Webhook "make web request" URL?

Hi Im doing home automation project. I want to make a webhook and when I make web request, I need URL where to send it and dont know what url is that?

I`m using IFTTT. So, IF google assistant receve voice massage, THEN webhook "make web request"..
It could be done?

may be you mean you want to use the Arduino IoT Cloud API?

https://www.arduino.cc/reference/en/iot/api/

Thanks, but I'm new to this..what part of api shuld I look at?
Btw is this the right way to do it (as I described) or is there a more simple way?

It’s not an arduino question - it’s specific to your setup

The doc explains How to send a POST message with the right identification. I have no clue how you build or code such a request with your Google thingy

Sorry you're right, is there any example, how to do something simple like changing the state of the arduino cloud iot led widget (variable) , with the google assistant voice message?
