HTML hidden inputs in forms

Reduce friction by filling-in hidden fields with custom data from the URL. Automatically get user information from cookies and tracking parameters, like UTMs. Enrich your user database and improve your marketing strategy without effort.

How it works

Create a hidden field. Click on the ‘Hidden fields’ button, on the upper part of the form editor, to add a hidden field to the form.

Give it a name. Add the field name in the left column. If you're getting a parameter out of the URL, just make sure their names match.

Reference its value. Add a fixed value on the right column, if needed. If you haven't set any values from the URL nor the SDK, they will be automatically taken.

Publish and test it. Publish the form and click on the ‘Preview’ button to test it.

Check the data. Go to the ‘Submissions’ tab to see the list of field values, including the hidden fields. Then click on ‘Metadata’ to see additional values and details about the submission, including the URL and UTMs you have set.
