The Google Wallet API makes it easy for your customers to add transit passes with QR codes and barcodes to Google Wallet on their phones.
With 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.
APIs & SDKs
The Google Wallet API offers a REST API and an Android SDK to help you issue and manage your passes quickly and easily.
- Google Wallet REST API
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.
- Google Wallet Android SDK
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.
Note: 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.
RequirementsTo issue passes with the Google Wallet API, you will first need to do the following:
- Create a Google Wallet API Issuer account.
- Non-Android developers: Create a Google Cloud account.
- Android developers: Set up Google Play services.
