We're using Drupal and wanting to use Drupal forms that submits a Marketo form via API.
I dearly hope you mean the Forms API and not another API.
Don't see what this really has to do with Drupal. The Marketo Forms API can forward UTMs (assuming you are also capturing those UTMs into Marketo form fields). See my answer here from earlier today: Using a token for a form follow up page
Thanks for your help, Sanford!
