Bibliotecas de cliente

Nossas bibliotecas de cliente oferecem visualizações de alto nível e elementos básicos da funcionalidade da Google Ads API, facilitando o desenvolvimento rápido de apps. Recomendamos começar com uma para quem não conhece a API.

Versões da API compatíveis

A tabela abaixo lista as versões de biblioteca específicas compatíveis com cada versão da API disponível.

Configuração

Cada biblioteca de cliente da API Ads fornece diferentes configurações e métodos de carregamento que podem ser usados para personalizar o comportamento.

Veja as variáveis de ambiente que são comuns a todas as bibliotecas de cliente e que podem ser carregadas para definir as configurações:

• Biblioteca de cliente
  • GOOGLE_ADS_CONFIGURATION_FILE_PATH: caminho para o arquivo de configuração.
• OAuth2
  • Modo de aplicativo
    • GOOGLE_ADS_CLIENT_ID : defina esse valor como seu ID do cliente OAuth2.
    • GOOGLE_ADS_CLIENT_SECRET : defina esse valor como a chave secreta do cliente OAuth2.
    • GOOGLE_ADS_REFRESH_TOKEN : defina esse valor como um token de atualização OAuth2 pré-gerado, caso queira reutilizar tokens OAuth2. Esta configuração é opcional.
  • Modo da conta de serviço
    • GOOGLE_ADS_JSON_KEY_FILE_PATH : defina esse valor como o caminho do arquivo de configuração JSON do OAuth2.
    • GOOGLE_ADS_IMPERSONATED_EMAIL : defina esse valor como o endereço de e-mail da conta que você representa.
• API Google Ads
  • GOOGLE_ADS_DEVELOPER_TOKEN : defina como o token de desenvolvedor.
  • GOOGLE_ADS_LOGIN_CUSTOMER_ID : é o ID do cliente autorizado a ser usado na solicitação, sem hifens (-).
  • GOOGLE_ADS_LINKED_CUSTOMER_ID : esse cabeçalho só é necessário para métodos que atualizam os recursos de uma entidade quando autorizados por meio de contas vinculadas na IU do Google Ads (recurso AccountLink na API Google Ads). Defina esse valor como o ID de cliente do provedor de dados que atualiza os recursos do ID de cliente especificado. Ele precisa ser definido sem hifens (-). Para saber mais sobre contas vinculadas, acesse a Central de Ajuda.

As variáveis de ambiente geralmente são definidas em um arquivo de configuração bash, como um arquivo .bashrc ou .bash_profile localizado no diretório $HOME. Eles também podem ser definidos usando a linha de comando.

Veja a seguir algumas etapas básicas para definir uma variável de ambiente usando um arquivo .bashrc com um terminal:

# Append the line "export GOOGLE_ADS_CLIENT_ID=1234567890" to
# the bottom of your .bashrc file.
echo "export GOOGLE_ADS_CLIENT_ID=1234567890" >> ~/.bashrc

# Update your bash environment to use the most recently updated
# version of your .bashrc file.
src ~/.bashrc

As variáveis de ambiente também podem ser definidas na instância de terminal diretamente da linha de comando:

export GOOGLE_ADS_CLIENT_ID=1234567890

Outra alternativa é definir variáveis de ambiente ao chamar o comando que as utiliza:

GOOGLE_ADS_CLIENT_ID=1234567890 php /path/to/script/that/uses/envvar.php

Paginação de pesquisa

O GoogleAdsService.Search normalmente é usado em apps interativos que mostram páginas de resultados.

Nossa biblioteca de cliente implementa automaticamente a paginação quando você itera os resultados para que você possa fazer o download e processar todos eles de uma só vez em sequência. Por exemplo:

private void runExample(GoogleAdsClient googleAdsClient, long customerId, long labelId) {
  try (GoogleAdsServiceClient googleAdsServiceClient =
      googleAdsClient.getLatestVersion().createGoogleAdsServiceClient()) {
    // Creates a request that will retrieve all campaign labels with the specified
    // labelId using pages of the specified page size.
    SearchGoogleAdsRequest request =
        SearchGoogleAdsRequest.newBuilder()
            .setCustomerId(Long.toString(customerId))
            .setPageSize(PAGE_SIZE)
            .setQuery(
                "SELECT campaign.id, campaign.name, label.id, label.name "
                    + "FROM campaign_label WHERE label.id = "
                    + labelId
                    + " ORDER BY campaign.id")
            .build();
    // Issues the search request.
    SearchPagedResponse searchPagedResponse = googleAdsServiceClient.search(request);
    // Checks if the total results count is greater than 0.
    if (searchPagedResponse.getPage().getResponse().getTotalResultsCount() > 0) {
      // Iterates over all rows in all pages and prints the requested field values for the
      // campaigns and labels in each row. The results include the campaign and label
      // objects because these were included in the search criteria.
      for (GoogleAdsRow googleAdsRow : searchPagedResponse.iterateAll()) {
        System.out.printf(
            "Campaign found with name '%s', ID %d, and label: %s.%n",
            googleAdsRow.getCampaign().getName(),
            googleAdsRow.getCampaign().getId(),
            googleAdsRow.getLabel().getName());
      }
    } else {
      System.out.println("No campaigns were found.");
    }
  }
}

Dependendo do caso de uso, pode ser necessário:

• Otimize quantas páginas são buscadas.
• Otimize a quantidade de resultados armazenados de uma só vez.
• Faça o download e processe as páginas de resultados em uma ordem específica.

Isso pode ser feito armazenando os tokens de página em vez dos resultados, o que aumenta a complexidade do seu código.
