how to convert this yaml service call?

[phsdv]

It is more a yaml question than pyscript :-) How would you convert this yaml service call to pyscript?

  - service: tesla_custom.api
    data:
      command: CHARGING_AMPS
      parameters:
        path_vars:
          vehicle_id: '{{ state_attr(''binary_sensor.carname_online_sensor'', ''id'') }}'
        charging_amps: '16'

The syntax is: service.call(domain, name, **kwargs)
But I don´t understand yaml good enough. The domain is, I think, tesla_custom.api, but then I am lost

If I did not mess up the syntax:

carname_online_sensor_value = state.getattr('carname_online_sensor')['id']

service.call('tesla_custom', 'api', 
            command=CHARGING_AMPS, 
            parameters=dict(
                path_vars=dict(
                    vehicle_id=carname_online_sensor_value
                ),
                charging_amps='16'
            )
        )

# or
tesla_custom.api(
    command=CHARGING_AMPS, 
    parameters=dict(
        path_vars=dict(
            vehicle_id=carname_online_sensor_value
        ),
        charging_amps='16'
    )
)

Great, thanks.
CHARGING_AMPS needs "", as I got an undefined error. After changing that it works!
This is what I ended up with:

vid = binary_sensor.carname_online.id
tesla_custom.api(
    command="CHARGING_AMPS", 
    parameters=dict(
        path_vars=dict(vehicle_id=vid),
        charging_amps='16'
        )
    )
