddressRequired" 
 , 
  
 true 
 ) 
  
 . 
 put 
 ( 
 "shippingAddressParameters" 
 , 
  
 JSONObject 
 () 
  
 . 
 put 
 ( 
 "phoneNumberRequired" 
 , 
  
 false 
 ) 
  
 . 
 put 
 ( 
 "allowedCountryCodes" 
 , 
  
 JSONArray 
 ( 
 listOf 
 ( 
 "US" 
 , 
  
 "GB" 
 ))) 
  
 ) 
   PaymentsUtil 
 .

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.

For more information, see the PaymentDataRequest JSON object documentation .

Step 7: Initiate the payment process with Google Pay

To start the payment process, call the loadPaymentData request using the PaymentsClient object. This call returns a Task object with the result of the operation.

First, create the loadPaymentData task, using the request created in the previous step:

Kotlin

 fun 
  
 getLoadPaymentDataTask 
 ( 
 priceLabel 
 : 
  
 String 
 ): 
  
 Task<PaymentData> 
  
 { 
  
 val 
  
 paymentDataRequestJson 
  
 = 
  
 PaymentsUtil 
 . 
 getPaymentDataRequest 
 ( 
 priceLabel 
 ) 
  
 val 
  
 request 
  
 = 
  
 PaymentDataRequest 
 . 
 fromJson 
 ( 
 paymentDataRequestJson 
 . 
 toString 
 ()) 
  
 return 
  
 paymentsClient 
 . 
 loadPaymentData 
 ( 
 request 
 ) 
 } 
   CheckoutViewModel 
 . 
 kt

Java

 public 
  
 Task<PaymentData> 
  
 getLoadPaymentDataTask 
 ( 
 String 
  
 priceLabel 
 ) 
  
 { 
  
 JSONObject 
  
 paymentDataRequestJson 
  
 = 
  
 PaymentsUtil 
 . 
 getPaymentDataRequest 
 ( 
 priceLabel 
 ); 
  
 if 
  
 ( 
 paymentDataRequestJson 
  
 == 
  
 null 
 ) 
  
 { 
  
 return 
  
 null 
 ; 
  
 } 
  
 PaymentDataRequest 
  
 request 
  
 = 
  
 PaymentDataRequest 
 . 
 fromJson 
 ( 
 paymentDataRequestJson 
 . 
 toString 
 ()); 
  
 return 
  
 paymentsClient 
 . 
 loadPaymentData 
 ( 
 request 
 ); 
 } 
   getLoadPaymentDataTask 
 ">CheckoutViewModel.java

To process the result, use one of the activity result contracts in the API. This example uses GetPaymentDataResult which yields an object with information about the operation in addition to the result itself:

Kotlin

 private 
  
 val 
  
 paymentDataLauncher 
  
 = 
  
 registerForActivityResult 
 ( 
 GetPaymentDataResult 
 ()) 
  
 { 
  
 taskResult 
  
 - 
>  
 when 
  
 ( 
 taskResult 
 . 
 status 
 . 
 statusCode 
 ) 
  
 { 
  
 CommonStatusCodes 
 . 
 SUCCESS 
  
 - 
>  
 { 
  
 taskResult 
 . 
 result 
 !! 
 . 
 let 
  
 { 
  
 Log 
 . 
 i 
 ( 
 "Google Pay result:" 
 , 
  
 it 
 . 
 toJson 
 ()) 
  
 model 
 . 
 setPaymentData 
 ( 
 it 
 ) 
  
 } 
  
 } 
  
 //CommonStatusCodes.CANCELED -> The user canceled 
  
 //CommonStatusCodes.DEVELOPER_ERROR -> The API returned an error (it.status: Status) 
  
 //else -> Handle internal and other unexpected errors 
  
 } 
 } 
   CheckoutActivity 
 . 
 kt

Java

 private 
  
 final 
  
 ActivityResultLauncher<Task<PaymentData> 
>  
 paymentDataLauncher 
  
 = 
  
 registerForActivityResult 
 ( 
 new 
  
 GetPaymentDataResult 
 (), 
  
 result 
  
 - 
>  
 { 
  
 int 
  
 statusCode 
  
 = 
  
 result 
 . 
 getStatus 
 (). 
 getStatusCode 
 (); 
  
 switch 
  
 ( 
 statusCode 
 ) 
  
 { 
  
 case 
  
 CommonStatusCodes 
 . 
 SUCCESS 
 : 
  
 handlePaymentSuccess 
 ( 
 result 
 . 
 getResult 
 ()); 
  
 break 
 ; 
  
 //case CommonStatusCodes.CANCELED: The user canceled 
  
 case 
  
 CommonStatusCodes 
 . 
 DEVELOPER_ERROR 
 : 
  
 handleError 
 ( 
 statusCode 
 , 
  
 result 
 . 
 getStatus 
 (). 
 getStatusMessage 
 ()); 
  
 break 
 ; 
  
 default 
 : 
  
 handleError 
 ( 
 statusCode 
 , 
  
 "Unexpected non API" 
  
 + 
  
 " exception when trying to deliver the task result to an activity!" 
 ); 
  
 break 
 ; 
  
 } 
  
 }); 
  >  
 paymentDataLauncher 
 ">CheckoutActivity.java

Before presenting the user with a confirmation of their purchase, extract the payment token from the PaymentData result object, and use this token to create the payment transaction with your gateway.

For more information about the result object, see the PaymentData JSON object reference .

Now, use the activity result launcher and the task to show the Google Pay payment selector:

Kotlin

 private 
  
 fun 
  
 requestPayment 
 () 
  
 { 
  
 val 
  
 task 
  
 = 
  
 model 
 . 
 getLoadPaymentDataTask 
 ( 
 priceLabel 
  
 = 
  
 "50.2" 
 ) 
  
 task 
 . 
 addOnCompleteListener 
 ( 
 paymentDataLauncher 
 :: 
 launch 
 ) 
 } 
   CheckoutActivity 
 . 
 kt

Kotlin
(coroutines)

 private 
  
 fun 
  
 requestPayment 
 () 
  
 { 
  
 lifecycleScope 
 . 
 launch 
  
 { 
  
 val 
  
 task 
  
 = 
  
 model 
 . 
 getLoadPaymentDataTask 
 ( 
 priceLabel 
  
 = 
  
 "50.2" 
 ) 
  
 paymentDataLauncher 
 . 
 launch 
 ( 
 task 
 . 
 awaitTask 
 ()) 
  
 } 
 } 
   CheckoutActivity 
 . 
 kt

Java

 public 
  
 void 
  
 requestPayment 
 ( 
 View 
  
 view 
 ) 
  
 { 
  
 // The price provided to the API should include taxes and shipping. 
  
 final 
  
 Task<PaymentData> 
  
 task 
  
 = 
  
 model 
 . 
 getLoadPaymentDataTask 
 ( 
 "50.2" 
 ); 
  
 task 
 . 
 addOnCompleteListener 
 ( 
 paymentDataLauncher 
 :: 
 launch 
 ); 
 } 
   CheckoutActivity 
 . 
 java
