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
- Create one Private Integration Token per sub-account, with only the scopes each integration needs.
- Connect agents through the HighLevel MCP server at services.leadconnectorhq.com/mcp/.
- Keep tokens in environment variables or secret stores, never in shared files.
