I'm working in .net and can retrieve the DutyStatusAvailability records and combine them with Users to associate the HOS data with drivers in our TMS. I looked at the data I'm getting back in this and could just be missing it, but is there a way in the API to retrieve which vehicle a driver is assigned to? We would like to update the truck number the driver is assigned to in our TMS and pass that truck number on to the customer's fuel card provider so that it always stays in sync with the truck the driver is currently in.
