Http binding for receiving events?

Can I configure an http binding thing to ACCEPT http/GET requests from an IoT device??
I read the documentation about http binding and probably know already the answer. Just wanna be sure…

I know that there exists other ways of achieving this (servlet call (basicui/CMD?itemName), PHP-Server, node-red, …)

No.

Presumably you want to push or pull data into openHAB initiated by your IoT device? If so, use the openHAB REST API.

correct. the IoT device should push data into openHAB (because it is an event). But as said, I cannot use openHAB REST API as the IoT device does not support http/POST requests
