Integrate utm parameters as a tag from Instapage to Infusionsoft

I can integrate Instapage forms with Infusionsoft, but I don’t know how to do utm parameters. In instapage, I create it as a hidden field in the form (for example ?utm_source=facebook). When integrating with Infusionsoft fields, what do I do so that a tag is attached when the form goes to Infusionsoft (for example Facebook)?
