s&box provides a static Http class, this lets you easily create asynchronous HTTP requests of different methods (GET, POST, DELETE, etc…) providing JSON content and parsing JSON responses.
Allowed URLs
You can only use http orhttps URLs to domains (no IP addresses), and to prevent abuse, localhost is permitted only on ports 80/443/8080/8443.
:::info
The command line switch -allowlocalhttp will let you access any local URL from the server.

Cheat Sheet
Some common things you might want to do…
// GET request that returns the response as a string
string response = await Http.RequestStringAsync( "https://google.com" );
// POST request of JSON content ignoring any response
await Http.RequestAsync( "https://api.facepunch.com/my/method", "POST", Http.CreateJsonContent( playerData ) );
