Google has put out a new Google Developers Live video on YouTube discussing the Wallet Objects API and how to get started with their Java quick start sample. This is designed to help developers get started with their integration quickly.
It showcases authorizing access, inserting a new Wallet Objects class, using the Saved Wallet API and using the web service API to enable instant sign-up and linking from the Google Wallet app.
When Google launched the new Wallet app last month, it announced some new loyalty programs, which take advantage of the Objects API, which itself, was launched earlier this year.
