Configure n8n webhooks with reverse proxy#

n8n creates the webhook URL by combining N8N_PROTOCOL, N8N_HOST and N8N_PORT. If n8n runs behind a reverse proxy, that won't work. That's because n8n runs internally on port 5678 but the reverse proxy exposes it to the web on port 443.

When running n8n behind a reverse proxy, it's important to do the following:

  • set the webhook URL manually with the WEBHOOK_URL environment variable so that n8n can display it in the editor UI and register the correct webhook URLs with external services.
  • Set the N8N_PROXY_HOPS environment variable to 1.
  • On the last proxy on the request path, set the following headers to pass on information about the initial request: 

1
2
export WEBHOOK_URL=https://n8n.example.com/
export N8N_PROXY_HOPS=1
Refer to Environment variables reference for more information on this variable.
