Add link to an Offer

There are four ways to add links to a offer.

• Use OfferClass.LinksModuleData to add links to all offers that are associated with the OfferClass.
• Use OfferObject.LinksModuleData to add a link to a specific offer OfferObject.
• Use OfferObject.appLinkData to place an app link at the bottom of that particular Pass.
• Use OfferClass.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 offer, set the field OfferObject.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"
        }
      }
    }
  }
}
