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.
