Evolution API Credentials Issue

I’m trying to send a WhatsApp message using the n8n-nodes-evolution-api community node. I’ve connected to a hosted Evolution API service (https://api.evoapicloud.com) and the credential test within n8n shows “Connection tested successfully” (as seen in the screenshot below).

However, when I try to execute the “Send Message” node, I receive the following error:

{
“code”: “ERR_INVALID_TOKEN”,
“message”: “Invalid api key”,
“variables”: {}
}

Here’s my setup and workflow:

n8n setup:

  • n8n version: 1.95.2 (Self Hosted)
  • Database: SQLite (default)
  • EXECUTIONS_PROCESS: own
  • Running n8n via: Docker
  • Operating system: Linux (based on the path in the error details)

Workflow:

Any ideas? I’m happy to explain/share anything else if needed.
Thanks

Hey, for full community node support, you’ll need to ask the creator. As an alternative, you could try following the API Evolution documentation and integrating it with an HTTP Request node in N8N.

Here’s an example, as I happen to use the Evolution API myself."
