API Jitsy - Room conference

Hi,

I would like to allow users of my website to create rooms with the API of Jitsy. sorry if the question is basic but I am a beginner and I don’t success to do it. When I use the code found on a forum below, there is no possibility to create a room:

For your information, I don’t have any server and I don’t know if I should get one.
I would appreciate your help !
Thanks,

Best,

Anthony
