System variables

NativeRest uses built-in library to generate sample data, including random names, addresses, email addresses, and much more. You can use these pre-defined variables multiple times to return different values per request.

You can use these variables like any other variable in NativeRest. Their values are generated at the time of execution and their names start with {{, for example {{random.uuid}} or {{timestamp}}.

You can also use shortcut Ctrl + Y to open System Variables window.
