Google Pay にパスを保存する

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。

  1. オブジェクトを拡張する Class を定義する。
  2. Object を表す JWT を生成する。
  3. [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。

OAuth 2.0 サービス アカウントの秘密鍵を使用して、LoyaltyObject を JWT にエンコードします。次のスニペットは、JWT をさまざまな言語でエンコードする方法を示しています。プロトコルタブにはエンコードされていない JWT が示されています。JWT のフィールドの説明については、Google Pay API for Passes JWT をご覧ください。

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。
