Transcribe & Summarize GoHighLevel Call Recordings with Whisper and GPT to CRM Notes

This n8n template automatically transcribes GoHighLevel (GHL) call recordings and creates an AI-generated summary that is added as a note directly to the related contact in your GHL CRM.

It’s designed for real estate investors, agencies, and sales teams that handle a large volume of client calls and want to keep detailed, searchable notes without spending hours on manual transcription.

Who’s it for

• Sales and acquisitions teams that want instant call notes in their CRM
• Real estate wholesalers or agencies using GoHighLevel for deal flow
• Support and QA teams that need summarized transcripts for review
• Any business owner who wants to automatically document client conversations

How it works

1. A HighLevel automation workflow triggers when a call is marked “Completed” and automatically sends a webhook to n8n.
2. The n8n workflow receives this webhook and waits briefly to ensure the call recording is ready.
3. It retrieves the conversation and message IDs from the webhook payload.
4. The call recording is fetched from GHL’s API.
5. An AI transcription node converts the audio to text.
6. A summarization node condenses the transcript into bullet points or a concise paragraph.
7. A Code node formats the AI output into proper JSON for GHL’s “Create Note” endpoint.
8. Finally, an HTTP Request node posts the summary to the contact’s record in GHL.

How to set up

1. Add your GoHighLevel OAuth credential and connect your agency account.
2. Add your AI credential (e.g., OpenAI, Anthropic, or Gemini).
3. Replace the sample webhook URL with your n8n endpoint.
4. Test with a recent call and confirm the summary appears in the contact timeline.

Requirements

• GoHighLevel account with API and OAuth access
• AI service for transcription and summarization (e.g., OpenAI Whisper + GPT)

Customizing this workflow

You can tailor this automation for your specific team or workflow:

• Add sentiment analysis or keyword extraction to the summary.
• Change the AI prompt to focus on “action items,” “objections,” or “next steps.”
• Send summaries to Slack, Notion, or Google Sheets for reporting.
• Trigger follow-up tasks automatically in your CRM based on keywords.

Good to know

• AI transcription and summarization costs vary by provider — check your LLM’s pricing.
• GoHighLevel’s recording availability may take up to 1 minute after the call ends; adjust the delay accordingly.
• For OAuth setup help, refer to GHL’s OAuth documentation.

Happy automating! ⚙️
