Set up SourceTag with HubSpot

When a visitor submits a form with SourceTag data, the attribution properties need somewhere to go in HubSpot. You need to create custom contact properties that match the SourceTag field names.

What you need

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

Step 1: Go to contact properties

In HubSpot, navigate to Settings > Properties.

Step 2: Create custom properties

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

Core properties (create these)

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

Optional extended properties

Property name	Label	Type
st_fc_click_id	First Click Click ID	Single-line text
st_lc_click_id	Last Click Click ID	Single-line text
st_visits	Visit Count	Number
st_days_to_convert	Days to Convert	Number
st_device	Device Type	Single-line text

See Captured Fields for the full list of available fields.

Step 3: Map form fields to CRM properties

If your form builder sends data to HubSpot via an integration (Zapier, native feed, webhook, etc.), make sure the SourceTag form fields are mapped to the corresponding HubSpot custom properties.

Step 4: Test

Submit a form with UTM parameters and check the contact record in HubSpot. The custom properties should be populated with attribution data.

Tips

• Create a “SourceTag Attribution” property group to keep things organised.
• The property internal name in HubSpot must match the form field name. HubSpot may modify internal names automatically.
• Test with a fresh contact (not one that already exists) for the cleanest test.
