n8n Public REST API

Use this skill when you need to drive n8n programmatically. It covers the same core actions you use in the UI: workflows, executions, tags, credentials, projects, and more.

Availability

• The public API is unavailable during the free trial.
• Upgrade your plan to enable API access.

Configuration

Recommended environment variables (or store in .n8n-api-config):

export N8N_API_BASE_URL="https://your-instance.app.n8n.cloud/api/v1"  # or http://localhost:5678/api/v1
export N8N_API_KEY="your-api-key-here"

Create the API key in: n8n Settings → n8n API → Create an API key.
