Chrome Flags Reference

--force-variation-ids

What does --force-variation-ids do?

Forces additional Chrome Variation Ids that will be sent in X-Client-Data header, specified as a 64-bit encoded list of numeric experiment ids. Ids prefixed with the character "t" will be treated as Trigger Variation Ids. IMPORTANT: You can use this switch for test purposes (e.g. a manual command line run or from a unit test), but NOT for production code in the browser, as the latter is not allowed for privacy reasons (except for the current use by about:flags code).

Usage

chrome --force-variation-ids

const browser = await puppeteer.launch({
  args: ['--force-variation-ids']
});

const browser = await chromium.launch({
  args: ['--force-variation-ids']
});

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--force-variation-ids')
