Add links to your Loyalty card

There are four ways to add links to a loyalty card.

• Use LoyaltyClass.LinksModuleData to add links to all loyalty cards that are associated with the LoyaltyClass.
• Use LoyaltyObject.LinksModuleData to add a link to a specific loyalty card LoyaltyObject.
• Use LoyaltyObject.appLinkData to place an app link at the bottom of that particular Pass.
• Use LoyaltyClass.appLinkData to place an app link at the bottom of all the passes of that class.

One benefit of app linking is that it empowers your call-to-action to navigate users to your branded experiences from Google Wallet. Links with this feature appear at the bottom of the Pass.
