Where to find these settings

Open the Form Settings dialog (press ⌘, in the editor, or click Form settings in the editor’s top tab bar) and select Tracking.

​
UTM parameter capture

UTM parameters are tags added to URLs that identify which campaign, source, or ad brought a visitor to your form. When enabled, Filla reads these parameters from the form URL and saves them to fields in your Airtable table.

​
Enabling UTM tracking

Toggle Capture UTM parameters to on. Six field mapping options appear:

​
Mapping fields

Each parameter has a field picker. Select an existing single-line text field from your Airtable table, or click the create button to add a new field directly from the picker. When a respondent opens your form from a URL like:
Filla captures those values and writes them to the mapped fields when the form is submitted. UTM capture happens server-side on submit, so it works even if you don’t put a hidden field on the form itself.

​
IP address capture

Record the respondent’s IP address for fraud prevention, geographic analysis, or compliance.
Capturing IP addresses may have legal implications under GDPR, CCPA, and other privacy regulations. Make sure your form’s privacy policy discloses IP collection and that you have a lawful basis for processing this data.

​
Use cases

  • Campaign attribution: Track which marketing channels drive the most form submissions by mapping UTM parameters to Airtable fields, then building reports in Airtable views.
  • Fraud prevention: Use IP addresses to identify suspicious submission patterns or duplicate entries from the same network.
  • Geographic analysis: Combine IP data with a geocoding tool to understand where your respondents are located.
