Problem with Webhook and EvolutionAPI

n8n version: 1.91.3

  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
  • Operating system: Ubuntu 22.04

I have a development environment deployed with Dokploy on a VPS where I have several containers, including the n8n and EvolutionAPI containers.
I created a workflow with a simple Webhook node to test the integration with Evolution API, but the requests aren’t coming in.


I have tested the webhook by making this request with curl:

And the request is received

I created this simple server to listen for a webhook with Express and integrated it with the Evolution API. I exposed the URL to the internet using Ngrok. And it works.

Any suggestions or ideas on how to fix this? Thank you very much.
