Antes de começar a usar a API Web, verifique se você cumpre os pré-requisitos. Para continuar com a API Web, você precisa ter uma conta de serviço e uma chave de conta de serviço, além de conceder acesso à conta de serviço para chamar a API Google Wallet.
Faça o download do exemplo de código no GitHub para executar os snippets de código mencionados nas etapas abaixo.
Autenticação e autorização
As solicitações à API Google Wallet precisam ser autenticadas para que a API possa identificar que uma solicitação está sendo feita pelo seu aplicativo. Para conseguir um token de acesso, a chave da conta de serviço é usada.
Primeiro, faça as importações de biblioteca necessárias e defina algumas variáveis para o JSON da conta de serviço e os IDs do emissor, da classe, do usuário único e do objeto que serão salvos.

Como criar um objeto de cartões
Um objeto de cartões é uma instância de uma classe de cartões. Para criar um objeto de cartões, você precisa fornecer os seguintes atributos:
classId: oidda classe de cartõesid: um ID exclusivo para representar o vale-presente do cliente
Consulte as diretrizes do modelo para mais informações sobre como esses atributos são representados no cartão.
Exemplo de código para criar um objeto de cartões:
Java
/**

*
* @param issuerId The issuer ID being used for this request.

Depois de concluído, o objeto de cartões do cliente será criado no servidor. No entanto, nesta etapa, o objeto de cartões não está vinculado a um usuário do Google ou ao dispositivo dele. Para que o cartão seja associado a um usuário da Carteira do Google, o usuário precisa primeiro adicionar o cartão à Carteira do Google.
Como adicionar à Carteira do Google
A adição de um cartão à Carteira do Google vincula o objeto de cartões a um usuário do Google e só pode ser iniciada no contexto de uma identidade do Google conectada. Para fazer isso, direcione o usuário a um URL de "Adicionar à Carteira do Google".
O URL "Adicionar à Carteira do Google" é gerado de maneira dinâmica e contém as seguintes informações sobre o ID do objeto de cartões criado na etapa anterior. Essas informações são codificadas como um JSON Web Token (JWT).
JSON Web Token (JWT)
O JWT tem declarações que você (o emissor) está fazendo sobre o objeto de cartões que vai ser salvo pelo usuário. O JWT precisa ser assinado com o uso da private_key da chave da conta de serviço conseguida na etapa Criar conta de serviço, e o Google vai validar essas declarações verificando a assinatura JWT.
As declarações JWT precisam ter a seguinte estrutura:
{
"aud": "google",

Depois de receber um JWT assinado, use essas informações para criar um link Adicionar à Carteira do Google.
Link "Adicionar à Carteira do Google"
O link "Adicionar à Carteira do Google" tem este formato:
https://pay.google.com/gp/v/save/{token}
Esse link pode ser incorporado à sua página da Web ou enviado por e-mail como um hiperlink. Ele também pode ser enviado ao cliente usando outros canais, como chat e SMS.
O comprimento seguro de um JWT codificado é 1.800 caracteres. Se o JWT estiver abaixo desse limite, o objeto inteiro poderá ser incluído no JWT assinado. Os JWTs precisam ficar abaixo desse limite. Se o comprimento for superior a 1.800 caracteres, talvez a ação de salvar não dê certo devido ao truncamento dos navegadores da Web.
Botão "Adicionar à Carteira do Google"
Para ter resultados melhores, use os recursos do botão Carteira do Google na sua página da Web, e-mail ou app Android.
O botão "Carteira do Google" pode ser renderizado de duas maneiras:
- O botão JavaScript Web pode ser usado para sites.
- O link do JWT com um botão pode ser usado para e-mail, SMS, apps e sites.
[SOMENTE TESTE] cartões
No modo de demonstração, todos os cartões criados terão um texto adicional "[SOMENTE TESTE]" no título. Isso serve para diferenciar os cartões de demonstração dos ativos. Depois de receber da nossa equipe a aprovação para a produção, esses cartões do modo de demonstração não terão mais o texto adicional quando o usuário reabrir o app da carteira em um dispositivo conectado.
Próximas etapas
- Personalizar a aparência do cartão
- Testar a integração e começar a usar!
