パスはさまざまな用途で利用できますが、それらすべてに共通する使用方法があります。たとえば、ポイントカード、ギフトカード、クーポン、イベント チケット、搭乗券、乗車券はすべて、いくつかの方法で Google Pay アプリに追加できます。以下のいずれかの方法を選択して、詳細をご覧ください。
ウェブボタンを追加する
貴社のウェブサイトに [Google Pay に保存] ボタンを追加し、ユーザーがポイントカード、ギフトカード、クーポン、イベント チケット、搭乗券、乗車券を Google Pay アプリに保存できるようにします。
ユーザーがこのボタンをクリックすると、該当するパスを表す JSON Web Token（JWT）が Google サーバーに送信されます。Google サーバーはその JWT に基づいて Object リソースを作成し、そのリソースをユーザーのアカウントに接続します。
[Google Pay に保存] ボタンは、次の 3 つのステップでウェブサイトに統合できます。
- オブジェクトを拡張する
Classを定義する。 Objectを表す JWT を生成する。- [Google Pay に保存] ボタンをウェブページに追加する。
次のステップではポイントパスを使用しますが、プロセスはすべてのパスで共通です。
1. オブジェクトを拡張するクラスを定義する
最初に LoyaltyClass を定義します。LoyaltyClass を挿入するには、次の REST URI に POST リクエストを送信します。
https://walletobjects.googleapis.com/walletobjects/v1/loyaltyClass
厳密なエラー解析を有効にして ID フィールド重複などのエラーも検出するには、次の例のように strict=true パラメータを REST URI に追加します。
https://walletobjects.googleapis.com/walletobjects/v1/loyaltyClass?strict=true
次の例は、LoyaltyClass を表す JSON リソースを示しています。JSON は POST リクエストの本文に含めて送信する必要があります。次のコードサンプルは、LoyaltyClass を定義して挿入する方法を具体的に示しています。

// Generate the Save to Android Pay Jwt
signer = crypt.Signer.from_string(app_key)
signed_jwt = crypt.make_signed_jwt(signer, jwt)
response = webapp2.Response(signed_jwt)
エンコードされた JWT の安全な長さは 1,800 文字までです。この上限を超えないようにしてください。1,800 文字を超えると、ウェブブラウザによる切り捨てが発生し、保存できないことがあります。JWT でエンコードされるオブジェクトは小さくし、ユーザー固有のデータのみが含まれるようにします。JWT を作成する前に、できる限りのデータをオブジェクトのクラスに保存してください。上限を超える大きなオブジェクトについては、REST API を使用してオブジェクトを作成し、オブジェクト ID のみを JWT で送信するようにしてください。
3. [Google Pay に保存] ボタンを追加する
[Google Pay に保存] ボタンを表示するページに次のスクリプトを挿入します。
<script src="https://apis.google.com/js/platform.js" type="text/javascript"></script>
次に、[Google Pay に保存] ボタンの配置と属性を定義する g:savetoandroidpay 名前空間タグを挿入します。以前に生成した JWT を挿入します。
<g:savetoandroidpay jwt="{jwt_generated}" onsuccess="successHandler"
onfailure="failureHandler" size="small" theme="light" ></g:savetoandroidpay>
これで、[Google Pay に保存] ボタンがウェブページに表示されます。
JavaScript ウェブボタンの詳細については、Google Pay API for Passes for Web API リファレンスのドキュメントをご覧ください。
