Use IFTTT trigger for sonoff switch

Hi, I wish to create a automation in HA that when Xiaom door sensor is open switch on light of Sonoff Touch via IFTTT.
Can someone help me?
First I need to create a trigger in IFTTT that switch on my Sonoff Touch… without conditions… but I’m a newbe and I’m not able to do it.

make an applet for THIS use webhooks to recive a Receive a web request use whatever name you want (triger_name_here) for THAT use eWeLink Smart Home and choose witch sonoff to turn on

then on homeassistant use this

ifttt:
  key: !secret ifttt_key  

automation old:
  - alias: turn on sonoff
    trigger: 
      platform: state
      entity_id: your.sensor_name_here
      from: 'off'
      to: 'on'
    action:
      service: ifttt.trigger
      data: {"event":"triger_name_here"}

if you dont have IFTTT component set up use this https://home-assistant.io/components/ifttt/ guide to set it up

Thank you Ken.
Now I have to create a trigger in IFTTT…
I login in IFTTT,

  1. choose New Applet
  2. choose the service eWeLink
  3. choose the trigger “1 channel switch turn on or off”
  4. set the name_sensor and turned “on”
  5. and then… what action I should choose???

Guys wonder if I can ask as it is possible with native IFTTT and ewelink to turn light on and off is it possible in teh same way to make them flash say 20 times

Sorry if it is a stupid question

no it is not possible to flash the lights with IFTTT and eWelink app
but you can flash your sonoof with tasmota firmware there are tutorials on youtube its really easy to do it
