Marketo Form Pre-fill when arriving from external source, but with authentication
We created a Marketo Preference Center that is hosted on a Marketo Landing Page and has Pre-fill enabled. When customers arrive at this page via a Marketo email, everything works perfectly and their existing preferences are pre-filled.
However, we'd like to give our clients the option of accessing this page also from their externally hosted client account, where they've already signed in. Is there a way to bring them to this Marketo LP, authenticate them in some way on the backend, and pre-fill their preferences?
