Vapi to GoHighLevel CRM Sync Call Summaries + Telegram

Automatically sync Vapi/Retell call summaries into GoHighLevel—then notify your team on Telegram

This n8n workflow listens for Vapi/Retell end-of-call webhooks, captures the caller details (including transcript + AI summary), updates/creates the contact in GoHighLevel, and sends a Telegram alert with the lead summary and recording link.

What this workflow does

• Receives webhook events via an n8n webhook endpoint and immediately acknowledges the payload.
• Filters for completed calls by checking for an end-of-call-report message type.
• Extracts call data from the webhook: caller phone number, transcript, AI-generated summary, recording URL, and structured lead details (name and intent).
• Syncs with GoHighLevel by phone number:
  • If no contact exists, it creates a new contact and tags it with ai-voice-lead and the detected intent.
  • If a contact exists, it appends an AI call summary and recording link as a note on the existing contact.
• Sends a Telegram notification containing the lead details, the AI summary, and the recording link.

Use cases

• Automatically capture every AI voice lead from Vapi or Retell and keep GoHighLevel contact notes up to date.
• Qualify and route inbound calls faster by tagging leads (via detected intent) as ai-voice-lead.
• Give your sales/ops team instant visibility using Telegram alerts with the summary + recording link.
