4 node switch returns only 1st switch status in toggle webhook

I m trying to use tinxy api. I am able to do the following

  1. GET List of devices https://backend.tinxy.in/v2/devices
  2. POST get the state https://backend.tinxy.in/v2/devices/{deviceId}/state

Here when I get the state it’s always for the first switch in a 2 or 4 switch module but how to get the second third or fourth switch state?

Pls help
