  +## Calling your function
  +
  +Since all functions deployed through Web Template Studio are HTTP Triggers, you can invoke a function with an HTTP request.
  +You can use your favorite HTTP Client library (for example Axios, Fetch, Request etc.) to hit the endpoints exposed
  +by your function application. An individual function (assume it's called `function1`) under an application with _appName_
  +`my-functions-app` is available at `my-functions-app.azurewebsites.net/api/function1`.

  +### Examples
  +
  +Let's assume we have a Hello World function application with appName `my-functions-app` and a function `function1` that returns _"Hello,
