เพิ่มบัตรหลายประเภท

คุณสามารถเพิ่มบัตรหลายใบลงในบัญชี Google Wallet ของผู้ใช้ได้ในกรณีต่อไปนี้ คลิกปุ่ม "เพิ่มลงใน Google Wallet" บัตรแต่ละใบที่เพิ่มสามารถ บัตรประเภทอื่น (ยกเว้นการ์ดยืนยันการฉีดวัคซีนและผลตรวจเชื้อ) สำหรับ เช่น สามารถเพิ่มตั๋วเข้างานและข้อเสนอใน JWT ที่ระบุ ดังที่แสดงด้านล่าง

{
  "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": []
}

เมื่อผู้ใช้คลิกลิงก์ ก็จะเห็นจำนวนบัตรที่บันทึกไว้ ขณะเพิ่มบัตรลงในอุปกรณ์ หลังจากเพิ่มบัตรแล้ว คุณจะทำสิ่งต่อไปนี้ได้ ที่พบในกระเป๋าสตางค์
