What is the GoHighLevel API?

The GoHighLevel API is a secure gateway that lets you connect GHL with other tools and platforms.
Instead of using Zapier or manual exports, you can send and receive data directly using simple API requests.

Real-world use cases:

• Auto-sync leads from Facebook Ads into GHL with source tags
• Send Stripe invoices into GHL’s contact timeline
• Build reporting dashboards from CRM metrics
• Trigger AI summaries of incoming form data

Pro Tip: You don’t need to be a developer. With tools like Make.com or N8N, you can build API-powered automations visually.

How to Get Started with the GoHighLevel API

Step 1: Get your API key

• Go to Settings > Company > API Key
• Copy it and store it safely

Step 2: Test a basic call

• Use Postman or Make.com to test a GET /contacts call
• Confirm your headers and Location ID are set correctly

Step 3: Build something small

• Create a script or visual flow to log new contacts into Google Sheets or Airtable
