Use "Marketo unique code" for forms and lead tracking in external LPs

[WolframLotz]

Hi, 
I activated pURLs in our account and fixed them on our Marketo Landingpages like Sanford suggested in https://blog.teknkl.com/tag/purl/. This works pretty fine. 

As most of our website activities are done on our regular (non-Marketo) website I was wondering if I can use "Marketo unique codes" there in any way? 

E. g. is it possible to enter the unique code in a form (e. g. as hidden field) to associate the form fill with a specific user? 
Is it possible to prefill my forms on a non-Marketo LP by using the Marketo unique code or a similar identifier? 

Is it possible to use the unique code in the API? 
(There is no API name shown but you can as well us a lead id in the API and the lead id is not even menitioned in the Field Manager)

Do you know any more use cases you can use the unique code for beside sharing personalized URL for Marketo Landing Pages?

Thanks and Kind regards
Wolfram

The Marketo Unique Code/Marketo Unique Name has some cool uses outside of (visible) Marketo pURL-enabled LPs — but they all require custom dev.

You can’t simply include the MUC in a hidden field to associate the Munchkin session/form post. But you can use a hidden pURL-enabled LP (in an IFRAME) to accomplish the same.

@WolframLotz ,

you can do a lot of NON pURL based form fills.  @SanfordWhiteman has posted a few times on this, and has an amazing blog post over here https://blog.teknkl.com/pre-fill-any-site-any-form/

Cheers
