Google Pay API for Passes is now called Google Wallet API
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.
New features in Google Wallet API
Support for Generic Pass Type
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. But what if you want to issue passes or cards that do not fit into any of these categories, such as membership cards, or insurance cards?
We are thrilled to announce support for generic passes to the Google Wallet API so you can customize your pass objects to adapt to your program characteristics. The options are endless. If it is a card and has some text, a barcode or a QR code, it can be saved as a generic card.
You now have the flexibility to control the look and design of the card itself, by providing a card template that can contain up to 3 rows with 1-3 fields per row. You can also configure a number of attributes such as the barcode, QR code, or a hero image. Check out our documentation to learn more about how to create generic passes.
While generic passes can be used to mimic the appearance of any existing supported pass type (such as a loyalty card), we recommend you to continue to use specialized pass types when available. For example, when you use the boarding pass type for boarding passes your users receive flight delay notifications.
Grouping passes and mixing pass types
With the new Google Wallet API, you can also group passes to offer a better experience to your users when multiple passes are needed. For example, you can group the entry ticket, a parking pass, and food vouchers for a concert.
In your user’s list of passes, your users see a pass tile with a badge showing the number of items in the group. When they tap on this tile, a carousel with all passes appears, allowing them to easily swipe between all passes in the group.
Here is an example JSON Web Token payload showing one offer and one event ticket, mixed together and sharing the same groupingId. Later, if you need to add or remove passes to/from the group, you can use the REST API to update the grouping information.
A note about Google Pay API for Passes:
Although we are introducing the Google Wallet API, all existing developer integrations with the previous Google Pay Passes API will continue to work. When the Google Wallet app is launched in just a few weeks, make sure to use the new “Add to Google Wallet” button in the updated button guidelines.
