Get referring URL for Flask request

When a user visits our site and signs up, how can I capture which website they came from?

Be it search, a PR website, etc. I don't care what page from our site they visited, I just want to know which marketing efforts are giving us the most signups.

I know Google Analytics can probably do this but I'd like to have something internal for reference as well.

Solution

  • request.referrer contains the URL the request came from, although it might not be sent by the client for various reasons.

    The attribute takes its value from the Referer (not a typo!) header:

    referrer = request.headers.get("Referer")

    or, using the Flask shortcut:

    referrer = request.referrer

    See this tutorial for an example.
