Google ReLaunches Google Pay API for Passes as Google Wallet API with Support for Generic Passeshttps://developers.googleblog.com
Formerly known as Google Pay API for Passes, the Google Wallet API lets you digitize everything from boarding passes to loyalty programs, and engage your customers with notifications and real-time updates.
The Google Pay API for Passes supported 7 types of passes: offers, loyalty cards, gift cards, event tickets, boarding passes, transit tickets and vaccine cards. The new version also supports generic passes on the Google Wallet API so you can customize your pass objects to adapt to your program characteristics.
This can be great if you do events.
