How to Add Hidden Fields in Typeform

Quick summary

Hidden fields in Typeform let you capture extra data — like source, campaign, or user ID — through URL parameters without showing those fields to respondents. This guide walks you through the Workflow panel to create, name, and share a form link with hidden field parameters already embedded.

Steps

1. Open your form from your workspace to get started with the editor.
2. At the top of your screen, click "Workflow" to access form automation options.
3. Click on the "Pull data in" option to set up your URL parameters.
4. Click "+ Add new parameter" to create a new hidden field.
5. Name your parameter using lowercase letters and underscores instead of spaces.
6. Click "Save" to confirm your new parameter.
7. Head over to the "Share" panel after publishing your form to see your parameters in action.
8. Click "Copy link" to grab your form URL with the parameters included, ready to paste wherever you need it.
