1단계: 결제 구성 정의

Google Pay API 버전 구성

애플리케이션에서 사용하는 Google Pay API 버전을 선언합니다. 주 버전과 부 버전은 전달된 각 객체에서 예상되는 필드에 영향을 미치며 응답에 포함됩니다.

다른 모든 요청 객체에 있는 속성을 포함하는 기본 요청 객체를 만듭니다.

Kotlin

private val baseRequest = JSONObject()
    .put("apiVersion", 2)
    .put("apiVersionMinor", 0)PaymentsUtil.kt

자바

private static JSONObject getBaseRequest() throws JSONException {
  return new JSONObject()
      .put("apiVersion", 2)
      .put("apiVersionMinor", 0);
}PaymentsUtil.java

결제 시스템 공급자의 결제 토큰 요청

Google은 결제 시스템 공급자의 보안 처리를 위해 결제자가 선택한 카드 정보를 암호화합니다.

Kotlin

private fun gatewayTokenizationSpecification(): JSONObject {
    return JSONObject().apply {
        put("type", "PAYMENT_GATEWAY")
        put("parameters", JSONObject(mapOf(
                "gateway" to "example",
                "gatewayMerchantId" to "exampleGatewayMerchantId")))
    }
}

자바

private static JSONObject getGatewayTokenizationSpecification() throws JSONException {
  return new JSONObject()
      .put("type", "PAYMENT_GATEWAY")
      .put("parameters", new JSONObject()
          .put("gateway", "example")
          .put("gatewayMerchantId", "exampleGatewayMerchantId")
      );
}PaymentsUtil.java

도움말: example은 TEST 환경에서 유효한 게이트웨이 이름입니다. API를 사용해 보려면 코드 샘플을 그대로 사용해도 됩니다. example 게이트웨이를 사용하면 API에서 거래할 수 있는 카드 데이터를 반환하지 않지만 사용자 흐름은 동일합니다.

example 및 exampleGatewayMerchantId를 결제 시스템 공급자에 해당하는 값으로 바꿉니다. 다음 표를 참조하여 결제 시스템 공급자의 gateway 및 gatewayMerchantId 값을 찾습니다.

PAYMENT_GATEWAY 토큰화 유형은 Google Pay API로 카드 결제 수단의 판매자를 구현하는 가장 일반적인 방식입니다. 결제 시스템 공급자가 지원되지 않는 경우에는 DIRECT 통합을 통해 Google Pay를 허용하면 됩니다. 자세한 내용은 직접 토큰화 문서를 참고하세요.

지원되는 결제 카드 네트워크 정의

애플리케이션에서 사용할 수 있는 카드 네트워크를 정의합니다.

Kotlin

private val allowedCardNetworks = JSONArray(listOf(
        "AMEX",
        "DISCOVER",
        "INTERAC",
        "JCB",
        "MASTERCARD",
        "VISA"))

자바

private static JSONArray getAllowedCardNetworks() {
  return new JSONArray()
      .put("AMEX")
      .put("DISCOVER")
      .put("INTERAC")
      .put("JCB")
      .put("MASTERCARD")
      .put("VISA");
}

Google Pay API는 계정에 등록된 카드 (PAN_ONLY) 또는 3D Secure 암호(CRYPTOGRAM_3DS)로 인증된 Android 지원 기기의 기기 토큰을 반환할 수 있습니다. 애플리케이션에서 지원하는 메서드를 반환하도록 API를 구성할 수 있습니다.

allowedCardAuthMethods를 설정하기 전에 기기 토큰 (CRYPTOGRAM_3DS)이 해당 리전에서 지원되는지 여부를 결제 대행업체 및 인수자에게 확인하세요.

Kotlin

private val allowedCardAuthMethods = JSONArray(listOf(
        "PAN_ONLY",
        "CRYPTOGRAM_3DS"))

자바

private static JSONArray getAllowedCardAuthMethods() {
  return new JSONArray()
      .put("PAN_ONLY")
      .put("CRYPTOGRAM_3DS");
}

자세한 내용은 CardParameters 객체 참조 문서를 확인하세요. 지원되는 카드 네트워크 및 Android 기기 토큰 지원은 게이트웨이 또는 대행업체를 통해 확인하세요.

사용할 수 있는 결제 수단 설명

애플리케이션에서 CARD 결제 수단을 지원하는 방법을 설명하려면 지원되는 인증 방법과 카드 네트워크를 결합합니다.

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

자바

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

참고: CARD만 지원되는 결제 수단입니다.

결제 수단을 토큰화하는 방법에 관한 정보로 구성을 확장합니다.

Kotlin

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

자바

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

자세한 내용은 CardParameters 객체 참조 문서를 확인하세요.

2단계: PaymentsClient 인스턴스 만들기

Google Pay API와 상호작용할 PaymentsClient 인스턴스를 만듭니다.

Kotlin

fun createPaymentsClient(context: Context): PaymentsClient {
    val walletOptions = Wallet.WalletOptions.Builder()
        .setEnvironment(Constants.PAYMENTS_ENVIRONMENT)
        .build()

    return Wallet.getPaymentsClient(context, walletOptions)
}PaymentsUtil.kt

자바

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

3단계: Google Pay API로 결제할 준비가 되었는지 확인

다음 코드 스니펫을 사용하여 사용할 수 있는 결제 수단을 기본 요청 객체에 추가합니다.

Kotlin

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

자바

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

Google Pay 버튼을 표시하기 전에 isReadyToPay API를 호출하여 사용자가 Google Pay API로 결제할 수 있는지 확인합니다. 구성 속성의 전체 목록은 IsReadyToPayRequest JSON 객체 문서를 참고하세요.

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)
        }
    }
}CheckoutActivity.kt

Kotlin
(코루틴)

private suspend fun fetchCanUseGooglePay(): Boolean {
    val request = IsReadyToPayRequest.fromJson(PaymentsUtil.isReadyToPayRequest().toString())
    return paymentsClient.isReadyToPay(request).await()
}CheckoutViewModel.kt

자바

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());
          }
        }
      });
}CheckoutActivity.java

4단계: Google Pay 결제 버튼 추가

앱에 Google Pay 결제 버튼을 추가하여 쇼핑객이 Google Pay API 및 앱에서 지원하는 결제 수단을 사용하여 결제하도록 유도하세요.

사용 가능한 버튼 유형, 색상, 디스플레이 요구사항에 대한 자세한 내용은 ButtonOptions 참조를 참고하세요.

애플리케이션의 결제 레이아웃에 PayButton 레이아웃을 추가합니다.

Kotlin
(Compose)

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

XML

<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"/>">activity_checkout.xml

참고: Jetpack Compose 요소를 사용하려면 Gradle 빌드 파일의 종속 항목 목록에 com.google.pay.button:compose-pay-button 라이브러리를 추가하세요. 자세한 내용은 compose-pay-button을 참고하세요.

XML을 사용하여 Google Pay 버튼을 추가하는 경우...

Android 활동으로 이동하여 다른 UI 요소와 함께 Google Pay 버튼을 초기화합니다.

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))
}

자바

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

5단계: PaymentDataRequest 객체 만들기

PaymentDataRequest JSON 객체는 Google Pay 결제 명세서에서 결제자에게 요청하는 정보를 설명합니다. 여기에는 거래 가격 및 제공된 가격의 상태에 대한 정보가 포함됩니다. 자세한 내용은 TransactionInfo JSON 객체 문서를 참고하세요.

다음 블록은 Google Pay로 결제 프로세스를 시작하는 데 필요한 PaymentDataRequest 객체에 판매자 및 거래에 관한 정보를 추가합니다.

중요: 유럽 경제 지역 (EEA) 또는 강력한 고객 인증(SCA)이 적용되는 기타 국가에서 거래를 처리하는 판매자는 SCA 요구사항을 충족하기 위해 countryCode, totalPrice, merchantName 매개변수를 포함해야 합니다.

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

자바

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

자바

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

기본 요청 객체를 새 PaymentDataRequest JSON 객체에 할당합니다. 그런 다음 응답에서 예상되는 추가 데이터 구성과 같이 애플리케이션이 지원하는 결제 수단을 추가합니다. 마지막으로 거래 및 요청한 판매자에 대한 정보를 추가합니다.

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.kt

자바

public static JSONObject getPaymentDataRequest(String priceLabel) {
  try {
    return PaymentsUtil.getBaseRequest()
        .put("allowedPaymentMethods", getAllowedPaymentMethods())
        .put("transactionInfo", getTransactionInfo(priceLabel))
        .put("merchantInfo", getMerchantInfo())
        .put("shippingAddressRequired", true)
        .put("shippingAddressParameters", new JSONObject()
            .put("phoneNumberRequired", false)
            .put("allowedCountryCodes", new JSONArray(Constants.SHIPPING_SUPPORTED_COUNTRIES))
        );

  } catch (JSONException e) {
    return null;
  }
}PaymentsUtil.java

PaymentDataRequest 객체는 결제 데이터 요청을 나타내는 Parcelable입니다. PaymentDataRequest는 결제를 지원하는 데 필요한 정보를 제공합니다.

자세한 내용은 PaymentDataRequest JSON 객체 문서를 참고하세요.

6단계: Google Pay로 결제 프로세스 시작

결제 프로세스를 시작하려면 PaymentsClient 객체를 사용하여 loadPaymentData 요청을 호출합니다. 이 호출은 작업 결과가 포함된 Task 객체를 반환합니다.

먼저 이전 단계에서 만든 요청을 사용하여 loadPaymentData 작업을 만듭니다.

Kotlin

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

자바

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

결과를 처리하려면 API에서 활동 결과 계약 중 하나를 사용하세요. 이 예에서는 결과 자체 외에도 작업에 관한 정보가 포함된 객체를 생성하는 GetPaymentDataResult을 사용합니다.

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

자바

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

사용자에게 구매 확인을 표시하기 전에 PaymentData 결과 객체에서 결제 토큰을 추출하고 이 토큰을 사용하여 게이트웨이로 결제 거래를 만듭니다.

결과 객체에 대한 자세한 내용은 PaymentData JSON 객체 참조를 확인하세요.

이제 활동 결과 런처와 작업을 사용하여 Google Pay 결제 선택기를 표시합니다.

Kotlin

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

Kotlin
(코루틴)

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

자바

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
