To create a Google Wallet pass, start by signing up as a pass issuer in the Google Pay & Wallet Console. Next you set up a pass class, which is the shared design for one kind of pass, such as your loyalty program or an event. Each customer then gets a pass object with their own details, like their name or points. Most businesses build this with the Google Wallet API, which needs a developer, or use a pass-making service that handles it for them. Customers save the pass from a link or an “Add to Google Wallet” button. One thing trips people up. New issuer accounts start in demo mode, and every pass shows a “TEST ONLY” label until Google reviews the account and approves it for publishing.
