Hey folks 
I’ve been trying to test Telegram, WhatsApp, and Discord integrations on an n8n workflow hosted locally on my Mac (via Docker), and I keep running into a wall with the webhook URLs.
I know I’m supposed to use something like ngrok to expose my local server. I did that, and I can get a public URL just fine. But here’s the problem: I can’t figure out how to edit the webhook URLs in the various triggers inside n8n. They still point to localhost, and the external services obviously can’t reach that.
Is there a proper way to configure n8n so that it uses my ngrok URL instead of localhost when setting up the webhook triggers? Or is there a workaround I’m missing?
Would love to hear how others have tackled this!
