Add a hidden field to a KickoffLabs form

Last reviewed: 2026-09-23

A hidden field carries a value with a signup while staying out of the visitor’s form. Use it for a fixed source label or another value your team needs in lead records. Do not use it for a secret; browser form data can still be inspected by visitors.

In Pages & forms, edit the KickoffLabs page and open Settings → Page → Signup form → + Add field → Hidden Field. Give the field a label and Default value, then add it to the form. Publish the page and submit a fresh test lead. Open that lead’s Lead details to confirm the captured value before depending on it in a segment or integration.

The tested KickoffLabs picker exposes a fixed default value. It did not show a URL-parameter mapping control, so do not assume this field will automatically capture a changing UTM value. For campaign-level source analysis, use the lead’s acquisition data and Reports.
