Is it possible to listen to all HTTP request / response of k6 Browser?

Hello community,

I need to execute log in on my webpage using k6 browser and get access_token and refresh_token as response from “…/oauth2/v2.0/token” endpoint.

Is it possible to listen to all HTTP request / response while k6 Browser works (like in Network tab of Chrome Dev mode) and output data to console without interrupting the browser flow?

In the next step, I will use access_token and refresh_token in k6 normal testing script (not the browser).

The problem is, I can’t recreate authentication process using normal testing script in k6, that’s why I had idea to use k6 browser to get access_token and refresh_token.

import { browser } from 'k6/experimental/browser';
import { sleep } from 'k6';

export const options = {
  scenarios: {
    browser: {
      executor: 'shared-iterations',
      options: {
        browser: {
          type: 'chromium',

let tokens = {};

export default async function () {
  const page = browser.newPage();

  try {
    console.log('Navigating to main page');
    await page.goto('');
    console.log('Navigation main page successful');

    await sleep(0.5);

    await, 650);
    console.log('Performed click at coordinates');

    await page.waitForNavigation({ waitUntil: 'load' });
    console.log('Navigation to the next page completed');

    await sleep(0.5);

    await page.locator('input[name="email"]').type('www');
    await sleep(0.5);

    await page.locator('input[name="password"]').type('eee');
    await sleep(0.5);

    await, 340);
    console.log('Performed click at coordinates');

    //I want to get list of all response headers in console
    //Need to get access_token and refresh_token from response "token"

    await page.waitForNavigation({ waitUntil: 'load' });
    console.log('Navigation main page successful and page fully loaded');

    // Check if tokens are available
    if (tokens.access_token && tokens.refresh_token) {
      console.log('Tokens successfully retrieved');
    } else {
      console.error('Failed to retrieve tokens');

    await sleep(20);
  } catch (error) {
    console.error('Error during navigation:', error.message, error.stack);
  } finally {
    // Always close the page after operations are done
    await page.close();
    console.log('Browser closed');

Hi @emerziian,

Currently, there’s no way to listen for the k6 browser’s HTTP request/response events.
