Client-Server: Set sync parameters in endpoint

[wismna]

In a client-server architecture, I'm setting some sync parameters in the client and sending them over to the server, which works.
I would like to set some parameters in the endpoint, when it handles the request: WebServerAgent.HandleRequestAsync(HttpContext);, the reason being that I would like the server to have the responsibility of setting some of them (e.g. based on information contained in a bearer token) instead of letting the client set them.
I couldn't find anything in the docs or in the code regarding this, is there a way to do this ?
