I want to get information from a web socket running on a website. however since I am not aware of handshaking process I am unable to establish a successful connection to the websocket and retrieve the information being published on the websocket. I assume this falls on the website confidentiality and unless they provide me the documents it is highly unlikely I can get the data directly from the websocket (please correct me if I am wrong).

However since I can view the data from "WS" tab in network section of the chrome (developer mode). I was wondering if there is a way to replicate this programmatically using selenium or any headless browser and I get this information inside my program. my main objective is to get the information using C# however I am open to any other way to get this data.

Note that you should wait until the chrome driver quit. Then in console you'll see the sent and received messages
