AI Sales Call Summaries & HubSpot Follow-Ups with n8n

Turn every sales call into a HubSpot summary + follow-up—automatically

This n8n workflow captures a pasted call transcript from an n8n Form, matches the speaker to an existing HubSpot contact by email, then uses OpenAI to generate a structured 120–160 word call summary and a single actionable follow-up task—saving it back into HubSpot as a completed Call engagement and Task.

What this workflow does

• Ingests submissions: Receives a form submission with the contact’s email address and the call transcript text.
• Finds the right HubSpot contact: Searches HubSpot for the contact by email and retrieves key contact properties for context.
• Generates an AI sales call summary: Sends contact details + transcript to OpenAI to produce a structured JSON output containing a 120–160 word summary and one actionable follow-up task.
• Drafts and applies missing contact fields (optional): Uses the same OpenAI-guided flow to propose updates to missing HubSpot contact properties such as city, country/region, job title, and job function, then applies them to the contact.
• Logs the interaction in HubSpot: Records the generated summary as a completed Call engagement and associates it with the matched contact.
• Creates the follow-up task in HubSpot: Creates a HubSpot Task using the drafted task name and body, associated with the same contact.

Use cases

• Sales teams that paste call transcripts into an n8n Form and want HubSpot updated immediately.
• SaaS operators who need consistent follow-up documentation without manual note-taking.
• Automation engineers standardizing AI-driven HubSpot engagement logging for pipeline hygiene.
