Simple button platform

Hi there. I am coming from homebridge where this was a quick endeavour. I am totally new to HA but I am learning eagerly!

I have a flic button which sends out a http request. I want HomeAssistant to do an action when it receives such a request. I am a little overwhelmed with the options, what would be an easy way?

This?
