Summarize Sales Calls in HubSpot with GPT-4.1 (n8n)

Turn HubSpot sales call transcripts into summaries, follow-up tasks, and CRM updates—automatically

This n8n workflow takes a pasted sales call transcript from an n8n form, finds the matching HubSpot contact by email, uses GPT-4.1 to generate a concise call summary and an actionable follow-up task, and then logs everything back into HubSpot.

What this workflow does

• Receives input: Accepts a form submission containing a contact’s email address and the call transcript.
• Finds the contact in HubSpot: Searches HubSpot for the contact by email and retrieves key contact properties.
• Generates AI outputs with OpenAI (GPT-4.1): Sends the contact details and transcript to OpenAI to produce:
  • a 120–160 word call summary
  • one actionable follow-up task (task name + task body)
  • suggested updates for missing HubSpot contact fields
• Optionally updates contact fields: Updates HubSpot contact properties such as city, country/region, job title, and job function when details are present in the transcript.
• Creates CRM records:
  • Creates a completed Call engagement in HubSpot with the AI-generated summary and associates it with the contact.
  • Creates a HubSpot Task engagement using the AI-generated task name and task body and associates it with the same contact.

Use cases

• After a sales call, automatically document the conversation and create next steps in HubSpot.
• Reduce manual CRM admin by updating missing contact details directly from transcript content.
• Keep call history consistent by logging summaries and tasks without switching tools.
