Links with this feature appear at the bottom\nof the Pass.\n\n### Feature example\n\n|--------|\n| |\n| Issuer |\n\n### Set the app link on your Google Wallet pass\n\nFor a given transit pass, set the field `TransitObject.appLinkData`\nto the URI or Package name of your app or website.\n\n\nSee the format and context of the `appLinkData` field in the following source code:\nThe `displayText` field is limited to 30 characters.\n**Note:** To deep link to a specific view within an app you must use webAppLinkInfo. \n\n```\n {\n \"id\": string,\n \"classId\": string,\n …\n …\n …\n \"appLinkData\": {\n \"androidAppLinkInfo\": {\n \"appTarget\": {\n \"packageName\": \"com.google.android.gm\",\n }\n },\n \"webAppLinkInfo\": {\n \"appTarget\": {\n \"targetUri\": {\n \"uri\": \"https://mail.google.com/mail/\",\n \"description\": \"Web link for Gmail\"\n }\n }\n }\n \"displayText\": {\n \"defaultValue\": {\n \"value\": \"Our awesome app!\"\n }\n }\n }\n }\n```\nFor posterity the following implementation will also work. \n\n```\n{\n \"id\": string,\n \"classId\": string,\n …\n …\n …\n \"appLinkData\": {\n \"androidAppLinkInfo\": {\n \"appTarget\": {\n \"targetUri\": {\n \"uri\": \"https://play.google.com/store/apps/details?id=com.google.android.gm\",\n \"description\": \"Play store link for Gmail app\"\n }\n }\n }\n }\n}\n```"]]
