Form Prefill Functionality is not working in embed form

Anonymous · ‎09-25-2017

Hi

I have used the embed code of the form in the marketo LP and to prefill the form I am using rest API's of the marketo but I am getting the error " No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin is therefore not allowed access.".

Please let me know if anyone has solved this type of problem.

Never, ever, ever even think about exposing the REST API directly from a webpage. The security and reliability consequences are absurd. Honestly, you should shut down your web presence before considering this.

In your case, there's no need to consider this. If it's a Marketo LP using the embed code instead of a named Form element (not advisable, but you can do it if you insist) then you can for the most part fill the form using tokens:

MktoForms2.whenReady(function(form){
  form.setValues({
    LastName : "{{Lead.Last Name}}"
  });
});

Also be aware that multiple Marketo forms with the same ID on the same page have subtle problems (yes, even if one of them is set to display: none;). You can check some of my posts here for pointers.
