Turning off cookie'ing

[Anonymous]

All,

Laws in countries outside of the US have cookie compliance that say websites have to disclose if they are collecting cookie data and allow visitors to opt out.  I know we Marketo users can turn off form prefill at the form level, but is it possible to do it at the lead level?

Example: Person opts out of cookie'ing on the website and that triggers a flow step to disable form prefill just for that lead.

You can't use a Flow step because that means you are tracking the lead! Cookies are about more than PreFill.

To disable cookies, first make sure you're running the latest Munchkin (http://munchkin.marketo.net/munchkin-beta.js).

Then give users a link to a page with the query param

  marketo_opt_out=true

in the URL.

Correction: though this feature is now officially documented -- previously, it was unofficially claimed but not implemented in reality -- it doesn't work without an additional hack, which I'll publish on my blog.
