SourceTag

Form Setup

Set up SourceTag with Gravity Forms

SourceTag populates hidden fields in your forms with attribution data. For Gravity Forms, you need to add those hidden fields to your form first.

What you need

  • SourceTag installed on your site (script tag or WordPress plugin)
  • A Gravity Forms form

Step 1: Open your form in the Gravity Forms editor

Go to Forms > Edit on the form you want to track.

Step 2: Add hidden fields

From the “Advanced Fields” section, drag a Hidden field onto your form. Repeat for each field you want to capture.

Core fields (add these)

Add a hidden field for each of the following. Set the Field Label to the field name:

  • st_fc_channel
  • st_fc_detail_1
  • st_fc_detail_2
  • st_fc_detail_3
  • st_fc_detail_4
  • st_lc_channel
  • st_lc_detail_1
  • st_lc_detail_2
  • st_lc_detail_3
  • st_lc_detail_4
  • st_fc_landing_page
  • st_lc_landing_page

Optional extended fields

If you’ve enabled extended field groups in your SourceTag dashboard, also add hidden fields for those. Common ones:

  • st_fc_click_id and st_lc_click_id (click IDs)
  • st_visits (visit count)
  • st_days_to_convert (days since first visit)
  • st_device (device type)

Step 3: Set the field name

For each hidden field, click on it and go to the Advanced tab. Set the Parameter Name (under “Allow field to be populated dynamically”) to the field name (e.g. st_fc_channel).

Tick Allow field to be populated dynamically and set the parameter name to match the field label exactly.

Step 4: Save and test

Save your form. Visit a page with this form using UTM parameters:

?utm_source=test&utm_medium=cpc&utm_campaign=test-campaign

Submit the form. Check the Gravity Forms entry. You should see the attribution data in the hidden fields.

Tips

  • You can copy field names from the Fields page in your SourceTag dashboard (each name has a copy button).
  • The hidden fields won’t be visible to visitors. They only appear in form entries and notifications.
  • If you’re sending Gravity Forms data to a CRM, make sure to map these fields in your CRM feed.
