This template enables fully automated lead enrichment using Surfe’s bulk API. Simply drop a Google Spreadsheet into your Google Drive, and n8n will handle everything — from reading the leads, enriching them in batches, filtering valid data, and pushing results to HubSpot.

1. ❓ What Problem Does This Solve?

Manually enriching contact lists is tedious, error-prone, and doesn’t scale. Whether you’re importing leads from events, marketing forms, or partners, this workflow ensures each record is enriched and synced to your CRM — hands-free.

2. 🧰 Prerequisites

To use this template, you’ll need:

  • A self-hosted or cloud instance of n8n
  • A Surfe API Key
  • A Google Drive and Sheets account (with OAuth or service account)
  • A HubSpot account with access to create/update contacts (via OAuth or Private App Token)
  • The workflow JSON file (included with this tutorial)

3. 📌 Input File Format

To run the automation, you must upload a Google Spreadsheet to a specific folder in your Drive.

The spreadsheet must contain the following columns:

  • first name (required)
  • last name (required)
  • Either company name or company domain (at least one is required)
  • linkedin url (optional)

🛑 Important: Any row missing first name, last name, and both company name and company domain will be ignored automatically by the workflow.

Each row represents a person to enrich.
We recommend including the linkedin url if available, but it's not mandatory.

5. 🔄 How This N8N Workflow Works

  1. A new Google Sheet containing a linkedin_url column is added to a specific folder in Google Drive
  2. n8n detects the new file automatically via the Google Drive Trigger
  3. All rows are read and batched in groups of 500 to comply with Surfe’s API limits
  4. Each batch is sent to Surfe’s Bulk Enrichment API
  5. n8n polls Surfe until the enrichment job is complete
  6. It extracts the enriched contact data from Surfe’s response
  7. Only contacts with both email and phone number are kept
  8. These validated leads are pushed to HubSpot
  9. Finally, a Gmail notification is sent to confirm the job is complete

6. 🧩 Use Cases

  • Post-event contact enrichment – After a trade show, upload a list of LinkedIn profile URLs from badge scans or lead capture forms
  • Outbound LinkedIn campaign follow-ups – Gather LinkedIn URLs from manual outreach and enrich them into usable CRM leads
  • CRM data enhancement – Use LinkedIn URLs to fill in missing contact info for existing or imported contacts
  • List building from LinkedIn exports – Upload a list of LinkedIn profiles (e.g. from Sales Navigator) and turn them into fully enriched contacts in HubSpot

7. 🛠 Customization Ideas

  • 🔁 Add retry logic for failed Surfe enrichment jobs
  • 📤 Log enriched contacts into a Google Sheet or Airtable
  • 🔍 Add pre-check logic to avoid creating duplicates in HubSpot
  • 📊 Extend the flow to generate a basic summary report of enriched vs rejected contacts

8. ✅ Summary

This workflow turns a basic Google Sheet of LinkedIn URLs into fully enriched, CRM-ready contacts — automatically synced with HubSpot.

Just upload your file.

Let Surfe do the rest.
