Action: Rest API Call

Hi

I have a climate.panasonic_aircon enity. I can control the air conditioner through service: climate.set_operation_mode. Sometimes the operation mode of the air conditioner changes outside of hass. I have the ability to check this change through a sensor that monitors the angle of the air conditioner vent. I want to create an automation that changes the state of climate.panasonic_aircon. I am able to do this in the web interace by using the states part of home assistant.

Enitity
climate.panasonic_aircon

State
any string of text

State attributes (JSON, optional)
{
  "current_temperature": 21.2,
  "min_temp": 16,
  "max_temp": 30,
  "temperature": 23,
  "target_temp_step": 1,
  "fan_mode": "auto",
  "fan_list": [
    "low",
    "mid",
    "high",
    "auto"
  ],
  "operation_mode": "idle",
  "operation_list": [
    "idle",
    "cool",
    "heat"
  ],
  "unit_of_measurement": "°C",
  "friendly_name": "Panasonic Aircon",
  "supported_features": 193
}

[ SET STATE BUTTON ]

How do i insert the above into an automation eg.

- alias: 'change aircon state to off'
  trigger:
  action:
    # service call to api to change state

Thanks
