# Dynamic Variables (Parametrization) Just like the [Postman](https://learning.postman.com/docs/writing-scripts/script-references/variables-list/), Ddosify supports dynamic variables. Actually, we support all the random methods Postman supports. If you use `{{$randomVariable}}` on Postman you can use it as `{{_randomVariable}}` on Ddosify. Just change `$` to `_` and you will be fine. For example, to generate fake integers, you can use `{{_randomInt}}` on *URL, header, body or basic authentication.* To simulate a realistic load test on your system, Ddosify sends every request with the new random value that corresponds to the variable you provide. If you wonder, Ddosify uses [go-faker](https://github.com/ddosify/go-faker) library to generate fake data. Here is the list of all available dynamic variables. ### Common
