How OpenAI API reaches your HighLevel account

MCP

HighLevel MCP. Connects straight to HighLevel's official MCP server with a Private Integration Token kept on your machine or server.

Set up OpenAI API with HighLevel in 3 steps

Get an OpenAI API key.
Add an mcp tool with HighLevel's URL and headers.
Run the request; the model discovers and calls HighLevel tools.

Python

import os
from openai import OpenAI
client = OpenAI()
resp = client.responses.create(
  model="gpt-5",  # use your current model
  input="List my 5 newest HighLevel contacts",
  tools=[{
    "type": "mcp",
    "server_label": "highlevel",
    "server_url": "https://services.leadconnectorhq.com/mcp/",
    "headers": {
      "Authorization": "Bearer " + os.environ["GHL_PIT"],
      "locationId": os.environ["GHL_LOCATION_ID"]
    }
  }]
)

Create the token in the sub-account under Settings → Private Integrations. Keep it in your environment, a secure prompt or the tool's credential store; never paste it into a shared file.
