How do I send custom cookies for a login-protected supplier?

Some wholesale and B2B suppliers hide pricing behind a login.

The easiest way in is the Chrome extension: it imports from your logged-in browser session directly, so there is no cookie string to copy. Custom cookies are the manual alternative if you would rather paste a URL.

To let the URL scraper see logged-in pricing instead:

Open the Data Sourcing tab and turn on Send custom cookies.
Paste a cookie string from your logged-in browser session into Cookie value, in the format session_id=abc123; token=xyz789.
The scraper attaches that cookie header so it can see authenticated pricing and content.

Treat your cookie string like a password. It grants access to your logged-in session, so only use it for suppliers you trust, and refresh it if it stops working. If cookies alone are not enough, contact support with the supplier URL.
