Bibliotecas de cliente GAPI

Para a comunicação de servidor para servidor (confiável), recomendamos o uso de bibliotecas de cliente da GAPI específicas da linguagem para uma experiência melhor do que o desenvolvimento por meio de REST ou gRPC brutos. Os arquivos protobuf em que esses clientes se baseiam estão disponíveis publicamente em https://github.com/googleapis/googleapis/tree/master/google/maps/fleetengine/v1.

Se não houver bibliotecas na linguagem do seu aplicativo, recomendamos o uso do gRPC ou dos endpoints Fleet Engine REST.

OBSERVAÇÃO: as bibliotecas GAPIC devem ser executadas em ambientes confiáveis (servidor). JWTs são desnecessários. Use o Application Default Credentials com o papel ondemandAdmin apropriado.

Java

As bibliotecas Java são publicadas em google.maps.fleetengine.v1.

npm

É possível especificar o URL da biblioteca na seção dependencies de package.json:

{
  "dependencies": {
    "@googlemaps/fleetengine": "https://storage.googleapis.com/fleetengine-gapic/dist/latest_release/maps-fleetengine-v1-nodejs.tar.gz",
