Add links to your Gift card

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

• Use GiftCardClass.LinksModuleData to add links to all gift cards that are associated with the GiftCardClass.
• Use GiftCardObject.LinksModuleData to add a link to a specific gift card GiftCardObject.
• Use GiftCardObject.appLinkData to place an app link at the bottom of that particular Pass.
• Use GiftCardClass.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.

Feature example

Issuer

Set the app link on your Google Wallet pass

For a given gift card, set the field GiftCardObject.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.

Note: To deep link to a specific view within an app you must use webAppLinkInfo.

  {
    "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"
        }
      }
    }
  }
}
