Enrich HubSpot Contacts with ExactBuyer using n8n

What This Automation Does

This workflow watches for new contacts created in HubSpot.

It then gathers basic info like email and contact ID.

Next, it calls the ExactBuyer API to add details like job title, phone, and social profiles.

After that, it updates the HubSpot contact with this new data.

This saves many hours of manual work and makes contact info better for marketing and sales.

How This Workflow Works: Input → Process → Output

Input

• New contact creation event in HubSpot triggers the workflow.

Processing Steps

• HubSpot Trigger node detects the new contact.
• HubSpot Get Contact node fetches full contact details using the contact ID.
• Set node extracts user ID (VID) and email from the response.
• If node checks if email exists; only continuing if it is present.
• HTTP Request node calls ExactBuyer API with the email to get extra info.
• HubSpot Update Contact node writes enriched data back to HubSpot.
• NoOp node handles errors if ExactBuyer does not respond, so workflow continues smoothly.

Output

• HubSpot contact updated with job title, phone, company size, social links, and other enrichments.
• Error handling maintains workflow stability, avoiding crashes.

Who Should Use This Workflow

This workflow fits people who use HubSpot for marketing and sales.

If there are many new contacts each week but trouble keeping data complete and useful, this helps save time.

It is good for teams wanting up-to-date contact info automatically added without manual work.

Customizations
