I'm learning how to use the HttpService. A very useful way to apply HttpService is through user created web APIs, such as roproxy.pw. However, I'm having a hard time utilizing these APIs because I can't figure out the syntax behind them. For example, an API of roproxy.pw is GetIdByUsername (which is rather self-explanatory.) The site lists the API's name and its arguments, but I don't know how to call it.
How do I use user created web APIs?
