Any user of HERE Tracking must be a member of a Tracking project. Tracking projects are created through admin.tracking.here.com. A project is the overall group through which billing and user management is done. Projects group devices and resources, to which multiple users can be granted access. Access to the resources within the project can be limited by assigning different roles to the members. A Project Admin is a user who has access to all resources in the project.
Some HERE Tracking APIs scope requests to a project. For example, when listing geofences, we need to know which project's geofences should be listed. HERE Tracking can implicitly resolve the project id if the user calling the API is a member of a single project. However, if the user is a member of multiple projects, the request must be provided
projectId query parameter.
