Set up SourceTag with Attio

When a visitor submits a form with SourceTag data, the attribution fields need somewhere to go in Attio. You need to create custom attributes on People records that match the SourceTag field names.

What you need

• SourceTag installed and form hidden fields set up
• Attio account with admin access

Step 1: Go to custom fields settings

In Attio, navigate to the People object and open the attribute settings.

Step 2: Create custom attributes

Create a new custom text attribute for each SourceTag data point:

Core fields (create these)

Field name	Label	Type
st_fc_channel	First Click Channel	Text
st_fc_detail_1	First Click Smart Field 1	Text
st_fc_detail_2	First Click Smart Field 2	Text
st_fc_detail_3	First Click Smart Field 3	Text
st_fc_detail_4	First Click Smart Field 4	Text
st_lc_channel	Last Click Channel	Text
st_lc_detail_1	Last Click Smart Field 1	Text
st_lc_detail_2	Last Click Smart Field 2	Text
st_lc_detail_3	Last Click Smart Field 3	Text
st_lc_detail_4	Last Click Smart Field 4	Text
st_fc_landing_page	First Click Landing Page	Text
st_lc_landing_page	Last Click Landing Page	Text

Optional extended fields

Field name	Label	Type
st_fc_click_id	First Click Click ID	Text
st_lc_click_id	Last Click Click ID	Text
st_visits	Visit Count	Number
st_days_to_convert	Days to Convert	Number
st_device	Device Type	Text

See Captured Fields for the full list of available fields.

Step 3: Map form fields to CRM fields

If your form builder sends data to Attio via an integration (Zapier, Make, webhook, etc.), make sure the SourceTag form fields are mapped to the corresponding Attio custom attributes.

Step 4: Test

Submit a form with UTM parameters and check the person record in Attio. The custom attributes should be populated with attribution data.

Tips

• Attio uses the term “attributes” rather than “fields”. Create these on the People object.
• The attribute slug in Attio must match the form field name in your integration mapping.
• Test with a fresh contact (not one that already exists) for the cleanest test.
