You need to add your enterprise license key to enable enterprise features. You can do this through the UI, or using environment variables.

Add an enterprise license key in the UI

In your n8n instance:

1. Select Settings > Usage and plan.
2. Select Enter activation key.
3. Paste in your license key.
4. Select Activate.

Add an enterprise license key using environment variables

In your n8n configuration, set N8N_LICENSE_ACTIVATION_KEY to your license key.

Refer to Environment variables to learn more about configuring n8n.

Allowlist the license server IP addresses

n8n uses Cloudflare to host the license server. As the specific IP addresses can change, you need to allowlist the full range of Cloudflare IPs{:target=_blank .external-link} to ensure n8n can always reach the license server.
