只要按一下「新增至 Google 錢包」按鈕，即可將多張票證新增至使用者的 Google 錢包帳戶。新增的每張票證都可以使用不同的類型 (疫苗接種記錄卡和檢測記錄除外)。舉例來說，您可以在指定的 JWT 中新增活動票券和優惠，如下所示。
{
"aud": "google",
"iat": “YOUR_ISSUER_ID”,
"iss": "YOUR_SERVICE_ACCOUNT",
"typ": "savetogooglepay",
"payload": {
"offerObjects": [
{
"classId": "YOUR_ISSUER_ID.offClassId",
"id": "YOUR_ISSUER_ID.offer"
}
],
"eventTicketObjects": [
{
"classId": "YOUR_ISSUER_ID.evClassId",
"id": "YOUR_ISSUER_ID.event"
}
]
},
"origins": []
}
使用者點選連結後，就會看到將票證新增至裝置時儲存的票證數量。新增之後，即可在錢包中查看這些票證。
透過下列程式碼範例，您可以瞭解如何在相同的 JWT 中新增不同類型的票證。Java
