Webhook Validation on Whatsapp API - Through Railway

Describe the issue/error/question

I’m not able to validate my webhook through whatsapp API on Railway. Since I already achieved this in the desktop version of n8n.

What is the error message?

Please share the workflow

Information on your n8n setup

  • n8n version: 0.211.1
  • Database you’re using: Postgres
  • Running n8n via: Railway

If this is already working for you outside of Railway, it seems like the webhook isn’t reaching your n8n instance. I am a Railway user, so you might need to check directly with them. In general, you want to make sure their reverse proxy server passes on all relevant requests to your n8n instance.
