For server-to-server (trusted) communication, we recommend using language-specific GAPI client libraries for a better experience than developing over raw REST or gRPC. The protobuf files these clients are based on are publicly available at https://github.com/googleapis/googleapis/tree/master/google/maps/fleetengine/v1.
If libraries do not exist in your application's language, we recommend using gRPC or the Fleet Engine REST endpoints.
NOTE: GAPIC libraries are meant to be run in trusted (server) environments.
JWTs are unnecessary. Use Application Default Credentials along with the
appropriate ondemandAdmin
role.
Java
Java libraries are published under google.maps.fleetengine.v1

You can utilize the Fleet Engine Auth Library for Java to create signed JSON web tokens within the Java environment.
You can view Java examples for interacting with the Fleet Engine API on the Getting started with Fleet Engine page.
