Automation fill marketo form from URL parameters

[Orij]

Hello comunity is there any way to auto fill my marketo form from URL parameters like first name, last name, email etc?

Yes, technically you can use the JS for this, but in general using PII in the URL parameter doesn't sound very solid to me (I stay a bit wary of it). What is your exact use case here?

Here's the script written by Sandy for accomplishing this in case you'd like to refer.

You are the best 🙂 thank you very much my friend 🙏 
Each client will receive his own link and a form will already be filled out for him, thats the idea...

Are you not using a form on a Marketo LP, then?

@SanfordWhiteman I am using the marketo form on my landing page if i understood your question correctly

So why not use the built-in Pre-Fill feature? Or are you constructing these links outside of Marketo emails?

I think for sure it's a better choise but im new here so i don't know all nuances 🙂 
Thank you @SanfordWhiteman

Marketo tracked links can Pre-Fill fields on Marketo forms, as long as they're named forms (mktoForm elements) on Marketo LPs. (There's another method that works on non-Marketo pages, if you search past posts.)

So all you need to do is make sure the fields are enabled for Pre-Fill.

@Orij, here is Sandy's blog on how to implement the Marketo form prefills on external web pages. You're better off implementing this and relying on the native form prefill for users landing on Marketo LPs from a tracked email link than storing PII in the QPs.
