How can I configure WEBHOOK_URL in n8n without affecting the password reset URL?

You’ll need to decouple the custom prefix for the webhook endpoints from the base URL used in communications like password reset emails. In your case, the WEBHOOK_URL environment variable is applied globally, which is why the custom prefix appears in the password reset URL.

To fix this:

1. Set WEBHOOK_URL Without the Custom Prefix
   Configure WEBHOOK_URL to point to your base domain without the extra prefix. For example:

   BASHCopied
   export WEBHOOK_URL=https://${SUBDOMAIN}.${DOMAIN_NAME}/

2. Customize Webhook Endpoints Separately
   Use the dedicated environment variables to adjust the webhook endpoint paths. From the endpoints documentation you can define:

   BASHCopied
   export N8N_ENDPOINT_WEBHOOK=randomstring/webhook
   export N8N_ENDPOINT_WEBHOOK_TEST=randomstring/webhook-test

This way, the base WEBHOOK_URL (which is used for things like password reset emails) remains unchanged, while your webhook endpoints include the custom prefix as desired.

With these changes, your webhook calls will target URLs like:

https://app.mydomain.com/randomstring/webhook
https://app.mydomain.com/randomstring/webhook-test

and your password reset URL will correctly appear as:

https://app.mydomain.com/change-password?token=randomtokenstring&mfaEnabled=true

This configuration works with n8n version 1.80.3 running in Docker, and it leverages the built-in environment variables designed to customize endpoint paths without affecting other system URLs.
