What you need
- The public URL of the n8n instance
- An n8n public API key
- An n8n plan that includes the public API
Create the n8n API key
- Sign in to n8n.
- Open Settings → n8n API.
- Choose Create an API key.
- Give it a clear label and expiration.
- If your n8n plan supports scoped API keys, choose the minimum scopes needed for the tools you intend to use.
- Copy the key. n8n shows it for you to store securely.
Connect the instance
- In ApexGenius, open Connections.
- Select n8n.
- Choose Connect n8n.
- Enter the instance URL, such as
https://your-workspace.app.n8n.cloud. - Paste the API key.
- Choose Connect. ApexGenius verifies the live instance before saving the connection.
- In your AI client, start with a safe read such as “List my n8n workflows.”
Review the available operations
When the n8n connection is active and healthy, its current 20 operations can appear in discovery. They cover workflow inspection, templates, generation, replacement, autofix, test runs, data tables, instance audit, and deletion. Your AI client still loads the same three public ApexGenius tools. Review the exact names and access types on the n8n connector page or in the MCP tool reference. The connected n8n account and ApexGenius authorization checks still determine what each operation can reach.Official n8n documentation
