Hidden Field

A hidden field stores a value that is included in the submission but is not shown to the end user. It is useful for passing metadata along with a submission — for example, a campaign ID, a source identifier, or a pre-filled value from the page URL.

Settings

Name — The field identifier used in the submission data.

Value — The value that will be submitted. This can be a fixed string.

Required — Marks the field as required. If the value is empty at submission time, the form will block submission with a configurable error message. This is mainly useful when the value is expected to be injected dynamically.

Custom required message — The error message shown if a required hidden field has no value.

Common use case

Set a fixed value such as a campaign name or a page slug, and include it in the webhook or email action payload to identify where the submission came from.
