Need some help with understanding the janus api

Hello, I’m an IT student from the Netherlands, and I want to use Janus. Currently, I have it running on Docker, and the examples work fine. However, I am having some trouble understanding the API. How do I create video rooms and destroy them? I have read the documentation, but I didn’t understand the proper application. Currently, I am using Postman to access the API.

Please review here, and read the following : Janus - General purpose WebRTC server⁤ (meetecho.com) , the best way to have a good understanding of this test it out on your own environment or even try to recreate the examples, it will give you a proper incite, but I highly urge you to first understand WebRTC⁤ itself for it to make sense as well.
