Send a requests to a magnet links shortener which doesn't have APIs

[snippsat]

But I found many more request headers than the ones you put insede the python dictionary (see image below), so may I ask you how to choose what are the ones needed to be put in the dictionary?

Can put all dictionary,but if test can get away with less.
So my guess was that XMLHttpRequest was needed,some need cookie(can make trouble as more step may be needed) but not here.
