Android アプリが Google Play ストアで配布されている場合は、アプリを Google Pay API と統合できます。また、支払いカードを受け入れるようにアプリを構成することもできます。アプリを統合し、支払いカードを受け入れるように構成するには、このチュートリアルの手順に沿って行ってください。
- ステップ 1: Google Pay API のバージョンを定義する
- ステップ 2: 決済機関にお支払いトークンをリクエストする
- ステップ 3: サポートされている支払いカード ネットワークを定義する
- ステップ 4: 許可されたお支払い方法を記述する
- ステップ 5: PaymentsClient インスタンスを作成する
- ステップ 6: Google Pay API での支払いが可能かどうかを確認する
- ステップ 7: PaymentDataRequest オブジェクトを作成する
- ステップ 8: ユーザー ジェスチャのイベント ハンドラを登録する
- ステップ 9: レスポンス オブジェクトを処理する
- まとめ
ステップ 1: Google Pay API のバージョンを定義する
アプリで使用する Google Pay API のバージョンを宣言します。メジャーとマイナーのバージョンは、渡された各オブジェクトで予想されるフィールドに影響を与え、レスポンスに含まれます。
他のすべてのリクエスト オブジェクトに存在するプロパティを含むベース リクエスト オブジェクトを作成します。
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); }
ステップ 2: 決済機関にお支払いトークンをリクエストする
Google では、決済機関による処理が安全に行われるように、支払人が選択したカードに関する情報を暗号化します。
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"); }}); }}; }
example と exampleGatewayMerchantId を決済機関の該当する値に置き換えます。次の表で、お客様の決済機関の gateway 値と gatewayMerchantId 値を探してください。

PAYMENT_GATEWAY は、販売者が Google Pay API のカード支払い方法を統合する際に最もよく使用されるトークン化タイプです。ご利用の決済機関がサポートされていない場合は、DIRECT 統合によって Google Pay を利用できる場合があります。詳細については、直接トークン化のドキュメントをご覧ください。
ステップ 3: サポートされている支払いカード ネットワークを定義する
アプリで使用可能にするカード ネットワークを定義します。
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"); }
Google Pay API は、Google.com に保存されたカード情報(PAN_ONLY)、または 3D セキュア クリプトグラムで認証された Android デバイス トークン(CRYPTOGRAM_3DS)を返します。
Kotlin
private val allowedCardAuthMethods = JSONArray(listOf( "PAN_ONLY", "CRYPTOGRAM_3DS"))
Java
private static JSONArray getAllowedCardAuthMethods() { return new JSONArray() .put("PAN_ONLY") .put("CRYPTOGRAM_3DS"); }
詳しくは、JSON オブジェクト リファレンスの CardParameters をご覧ください。Android デバイス トークンのサポートについては、サポートされているカード ネットワークのゲートウェイまたは決済代行業者に確認してください。
ステップ 4: 許可された支払い方法を記述する
CARD 支払い方法に対するアプリのサポートを記述するには、サポートされている認証方法とサポートされているカード ネットワークを組み合わせます。
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; }
ベースカード支払い方法オブジェクトを拡張し、アプリに返す必要がある情報(トークン化された支払いデータなど)を記述します。
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; }
サポートされている parameters について詳しくは、JSON オブジェクト リファレンスの CardParameters をご覧ください。
CARD に加えて、Google Pay は PAYPAL によるお支払い方法もサポートしています。お支払い方法として PayPal を Google Pay に追加する方法については、PayPal のデベロッパー向けドキュメントをご覧ください。
ステップ 5: PaymentsClient インスタンスを作成する
Activity の onCreate メソッドで PaymentsClient インスタンスを作成します。PaymentsClient は Google Pay API とのやり取りに使用されます。
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(Activity activity) { Wallet.WalletOptions walletOptions = new Wallet.WalletOptions.Builder().setEnvironment(Constants.PAYMENTS_ENVIRONMENT).build(); return Wallet.getPaymentsClient(activity, walletOptions); }
ステップ 6: Google Pay API での支払いが可能かどうかを確認する
次のコード スニペットを使用して、許可された支払い方法をベース リクエスト オブジェクトに追加します。
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(); } }
Google Pay ボタンを表示する前に isReadyToPay API を呼び出して、ユーザーが Google Pay API で支払いを行えるかどうかを判断します。構成プロパティの一覧については、IsReadyToPayRequest JSON オブジェクトのドキュメントをご覧ください。
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()); } } }); }
例に示すように、isReadyToPay 関数が成功の結果を返した場合にのみ、Google Pay をお支払いオプションとして表示することをおすすめします。Google Pay 支払いボタンを表示する方法として最も一般的なのは、お支払いオプションを実装するときにレイアウト include を通じて表示する方法です。アプリで使用できる Google Pay 支払いボタン、ロゴ、マークについて詳しくは、ブランド ガイドラインをご覧ください。
ステップ 7: PaymentDataRequest オブジェクトを作成する
PaymentDataRequest JSON オブジェクトは、Google Pay 支払いシートで支払人に入力を求める情報を記述します。
取引価格と提供された価格のステータスに関する情報を提供します。詳しくは、TransactionInfo JSON オブジェクトのドキュメントをご覧ください。
次の例に、価格、価格ステータス、通貨取引の情報を取得する方法を示します。
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; }
ユーザーに表示される販売者名を入力します。詳しくは、MerchantInfo JSON オブジェクトのドキュメントをご覧ください。
次の例は、販売者の名前を取得する方法を示します。
Kotlin
private val merchantInfo: JSONObject = JSONObject().put("merchantName", "Example Merchant")
Java
private static JSONObject getMerchantInfo() throws JSONException { return new JSONObject().put("merchantName", "Example Merchant"); }
ベース リクエスト オブジェクトを新しい PaymentDataRequest JSON オブジェクトに割り当てます。次に、レスポンスで値を返すよう求める追加データの構成など、アプリでサポートされる支払い方法を追加します。最後に、取引に関する情報とリクエストを送信した販売者に関する情報を追加します。
次の例は、支払いデータをリクエストする方法を示します。
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(); } }
詳しくは、PaymentDataRequest JSON オブジェクトのドキュメントをご覧ください。
ステップ 8: ユーザー ジェスチャーのイベント ハンドラを登録する
ユーザーが Google Pay 支払いボタンをクリックした後に Google Pay 支払いシートが表示されるようにするには、OnClickListener を定義します。
Kotlin
googlePayButton.setOnClickListener { requestPayment() }
Java
googlePayButton.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View view) { requestPayment(view); } });
PaymentDataRequest オブジェクトは、支払いデータのリクエストを表す Parcelable です。PaymentDataRequest は、支払いのサポートに必要な情報を提供します。AutoResolveHelper クラスを使用して Task を自動的に解決し、その結果を Activity クラスの onActivityResult メソッドで処理します。
ステップ 9: レスポンス オブジェクトを処理する
支払人が Google Pay 支払いシートでリクエストされた情報を正しく提供した後、PaymentData オブジェクトが onActivityResult に返されます。
支払い情報を決済代行業者に渡すため、およびユーザーに購入の確認を提示するために、成功したレスポンスを JSON に変換します。PaymentDataRequest に渡された transactionInfo.totalPriceStatus が ESTIMATED であった場合は、返されたお支払い方法に代金を請求する前に、最終価格を表示する必要があります。
paymentData レスポンスから支払いトークンを抽出します。ゲートウェイ統合を実装する場合は、このトークンをそのままゲートウェイに渡します。
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); } }
レスポンスの内容と構造について詳しくは、PaymentData JSON オブジェクト リファレンスをご覧ください。
まとめ
次のスニペットに、適切に構成されたプロジェクトの完全な例を示します。プロジェクト レベルの設定手順については、プロジェクトを構成するをご覧ください。
