Se un utente acquista più biglietti per eventi, è utile consentire all'utente di aggiungere tutti i biglietti per il dispositivo in una sola volta. Puoi definire più oggetti o classi in un token JWT (JSON Web Token), che può essere utilizzato per creare Pulsante o link Aggiungi a Google Wallet. Quando l'utente fa clic sul pulsante, aggiungerà contemporaneamente tutte le tessere definite al dispositivo dell'utente.
Nel JWT da firmare, includi le classi di superamento e gli oggetti nella
Array eventTicketClasses e eventTicketObjects della proprietà payload,
rispettivamente. I seguenti esempi mostrano due varianti relative a questa operazione.
Per maggiori informazioni sulla rappresentazione UI di più tessere, consulta Raggruppare più biglietti per eventi.
Classi e oggetti esistenti
Questo esempio utilizza classi e oggetti creati in precedenza e richiede solo gli ID di
ciascuna. Tieni presente che la proprietà classId è facoltativa per gli oggetti pass. È
mostrati qui a scopo dimostrativo.
