Puppeteer get 3rd-party cookies

Question

How can I get 3rd-party cookies from a website using Puppeteer?

For first party, I know I can use:

await page.cookies()

Answer 1

You can create a Chrome DevTools Protocol session on the page target using target.createCDPSession(). Then you can send Network.getAllCookies to obtain a list of all browser cookies.

The page.cookies() function will only return cookies for the current URL. So we can filter out the current page cookies from all of the browser cookies to obtain a list of third-party cookies only.

const client = await page.target().createCDPSession();
const all_browser_cookies = (await client.send('Network.getAllCookies')).cookies;
const current_url_cookies = await page.cookies();
const third_party_cookies = all_browser_cookies.filter(cookie => cookie.domain !== current_url_cookies[0].domain);

console.log(all_browser_cookies); // All Browser Cookies
console.log(current_url_cookies); // Current URL Cookies
console.log(third_party_cookies); // Third-Party Cookies
