  • Copy your API key.

Pro  Tips

Keep your API key secure. Never share it publicly.

Understand the API Request Format

GoHighLevel’s API works using JSON data. When you send a request, you must include headers and a body (your data).

Key API Components:

  • Endpoint (URL): The link to which you send the request.
  • Headers: Tells the system how to process the request.
  • Body: The data you want to send (e.g., contact details).

 Tip: Use API documentation for reference. GHL updates endpoints occasionally.

Choose Your API Request Method

To send data, use the POST method. This differs from GET (which retrieves data) and PUT (which updates existing data).

Example: Adding a Contact

  • To add a new contact in GHL, send a POST request to:

Pro Tips

Always include “Authorization” in the headers to authenticate the request.

Send the API Request Using a Tool

You can send the request using different methods:

Using Postman (Easiest Way)

  • Open Postman.
  • Select POST as the method.
  • Paste the API endpoint.
  • Add headers (Authorization & Content-Type).
  • Paste the body in JSON format.
  • Click Send and check the response.

Double-check your API key and JSON formatting if you get an error.

Automate With No-Code Tools

If you’re not a developer, you can still use Zapier or Make (Integromat) API requests.

  • Create a new Zap.
  • Choose Webhook by Zapier as the trigger.
  • Select POST Request.
  • Enter the API URL and data.
  • Test and activate your Zap.

This method is excellent for automating lead entries from other apps into GoHighLevel.

Troubleshooting Common Issues

  • If you run into errors, check these common problems:
  • Wrong or missing API key. 
  • Incorrect JSON formatting. 
  • The GHL system might be down—try again later. 
  •  GHL may block excessive requests—space them out.

Always check GoHighLevel’s API status page for updates.
