Whatsapp authentication accepted but trigger throws error

Questions

Hi, I am hosting n8n on a linux server running on docker. I tried to run the whatsapp trigger but it responds with an erroer (invalid parameter). the credentials are okay so I do not know what could go wrong with so few parameters to work on.

I noticed the webhook shown in the parameter configuration is
http://localhost:5678/webhook/f6fbcc89-2cdf-4c06-a3f6-dc30edada3d6

well it seems to me that can not work, can it? why does it show localhost and I am not able to change that? It should be reachable from outside …
thanks for any hints

  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hi @smartmart,

Welcome to the community :tada:

Have you configured your WEBHOOK_URL environment variable which is documented here?
