Se um usuário comprar vários ingressos de eventos, é útil permitir que ele adicione todos os ingressos para o dispositivo de uma só vez. É possível definir vários objetos ou classes em um JSON Web Token (JWT), que pode ser usado para criar uma Botão ou link Adicionar à Carteira do Google. Quando o usuário clica no botão, ele vai adicionar todos os cartões definidos ao dispositivo do usuário ao mesmo tempo.
No JWT a ser assinado, inclua classes e objetos de passagem no
As matrizes eventTicketClasses e eventTicketObjects da propriedade payload,
respectivamente. Confira nos exemplos a seguir duas maneiras de fazer isso.
Para mais informações sobre a representação da interface de vários cartões, consulte Agrupar vários ingressos de eventos.
Classes e objetos atuais
Este exemplo usa classes e objetos pré-criados e requer apenas os IDs dos
cada um. A propriedade classId é opcional para os objetos do cartão. É
mostrados aqui para fins demonstrativos.

Criar novas classes e objetos
Esse exemplo define uma classe e vários objetos filhos. Tanto a classe quanto Os objetos são criados pela Carteira do Google somente quando o usuário clica nos Adicionar à Carteira do Google e adicionar os cartões ao dispositivo.
