Rstudio server authentication problem

Hello,

I'm trying to send request to a rstudio-server from a website.
Every time i send a request to an endpoint i get asked for authentication if i'm trying to get to the endpoint in a different way (different browser, curl ecc...).
The website will send various requests to the rstudio-server, and i don't know if there's a way to automatically authenticate of if there's a way to skip the authentication process.

Thanks you
