What Is the GoHighLevel API?
The GoHighLevel API is a REST-based developer interface that gives you access to nearly every object in the platform:
- Contacts
- Opportunities
- Workflows
- Campaigns
- Appointments
- Custom Fields
- Conversations
You can create, update, delete, and fetch data. It’s the backend power tool behind most white-label SaaS automations.
Who Should Use the API?
- SaaS builders wanting to connect GoHighLevel with custom tools
- Developers building middleware or integrations
- Agencies adding advanced client features
- CRM Migrators syncing data between platforms
If you’ve hit the limits of Zapier or Make, the API gives you full control.
Use Case: Custom Lead Scoring System
Problem: A B2B sales agency needed more advanced scoring than GHL provided.
Solution:
- API checks contact history daily
- Applies weighted scores based on email opens, form fills, and replies
- Updates a custom field in GHL
- Triggers automation if score crosses a threshold
This setup gave the client actionable insights without logging in.
