Use o método ListVehicles para encontrar todos os veículos que atendem a algumas opções de solicitação específicas. O método ListVehicles retorna uma lista paginada de veículos
no projeto que corresponde a consultas em campos de veículos.
Filtrar por atributos do veículo
Você também pode usar esse método para filtrar atributos de veículos, que atuam como operador AND
quando usados em conjunto com outras especificações de campo. Para detalhes
sobre a sintaxe de consulta de filtro, consulte Filtragem: AIP-160
para exemplos. Para detalhes sobre como criar atributos de veículo, consulte o Campo de atributos do veículo no guia Atualizar campos do veículo.
Exemplo de lista de veículos
Este exemplo filtra os campos vehicle_type e attributes usando a string filter, mostrando apenas veículos do tipo AUTO e obtendo o valor LUXURY para o atributo personalizado class.
