Connecting GoHighLevel to n8n via webhooks enables automation workflows that go far beyond GoHighLevel's native capabilities — enriching contacts with external data, triggering actions in third-party tools, and building multi-step processes that span multiple platforms. Here is how to set up the connection.
How the Integration Works
GoHighLevel can send data to n8n via webhooks — HTTP POST requests that fire when specific events occur in GoHighLevel (new contact created, form submitted, pipeline stage changed, etc.). n8n receives that webhook, processes the data, and can perform any number of actions: look up additional data from an API, write to a Google Sheet, send data to another platform, or trigger actions back in GoHighLevel via its API.
Step 1: Create a Webhook Node in n8n
In your n8n instance, create a new workflow. Add a Webhook node as the trigger. Set the HTTP method to POST. n8n generates a webhook URL — copy this URL. This is the endpoint GoHighLevel will send data to when events occur.
Step 2: Create a GoHighLevel Workflow That Fires the Webhook
In GoHighLevel, go to Automation > Workflows. Create a new workflow with your desired trigger (e.g., "Form Submitted" for a specific form). Add a "Webhook" action. Paste your n8n webhook URL. Configure the payload — select which contact data fields to send. Save and activate the workflow.
Step 3: Test the Connection
Submit a test form in GoHighLevel. In n8n, the Webhook node should show the received data in its output. Review the data structure — this is what your n8n workflow has to work with. Common fields included in a GoHighLevel webhook payload: contact ID, first name, last name, email, phone, form name, pipeline stage, tags, and any custom field values.
Step 4: Build Your n8n Processing Logic
With the webhook data received, add subsequent n8n nodes to process it. Common patterns: use the email or phone to look up the contact in Hunter.io for email verification, send the contact data to Apollo for enrichment, write a row to a Google Sheet for tracking, or call GoHighLevel's REST API to update the contact record with enriched data.
Step 5: Use GoHighLevel's API to Write Data Back
GoHighLevel has a REST API that n8n can call to update contacts, add tags, move pipeline stages, and trigger workflows. In n8n, use an HTTP Request node with GoHighLevel's API base URL (https://rest.gohighlevel.com/v1/) and your API key from GoHighLevel Settings > Integrations > API Key. This enables round-trip automation: GoHighLevel fires a webhook to n8n, n8n enriches the data externally, and n8n writes the enriched data back to the GoHighLevel contact record.
