PUT Vehicle - C#

The PUT Vehicle method within the Customer Meta Data – Vehicles API enables integrated users to edit the vehicle object details within the referenced REVEAL account.

Before attempting to retrieve vehicle location information it is important to know if the REVEAL account has been updated with valid VEHICLE NUMBERS for each vehicle to be pulled via the API. The VEHICLE NUMBER and VEHICLE NAME fields are different fields within REVEAL and the VEHICLE NUMBER field is not automatically populated upon account creation.

Main Method

namespace Rest_Put_Vehicle_Example
class Program
static void Main()
// Token call goes here, see Rest_Token_Example

// App Id from Fleetmatics Integration Manager (FIM)
string appId = "companyname-p-us-4654sdf4fa351af65dsf1d";

// Put Vehicle URI
string putVehicleUri = "https://fim.api.ENV.fleetmatics.com/cmd/v1/vehicles/";

// Local variables that correspond to put body fields
string vehicleNum = "0112358";
string vehicleName = "TESTER";
string registrationNumber = "GA23423";
string vin = "1GNDX03E5YD117167";
string make = "Ford";
string model = "F150";
int? year = 2012;
double? tankCapacity = 20.5;
double? highwayMPG = 14.5;
double? cityMPG = 11.5;
int? vehicleSize = 1;

// Create new PUT_Vehicle object
var rest_put = new PUT_Vehicle();

// Pass in local variables to create a vehicle object
rest_put.CreateNewPutVehicle(vehicleName, vehicleNum, registrationNumber, vin, make, model, year, tankCapacity, highwayMPG, cityMPG, vehicleSize);

// Call method to execute the API call
rest_put.PutVehicle(/* token object or auth string passed here */, putVehicleUri, appId);
