How to add hidden fields?

Hidden fields allow you to pass data to your form submission without the user seeing the field. This is perfect for tracking sources, campaign IDs, or user IDs.

How to add hidden fields

1. Go to your form settings.
2. Navigate to the Share tab.
3. Scroll down to the Hidden fields section.
4. Click Add new row and select the field you want to hide from the dropdown.
5. The Embed Code will automatically update to include these parameters.
6. If you're using the Share the link tab instead, the share URL will automatically include ?hidden=... query parameters.

[!NOTE] This feature is available with both the Embed to the web page and Share the link options. When sharing a link, hidden field IDs are appended as URL query parameters.

Use Cases

• Tracking Sources: Add source=facebook or source=newsletter to your links to know where your submissions are coming from.
• User IDs: Pass a user ID from your application to link the submission to a specific user in your system.
