Typeform to HubSpot Upsert with Slack Alerts (n8n Workflow)

Automatically push Typeform leads into HubSpot—and get Slack alerts when it succeeds or fails

This n8n workflow connects Typeform submissions to HubSpot contacts (create or update), while posting a Slack notification so your team knows exactly when a lead has been upserted—or when something goes wrong.

What this workflow does

• Triggers on new Typeform responses from a specified form.
• Extracts and cleans lead data from the Typeform payload, including:
  • Splitting the lead’s name into parts
  • Lowercasing the email
  • Normalizing the phone number
  • Capturing the website URL
• Upserts a HubSpot contact using the submitter’s email, mapping collected fields to HubSpot contact properties.
• Posts a Slack alert:
  • Success alert including the HubSpot contact ID
  • Error alert with an error message and relevant payload for debugging
• Includes routing logic using if to handle success vs. failure outcomes.

Use cases

• Lead capture for SaaS: keep HubSpot contacts current with every new Typeform submission.
• Sales & marketing ops: receive immediate Slack notifications when a contact is upserted.
• Operations debugging: get error details in Slack to quickly identify data issues or HubSpot problems.
• Data quality enhancements: customize for deduplication, email verification, and other checks.

Technical details

• Typeform Trigger for new response events
• Code node for field extraction/normalization
