使用 Google Wallet API 快速取得優惠。Google Wallet API 可讓客戶輕鬆將優惠新增至手機上的 Google 錢包，在適當時機輕鬆存取。
將優惠儲存在 Google 錢包中，可讓使用者更有效率地兌換優惠、保持井然有序，並加快存取速度。如要找出已儲存的優惠，使用者必須開啟 Google 錢包應用程式，向上滑動並輕觸想要使用的項目。將優惠儲存在 Google 錢包中，方便使用者查看所有適用的優惠。
透過優惠，您也可以在到期的兩天前傳送通知給使用者。這有助於確保高意願使用者在到期前兌換優惠。
您可以透過 Google Wallet API，為使用者核發票證，以便儲存在多個平台 (包括 Android 應用程式) 和任何支援超連結的地方，例如網站、電子郵件和簡訊。
API 與 SDK
Google Wallet API 提供 REST API 和 Android SDK，能協助您輕鬆快速地核發及管理票證。
注意：透過 Google Wallet API 核發票證不需要使用 Google Wallet REST API 或 Google Wallet Android SDK，但強烈建議使用。如要進一步瞭解如何在不使用 REST API 或 Android SDK 的情況下核發票證，請參閱在 JWT 中建立票證物件和票證類別一文。
需求條件
如要透過 Google Wallet API 核發票證，請先按照下列步驟操作：

The Google Wallet API\nmakes it straightforward for your customers to add offers to Google Wallet\non their phones, providing easy access at the right time.\n\nSaving offers in Google Wallet lets your users redeem them more\nefficiently, eliminates clutter, and enables faster\naccess. To find a saved offer, users need to open up the Google Wallet app,\nswipe up, and tap the one they want to use. By saving offers in\nGoogle Wallet, users can see all of their available offers.\n\nWith offers, you can also [send notifications](/wallet/retail/offers/use-cases/offer-expiration-notification)\nto your users two days before they expire. This helps make sure that high intent\nusers redeem their offers before the expiry.\n\nSupported platforms\n-------------------\n\nWith the Google Wallet API, you can issue passes for your users to save in their Google Wallet across multiple platforms, including Android apps, and anywhere hyperlinks are supported, such as websites, email, and SMS messages.\n\n### APIs \\& SDKs\n\nThe Google Wallet API offers a REST API and an Android SDK to help you issue and manage your passes quickly and easily.\n\n- [Google Wallet REST API](/wallet/retail/offers/web/prerequisites) \n\n To issue passes on platforms such as the Web, email, or SMS, we recommend you use the Google Wallet REST API. The API provides a set of endpoints that let you create, retrieve, and update the various components of passes.\n- [Google Wallet Android SDK](/wallet/retail/offers/android/prerequisites) \n\n To issue passes in an Android app, we recommend you use the Google Wallet Android SDK. The SDK provides a variety of convenience methods that make it easy to integrate the Google Wallet API into your mobile apps using native code.\n\nNote: Using the Google Wallet REST API or Google Wallet Android SDK is not required to issue passes with the Google Wallet API, but are strongly recommended. For more information on issuing passes without using the REST API or Android SDK, see [Creating Passes Objects and Passes Classes in the JWT](https://developers.google.com/wallet/retail/offers/overview/add-to-google-wallet-flow#creating-passes-objects-and-passes-classes-in-the-jwt).\n\nRequirements\n------------\n\nTo issue passes with the Google Wallet API, you will first need to do the following:\n\n- Create a [Google Wallet API Issuer account](/wallet/retail/offers/getting-started/issuer-onboarding).\n- Non-Android developers: Create a [Google Cloud account](https://console.cloud.google.com/freetrial).\n- Android developers: [Set up Google Play services.](/android/guides/setup)\n\nGetting started with the Google Wallet API\n------------------------------------------\n\nBefore you start working with the Google Wallet API, take a look at these useful articles that will familiarize you with the basic features and terminology.\n\n- [Key concepts and terminology](/wallet/retail/offers/resources/terminology): This article will familiarize you with all the important terms and features you will need to work with the Google Wallet API.\n- [Passes Classes and Objects overview](/wallet/retail/offers/overview/how-classes-objects-work): Passes that you issue to your users are created by combining a Passes Class with a Passes Objects. This article will familiarize you with both of these concepts, and how they are used to create passes.\n- [Google Wallet pass development flow](/wallet/retail/offers/overview/add-to-google-wallet-flow): This article provides an end-to-end overview of all of the steps needed to create a pass with the Google Wallet API from start to finish.\n\n### Tools \\& resources\n\n- **Codelabs** \n\n\n Self-guided codelabs walk you through the necessary steps to add a pass\n to Google Wallet. To get started, choose \"Android\" if your implementation will be on Android devices\n only and choose \"Web\" if your implementation supports Android, Web, Email or SMS.\n\n\n [Android](https://g.co/wallet/android-codelab)\n [Web](https://g.co/wallet/web-codelab)\n- **Pass builder** \n\n Build your first pass visually with the [pass builder](/wallet/retail/offers/resources/pass-builder) tool, and automatically generate the JSON you need to create the pass with the Google Wallet API.\n- **Google Wallet Github**\n\n Get helpful tools, libraries and sample code for a variety of programming languages in the [Google Wallet Github org](https://github.com/google-wallet)."]]
