There are three ways to add links to a loyalty card.
- Use
LoyaltyClass.LinksModuleData
to add links to all loyalty cards that are associated with theLoyaltyClass
. - Use
LoyaltyObject.LinksModuleData
to add a link to a specific loyalty cardLoyaltyObject
. - Request access to app linking, and then use
LoyaltyObject.appLinkData
to place an app link on top of Pass Details.
One benefit of app linking is that it empowers your call-to-action channel to navigate users to your branded experiences from Google Wallet. Links with this feature appear on top of Pass Details, and can be embedded in a logo, description, or call-to-action word.

Request access to app linking
Request access with the Contact Support button in Google Pay and Wallet Console. Select Google Wallet API as the topic first, and then choose App linking as the support type.
Set the app link on your Google Wallet pass
For a given loyalty card, set the field LoyaltyObject.appLinkData
to the URI of your app or website. The URI can be any format, but we recommend that you use a
dynamic link.
See the format and context of the appLinkData
field in the following source code:
{ "id": string, "classId": string, … … … "appLinkData": { "androidAppLinkInfo": { "appLogoImage": { "sourceUri": { "uri": string } }, "title": { "defaultValue": { "language": string, "value": string } }, "description": { "defaultValue": { "language": string, "value": string } }, "appTarget": { "targetUri": { "uri": string, "description": string } } } } … … … }
