Pass data into the hidden field by appending parameters to the form's URL, such as UTM tracking values or referral sources.

Open the form using a test URL with sample parameter values to confirm the hidden field captures the data correctly.
04Use hidden data in automations
Connect the hidden field data to CRM tools, marketing platforms, or automation workflows for tracking and analytics.
