Add links to your Generic Pass

There are four ways to add links to a Generic pass.

• Use GenericClass.LinksModuleData to add links to all Generic passes that are associated with the GenericClass.
• Use GenericObject.LinksModuleData to add a link to a specific Generic pass GenericObject.
• Use GenericObject.appLinkData to place an app link at the bottom of that particular Pass.
• Use GenericClass.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.

Set the app link on your Google Wallet pass

For a given Generic pass, set the field GenericObject.appLinkData to the URI or Package name of your app or website.

See the format and context of the appLinkData field in the following source code: The displayText field is limited to 30 characters.

  {
    "id": string,
    "classId": string,
    …
    …
    …
    "appLinkData": {
      "androidAppLinkInfo": {
        "appTarget": {
          "packageName": "com.google.android.gm",
        }
      },
      "webAppLinkInfo": {
        "appTarget": {
           "targetUri": {
              "uri": "https://mail.google.com/mail/",
              "description": "Web link for Gmail"
           }
        }
      }
      "displayText": {
        "defaultValue": {
           "value": "Our awesome app!"
        }
      }
    }
  }

For posterity the following implementation will also work.

{
  "id": string,
  "classId": string,
  …
  …
  …
  "appLinkData": {
    "androidAppLinkInfo": {
      "appTarget": {
        "targetUri": {
          "uri": "https://play.google.com/store/apps/details?id=com.google.android.gm",
            "description": "Play store link for Gmail app"
        }
      }
    }
  }
}
