In your n8n instance:
- Log in as Admin or Owner.
- Select Settings > Usage and plan.
- Select Enter activation key.
- Paste in your license key.
- Select Activate.
Add a license key using an environment variables#
In your n8n configuration, set N8N_LICENSE_ACTIVATION_KEY to your license key. If the instance already has an activated license, this variable will have no effect.
Refer to Environment variables to learn more about configuring n8n.

n8n uses Cloudflare to host the license server. As the specific IP addresses can change, you need to allowlist the full range of Cloudflare IP addresses to ensure n8n can always reach the license server.
