HighLevel's description: "Connect your CRM to any tool you use with full API access."

## Why it matters
Every serious agent or integration needs reliable API access. It's what lets Claude, ChatGPT, n8n and your own tools read and act on CRM data.

## How to take advantage of Advanced API Access
1. Create one Private Integration Token per sub-account, with only the scopes each integration needs.
2. Connect agents through the HighLevel MCP server at services.leadconnectorhq.com/mcp/.
3. Keep tokens in environment variables or secret stores, never in shared files.
