Slack Node Issue: How to Force HTTPS for Webhook and Trigger URLs in n8n?

[Daniel5]

I’m having issues with the Slack node, where I need the Slack Trigger and Webhook links to be in https://, but my n8n only generates links with http. How can I change this?

Not on the localhost, but you need to register one domain address to upload Webhook_url. Configure webhook URLs with reverse proxy | n8n Docs

I hope this question from before will help.

How to change localhost:5678 from webhook url?

Can you please let us know which command you ran? Also when you say “Inside” container. thought you are using docker, and you run the command by passing environment variable in -e WEBHOOK_URL format to it? So much better if you can share your entire command you ran

I need help doing this, I just dont understand how to enable 443. Im using docker and n8n

There are two semi simple options to achieve this:

1. Get a domain

2. Setup a reverse proxy with docker that handles https and certificates (let’s encrypt with acme). Something like caddy, nginx, treafik, etc.
   OR
   Use cloudflare tunnels and setup a cloudflared account. Cloudflare is effectively a reverse proxy that also handles https and certificates but free in the cloud.

If this is all to complex, think about getting the n8n cloud subscription where https is built in.
