# How to create a macro script
Directory for macro scripts /application/macros/.
To add new macro, we'll create a file /application/macros/randomx.php with code:
<?php
namespace Macros;
use Traffic\Model\BaseStream;
use Traffic\RawClick;
use Traffic\Macros\AbstractClickMacro;
class randomx extends AbstractClickMacro
{
public function process(?BaseStream $stream, RawClick $click, $min, $max)
{
return rand($min, $max);
}
}
Make sure that class name and file name are the same.
In order to send parameters to macro script, just specify in macro:
{random:100,999}
It will send $min = 100 and $max = 999
To read more about $stream and $rawClick read page Internals.
