Hi,

A simple way to do it, is to use the built-in library lodash.

e.g.
const randomNumber = _.random(1000000000,9999999999)

If you need to use it in a request, you can add this to a pre-request script like this:

const randomNumber = _.random(1000000000,9999999999)
pm.variables.set(‘randomNumber’, randomNumber )

then in the request body, add {{randomNumber}}

e.g.

{
    "username": "Test",
    " number": "{{randomNumber}}"
}

I hope this helps.

Update:

With lodash being deprecated from the built-in libraries, you must load it first.

const {random} = require(‘lodash’)

const randomNumber = random(1000000000,9999999999)
pm.variables.set(‘randomNumber’, randomNumber )

or use native javascript like this:

function generateRandomNumber() {
const min = 1000000000; // Minimum value
const max = 9999999999; // Maximum value
const randomNumber = Math.floor(Math.random() * (max - min + 1)) + min;
return randomNumber;
}
const randomNumber = generateRandomNumber();
console.log(randomNumber);
