There are multiple ways which allow you to administrate and set up your vehicles.
Vehicle Management API⚓︎
Manage all of your fleet’s vehicles: Get a list of all your vehicles, manage master data such as license plate, VIN, tags and custom fields, see the equipped telematics unit, and get the latest vehicle state.
Vehicle Lifecycle API⚓︎
The Vehicle Lifecycle API allows you to add vehicles to your fleet. The use of this API is optional and only recommended if you would like to add vehicles to your OneAPI fleet from within your own application. Usually, the “adding vehicle assistant” within FleetControl is the easier option to quickly add one or multiple vehicles to your fleet.
