Jika pengguna membeli beberapa tiket acara, sebaiknya izinkan pengguna semua tiket ke perangkat mereka sekaligus. Anda dapat menentukan beberapa objek atau class dalam JSON Web Token (JWT), yang kemudian dapat digunakan untuk membuat Tombol atau link Tambahkan ke Google Wallet. Ketika pengguna mengeklik tombol, akan menambahkan semua kartu yang ditentukan ke perangkat pengguna secara bersamaan.
Dalam JWT yang akan ditandatangani, sertakan kelas pass dan objek dalam
Array eventTicketClasses
dan eventTicketObjects
dari properti payload
,
secara berurutan. Contoh berikut menunjukkan dua variasi tentang cara melakukannya.
Untuk informasi selengkapnya tentang representasi UI dari beberapa kartu, lihat Mengelompokkan beberapa tiket Acara.
Class dan objek yang sudah ada
Contoh ini menggunakan class dan objek yang telah dibuat sebelumnya dan hanya memerlukan ID
masing-masing. Perhatikan bahwa properti classId
bersifat opsional untuk objek kartu. Penting
yang ditampilkan di sini untuk tujuan demo.

}
Membuat class dan objek baru
Contoh ini menentukan sebuah class dan beberapa objek turunan. Baik kelas maupun objek dibuat oleh Google Wallet hanya saat pengguna mengklik Link Tambahkan ke Google Wallet dan tambahkan kartu ke perangkat mereka.
