Hi Nicole M,
Is it possible to do the same when the form is embedded on a non-marketo landing page? I assume there's some code that can be added to the form embed code to determine the thank you page URL but wasn't able to find it in the community.
Lucho, check last night's blog post http://blog.teknkl.com/same-page-thank-you-text-with-marketo-forms-about-the-aliid/
You can see that the Thank You URL (or Thank You behavior in general) is easily overridden using the onSuccess listener.
