Get your cookies using PhantomBuster's browser extension
To make your life a little bit easier, we've got a browser extension that will automatically retrieve your cookies for you. The extension will work for all Phantoms and social networks on our store, so you only have to install it once.
Once you've done this, refresh the page of your Phantom's setup and you'll see a new "Connect to..." button:
Simply click it, and your cookie will populate the box automatically! It'll look something like this:
Get your cookies manually
Open a new tab and go to the website which you want your cookies for. Right-click anywhere on the page and open "Inspect":
Locate the "Application" tab. Then select "Cookies" > "http://www.websiteyoureafter.com". Locate the cookie you're looking for (so, for example, for LinkedIn you'll be looking for the "li_at" value):
Copy this and paste it back into the relevant field in your Phantom's setup.
The table below contains each social network's cookie name should you need to find them:
You're all set!
Make sure not to manually log out of the site you've retrieved your cookie for, as this will cause it to expire, as well as not taking the necessary automation rate limits into account.
If you find that yours are not working and are expiring too often, check out this article.
