Door opener command http

sorry for the stupid question, but I’m very new in OpenHAB and I have the same issue to integrate a door opener relay over http. Only one http command I can send to the door station
and I wand to integrate in my openhab a switch to open the door.
My problem is that I don’t know how to integrate it in openhab.
Which binding I need? http-binding was used by the solution from Peter? (refering to topic 29877)
Must I create an thing and whitch one?
Which item must I create and where to integrate the command?

Sorry for the stupid questions, bur I saw this blog and this could solve my problem. Sorry, I’m totally beginner…

Thanks a lot!
