Documentation for HTTP requests: PUT vs POST vs GET?

I searched here & elsewhere. This thread (almost 3 years old) may have helped some.

Could someone give me or point me to more of such documentation preferably with some examples & perhaps how the requests are like other OpenHAB code (like postUpdate, maybe)? Thanks.

What exactly are you trying to do? If you look at the REST API (UI) it has some basic info in what each Http method does.

Thanks again, Lucky. After my recent confusion in using HTTP POST instead of GET, I was trying to be more informed.

Thanks also for REST API hint. Searching for “REST API (UI) HTTP methods,” I was able to find some documentation to study & get some understanding.
