Connect GoHighLevel to Everything. With N8N as the Engine.
GHL handles your CRM and communications. N8N handles the rest — AI processing, Slack alerts, contract automation, external databases, and any tool with an API. We build and deploy the integration layer between them.
How GHL and N8N Work Together
GHL is the event source and the CRM. N8N is the processor. They exchange data in real time via webhooks and API calls.
GHL fires a webhook on every trigger event
A lead fills in a form, a call is missed, a deal is moved to Won — GHL immediately sends a webhook containing the full contact record and event data to N8N's listener URL. This happens in real time, typically within 1–2 seconds of the event occurring.
N8N processes the data through your workflow logic
N8N receives the webhook, extracts the relevant fields, applies conditional logic (is this a hot lead? which industry? what pipeline stage?), calls external APIs or AI models if needed, and prepares the output for the next step.
N8N sends data to connected tools simultaneously
A Slack message to your team with full lead context. A row added to your Google Sheet pipeline report. A DocuSign envelope triggered for a new client. An AI-generated follow-up written by Claude. All happening in parallel, in seconds.
N8N writes the result back into GHL
The AI qualification score is written back to the contact's CRM field. The contact is tagged and moved to the correct pipeline stage. A GHL workflow is triggered based on the outcome. The CRM is always up to date without manual intervention.
Your automation data never touches a third-party server. Self-hosted N8N runs on a £10–20/month VPS — no per-task fees, full API access, and complete data sovereignty. Compared to Zapier at equivalent volume, this typically saves 70–85% in automation costs.
