Getting started tutorials
Ready to create and issue your first pass? Check out the Google Wallet API getting started tutorials that walk you through the whole development process from start to finish using your choice of the Google Wallet REST API or Google Wallet Android SDK.
Self-guided codelabs walk you through the necessary steps to add a pass to Google Wallet. To get started, choose "Android" if your implementation will be on Android devices only and choose "Web" if your implementation supports Android, Web, Email or SMS.
The Pass Builder is an interactive tool that lets you customize and preview a basic pass. All you have to do is fill in the form fields and the Pass Builder will output the Passes Class and Passes Object definitions you can use to create an actual pass.
Pass Builder doesn't support all customizable pass fields, but is a great way to get started and familiarize yourself with some of the most common pass customizations. For a complete list of pass fields, see the reference documentation.
