Update Vehicle

Update specific fields of an existing vehicle. All fields are optional - only include fields you want to modify. Omitted fields will retain their current values.

CO2e Recalculation: When you update fields like vehicle_fuel_id, registration_year, or market_segment, CO2e emissions are automatically recalculated.

Common Errors

401 Unauthorized

Cause: Missing or invalid API key

{
  "detail": "Invalid API key",
  "code": "INVALID_API_KEY"
}

Solution: Verify your API key is valid and active. Get a new one from Settings → API.

404 Not Found

Cause: Vehicle not found in organization

{
  "code": "VEHICLE_NOT_FOUND",
  "detail": "Vehicle with id=UUID('...') not found"
}

Solution: Verify that the vehicle ID is correct and belongs to your organization. Use the List Vehicles endpoint to get valid IDs.

422 Validation Error

Cause: Invalid values for enumerated fields

{
  "detail": [
    {
      "loc": ["body", "type"],
      "msg": "value is not a valid enumeration member; permitted: 'passenger', 'freight'",
      "type": "type_error.enum"
    }
  ]
}

Solution: Ensure enum values are exactly as specified. Use valid country codes (2-3 characters) and permitted values for type, ownership, market_segment, and size.

Use Cases

Update Vehicle Ownership Status

Change vehicle ownership from owned to rented:

def change_vehicle_ownership(vehicle_id, new_ownership):
    """Update vehicle ownership status"""
    payload = {"ownership": new_ownership}

    response = requests.patch(
        f"https://api.dcycle.io/v1/vehicles/{vehicle_id}",
        headers=headers,
        json=payload

    return response.json()

# Change to rented
updated = change_vehicle_ownership(
    "550e8400-e29b-41d4-a716-446655440000",
    "rented"
)
print(f"Updated: {updated['license_plate']} now {updated['ownership']}")

Update Fuel Type and Recalculate Emissions

Switch a vehicle to electric fuel to see emissions change:

def switch_to_electric(vehicle_id, electric_fuel_id):
    """Switch vehicle to electric fuel"""
    payload = {"vehicle_fuel_id": electric_fuel_id}

    response = requests.patch(
        f"https://api.dcycle.io/v1/vehicles/{vehicle_id}",
        headers=headers,
        json=payload
    )

    vehicle = response.json()
    return {
        "vehicle_id": vehicle["id"],
        "new_fuel": "electric",
        "co2e": vehicle["co2e"]
    }

# Get electric fuel ID first, then switch
electric_vehicle = switch_to_electric(
    "550e8400-e29b-41d4-a716-446655440000",
    "880e8400-e29b-41d4-a716-446655440000"
)
print(f"New CO2e after electric switch: {electric_vehicle['co2e']} kg")

Update Multiple Vehicles Simultaneously

Update vehicles in bulk:

def bulk_update_vehicles(updates):
    """Update multiple vehicles with new information"""
    results = []

    for vehicle_id, update_payload in updates.items():

        "name": "Rental Van"
    }
}

updated_vehicles = bulk_update_vehicles(updates)
print(f"Updated {len(updated_vehicles)} vehicles")

Rename Vehicle Fleet

Update vehicle names for better organization:

def rename_vehicle(vehicle_id, new_name):
    """Rename a vehicle"""
    response = requests.patch(
        f"https://api.dcycle.io/v1/vehicles/{vehicle_id}",

        json={"name": new_name}
    )

    return response.json()

# Rename vehicles
